一个网页打印机可以配置为支持任何数量的笔,并且一个笔可以用于任何数量的网页打印机。 A netpage printer can be configured to support any number of pens, and a pen can be used for any number of netpage printer. 在优选实施例中,每个网页笔有一个唯一的标识符。 In a preferred embodiment, each page pen has a unique identifier. 一个家庭可以有一组有颜色的网页笔,每一个笔分配给家庭的一个成员。 A family can have a set of color pages pen, each pen is assigned to a member of the family. 这使得每个用户相对网页出版物服务器或应用服务器有一个不同的特征数据。 This allows each user relative web publication server or application server has a different characteristic data.

一个网页笔还能够在网页注册服务器11上注册并且连结于一个或多个支付卡帐户。 A page pen can also be registered on the website registration server 11 and linked to one or more payment card accounts. 这使得利用网页笔安全地授权电子商务支付。 This makes the pen safely use web e-commerce payment authorization. 网页注册服务器将由网页笔捕捉的签名和已经注册的签名做比较,以允许将用户的身份授权给电子商务服务器。 Registration server by web pages pen signature capture and registered signature comparison, to allow authorized user's identity to the e-commerce servers. 其他的生物特征也可以用于核实身份。 Other biometrics can also be used to verify identity. 网页笔的一种形式包括指纹扫描,以类似的方式由网页注册服务器核实。 A form of pen includes fingerprint scanning the page, in a similar way to verify the registration by the web server.

尽管网页打印机可以发送诸如晨报的期刊而不需用户介入,但它可以配置为从不接收未经请求的垃圾邮件。 Although the page printer can send periodicals such as morning without user intervention, but it can be configured to never receive unsolicited spam. 在其优选实施例中,它只发送来自预订的或授权的来源的期刊。 In its preferred embodiment, it only sends periodical sources from the reservation or authorized. 在此方面,网页打印机不同于传真机或e-mail帐户,其中后者对于知道电话号码或者e-mail地址的任何垃圾邮件发送者来说是可见的。 In this regard, the page printer is different from the fax machine or e-mail account, the latter for any spammers know the phone number or e-mail address is visible.

系统中的每个对象模型利用标准建模语言(UML)分类表描述。 Each object in the model system using standard modeling language (UML) classification description. 一个分类表包括通过各种关系结合的一组对象类,并且这里只关心两种关系:关联和类化。 A catalog includes a set of object classes joined by a variety of relationships, and the only concern here two relationships: associations and class-oriented. 关联表示对象之间,即类的个例之间的某些关系。 Association represents some kind of relationship between a case that is between objects. 类化描述实际类,可以理解为:如果把一类认为是该类的所有对象的集合,并且类A是类B的类化,则B只是A的一个子集。 Class of describing the actual class, can be understood as follows: If a category considered to be a collection of all objects of the class, and the class A class B class of, then B is just a subset of the A's. 每个类表示成贴有该类名称的标签的矩形框。 Each class represents a rectangular box labeled with the class name of the label. 它包含一栏类的属性,由一条水平线将其和名称分开;以及一栏类的运算指令,由一条水平线将其和属性栏分开。 It includes a bar the property by a horizontal line to separate and name; and a bar the operation instructions, and consists of a horizontal line to separate the property bar. 关联表示成连结两类的一条线,可选地在任一端标有关联的重数。 Represented as a line connecting related categories, optionally labeled at either end associated multiplicity. 缺省重数是一。 The default multiplicity is one. 星号(*)表示"许多"重数,即零或多个。 An asterisk (*) indicates "many" multiplicity, that is, zero or more. 每个关联可选地标有其名称,并且还可选地在任一端标有对应的类的作用。 Each association is optionally labeled with its name, and optionally also end labeled for the role of class in the office. 空菱形块表示聚集关联("是一部分"),并且画在关联线的聚集端。 Empty diamond blocks represent aggregation association ("is part of"), and draw the line at the end of the association gathered. 类化关系("是一个")表示成连结两类的实线, 在类化端有一个箭头(空三角形形式)。 Type of relationship ("a") is expressed as a solid line connecting two, in the class of the end with an arrow (empty triangle form). 当一个分类表分解成多个图表时,任何完全相同的类除了确定该类的主图表以外全部由虚线轮廓线表示。 When a classification into multiple diagrams, any class in addition to determine the exact same class all the main chart is represented by a dotted outline. 只在确定类的地方表示有属性。 Only in determining the kind of place expressed attribute. 网页是建造网页网络的基础。 Is the basis for the construction of web pages of the network. 它们提供了一个公布信息和交互服务的基于纸的用户接口。 They offer a release of information and interactive services paper-based user interface. 一个网页包括一个打印页面(或者其他表面区域),不可见地标记有该页面的联机说明的坐标。 A web page includes a printed page (or other surface region) invisibly marked with the coordinates of the online description of the page. 联机页面说明由网页页面服务器持续保持。 Online page illustrated by the web page server continued to maintain. 网页说明描述了页面的可见的版面和内容,包括文本、图片和图象。 Web page description describes the visible layout and content, including text, pictures, and images. 它还描述了页面上的输入元件,包括按钮、超级链接和输入区。 It also describes the input elements on the page, including buttons, hyperlinks, and input fields. 网页允许网页系统同时捕捉和处理由网页笔在网页表面上所做的标记。 Web pages system allows simultaneous capture and processing marking pen on the page by the web surface made. 多个网页可以共享同一个页面说明。 Multiple pages can share the same page description. 但是,为了能够分别通过各个相同的页面的输入,每个网页赋有一个唯一的标识符。 However, in order to be able to separately input the same through each page, each page has a unique identifier assigned. 这个页面ID 具有足够的精确度以分别大量的网页。 This page ID has sufficient precision to a large number of pages, respectively. 页面说明的每个坐标用打印的标识符编码。 Page description of each coordinate with the identifier encoded print. 标识符确定了其上有标识符的唯一页面,并且从而直接确定了页面说明。 A unique identifier to determine on which page identifier, and thereby directly determines the page description. 标识符还确定了它在页面上的位置。 Identifiers also determine its position on the page. 以下详细说明标识符的性质。 The following detailed description of the nature of the identifier. 标识符用红外吸收墨水打印在任何反射红外线的基层上,例如普通纸。 Identifier infrared absorption ink printed on any infrared-reflecting grass-roots, such as plain paper. 近红外线波长肉眼不可见,但可以容易地由具有适当过滤器的固态映象传感器检测到。 Near-infrared wavelengths invisible to the naked eye, but can be readily prepared from the solid-state image sensor with an appropriate filter is detected. 标识符由网页笔上的一个区域映象传感器检测到,并且标识符数据通过最近的网页打印机被传送到网页系统。 Identifier image sensor by a regional web page on the pen is detected, and the identifier data recently transferred to the web page printer system. 笔是无线的并且通过近程无线电线路和网页打印机通信。 The pen is wireless and the printer communicate through short-range radio link to this page. 标识符足够小并且稠密布置,从而即使单击页面笔也能够可靠地映象至少一个标识符。 Identifier sufficiently small and densely arranged that even if you click page pen can reliably image at least one identifier. 在每次和页面交互时笔识别页面ID和位置很重要,因为该交互是无形的。 When each interaction with pen and page recognition page ID and location is important because the interaction is invisible. 标识符可纠错地编码以便使它们部分地容忍表面破损。 Error correction coding identifier may be tolerated so that they partially damaged surface.

网页页面服务器为每个打印网页维持一个唯一的页面个例,允许它为每个打印网页的页面说明上的输入区保持一个独有的用户提供值 Web page server maintains a unique example of a page for each print page, to allow it to enter the area of each printed page of the instructions on the page to keep users a unique value

集合. Collection.

网页说明、网页个例、以及打印网页之间的关系表示在图3中。 Imprint, Relations page of a case, and print pages between the representation in Figure 3. 打印网页可以是打印网页文件45的一部分。 Print a Web page can be part of the print page document 45. 网页个例关联于打印它的网页打印机以及,如果已知,请求该网页个例的网页用户。 Cases associated with a web page to the printer to print it and, if known, the page the user requested a case of the page.

在一个优选形式中,每个标识符确定它所在的区域,以及它在该区域内的位置。 In one preferred form, each identifier to determine it in the region, as well as its position in the region. 一个标识符还包含相关于整个区域或该标识符的特征位。 Also includes an identifier associated with the identifier of the entire area or flag. 一个或多个特征位,例如,可以向标识符检测装置发送信号以提供代表关于标识符当前区域的一个函数的反馈,而不必需要检测装置指向区域的说明。 One or more flag, for example, can send a signal to the identifier detection means representing a function to provide feedback on the identifier of the current region, without necessarily requiring the detection means to the zone described. 一个网页笔,例如,可以当处于超级链接区时使一个"激活区"LED发亮。 Pen a page, for example, can make a "active region" LED lights up when in hyperlink area.

在一个优选实施例中,每个标识符包含一个易于识别的常量数据结构,它有助于初始检测,并且它有助于减小由表面或者检测过程引起的任何偏差作用。 In a preferred embodiment, each identifier comprising an easily recognizable constant data structure, which helps the initial detection, and it helps to reduce the effect of any variation or the detection process by the surface caused. 标识符优选地平铺显示在整个网页上,并且足够小且稠密布置,从而即使单击页面笔也能够可靠地映象至少一个标识符。 Identifier preferably tile the entire page, and is sufficiently small and densely arranged that even if you click page pen can reliably image at least one identifier. 在每次和页面交互时笔识别页面ID和位置很重要,因为该交互是无形的。 When each interaction with pen and page recognition page ID and location is important because the interaction is invisible. 在一个优选实施例中,和一个标识符相关的区域与整个页面相符,并且因此以该标识符编码的区域ID和该标识符所在页面的页面ID 一致。 In one preferred embodiment, and an area identifier matches the entire page, and thus to the region encoding the identifier and the identifier ID of the page where the page ID is consistent. 在其他实施例中,和一个标识符相关的区域可以是一个页面或其他表面的一个任意子区域。 In other embodiments, and an identifier associated with a region may be a page or any other surface of the sub-area. 例如,它可以和一个交互元素的区域相符,在该例中,区域ID可以直接确定交互元素。 For example, it can be an area of interactive elements correspond, in this example, the region ID can directly determine the interactive elements.

每个标识符典型地包含16位标识符ID,至少90立区域ID,以及许多特征位。 Each identifier typically contains 16 identifier ID, at least 90 stand area ID, and many features bits. 假定最大的标识符密度是每平方英寸64个,则16位标识符ID支持的区域尺寸可达1024平方英寸。 The maximum density is assumed identifier 64 per square inch, the 16-bit identifier ID support area sizes up to 1024 square inches. 仅通过利用相邻的区域和映象而不需增大精确度就可以连续映象较大的区域。 Only through the use of the adjacent area and the image without the need to increase the accuracy of continuous image can be larger area. 区域ID和标识符ID的区别在于方便性。 Distinguished area ID and the identifier ID is convenience. 对于绝大多数目的来说,二者的结合可以认为是全局唯一的标识符ID。 For most purposes, the combination of the two can be considered as a globally unique identifier ID. 相反地,还很方便将数据结构导入标识符ID,例如以便确定标识符的x和y坐标。 In contrast, very easy to import the data structure identifier ID, for example in order to determine the x and y coordinates identifiers. 一个卯位的区域ID 允许唯一地确定29()(约1027或一千万亿万亿)个不同的区域。 A d-bit region ID allows to uniquely identify 29 () (approximately 1027 or 1000000000000000 trillion) different regions. 标识符还可以包含类型信息,并且一个区域可以由多种标识符类型标识。 Identifier may include the type of information, and a region identifier type can be identified by a variety. 例如, 一个区域可以由编码x坐标的一组标识符和与第一组交织的编码y坐标的另一组标识符来标识。 For example, one region may identifier encoding x coordinates of a set of identifiers and another group with the first group of interleaved coded y coordinates to identify.

在一个实施例中,120位标识符数据利用(15, 5)里德-所罗门(Reed-Solomon)代码冗余编码。 In one embodiment, data utilization identifier 120 (15, 5) Reed - Solomon (Reed-Solomon) code redundancy coding. 这产生出含有6个代码字,每个代码字有15个4位码元的360个编码位。 This produces a code word containing 6, each code word 15 4-bit symbols 360 coded bits. 该(15, 5)代码使得每个代码字达到5个可纠错的码元,S卩,它可以允许每个代码字的码元错误比例达到33%。 The (15, 5) code to make each code word reached five correctable symbols, S Jie, it allows symbols of each code word error ratio reached 33%. 每个4位码元以空间相干的方式表示在标识符中,并且该六个代码字的码元在标识符中空间交织。 Each 4 yards yuan to spatially coherent representation of the identifier, and the six code word symbols in identifiers space intertwined. 这保证区间误差(一种影响多个空间相邻的位元的误差)总体上破坏很小数量的码元以及任何一个代码字中的很小数量的码元,这样增加了完全纠正区间误差的可能性。 This ensures that the interval error (an affecting multiple spatially adjacent bits of error) destruction of a small number of symbols, and any one code word of the small number of symbols on the whole, thus increasing the range of fully corrected errors possibility.

可以使用任何合适的纠错代码以代替(15, 5)里德-所罗门代码, 例如,具有或多或少冗余度的里德-所罗门代码,具有相同或不同码元和代码字数量的里德-所罗门代码;另一种分组代码;或者一种不同类型的代码,比如巻积代码(例如,参见Stephen B, Wicker所著的"数字通信和存储的误差控制系统"(Error Control System for Digital Communication and Storage), Prentice-Hall出版公司1995年出版,其内容包含于本文作为参考)。 You can use any suitable error correction codes in place (15, 5) Reed - Solomon code, for example, has more or less redundancy Reed - Solomon code, having the same or different symbols and code words in numbers Germany - Solomon codes; another grouping of code; a code or a different type, such as Volume product code (for example, see Stephen B, Wicker book "digital communication and storage of error control system" (Error Control System for Digital Communication and Storage), Prentice-Hall Publishing Company published in 1995, the contents included herein by reference).

表示在图4a中并在我们较早的申请PCT/AU00/00569中说明的标识符物理表示的一个实施例,包括固定目标结构15、 16、 17以及可变数据区18。 Shows an embodiment in FIG. 4a identifiers physical and our earlier application PCT / AU00 / 00569 described representation, including the fixed target structures 15, 16, 17 and the variable data region 18. 固定目标结构允许诸如网页笔的检测元件检测标识符并推测其相对于传感器的三维方位。 Fixed targets such as web pages pen structure allows detection elements identifiers and speculated with respect to three-dimensional position sensor. 数据区包括编码标识符数据的各 The data area including the encoded data identifier

个位元的表示。 A bit of representation. 为了减小尺寸,每个数据位元由径向楔形体表示,该径向楔形体的形式是一个由两条径向线和两条同心圆弧界定的区域。 To reduce the size of each data bit is represented by a radial wedge, form the radial wedge is a region made up of two radial lines and two concentric arcs defined.

每个楔形体有一个在1600dpi下8象素的最小尺寸,并且设计为使得 Each wedge has a minimum size at 1600dpi 8-pixel, and is designed to make

其基部(内弧)至少等于这一最小尺寸。 Its base (inner arc) at least equal to the minimum size. 楔形体的径向高度总是等于最小尺寸。 Radial height of the wedge is always equal to the minimum size. 每个4位数据码元由2x2的楔形体阵列表示。 Each of the four data symbol is represented by an array of 2x2 of the wedge. 六个代码字中的每一个的十五个4位数据码元以交织的方式分配给四个同心的码元环18a到18d。 Six codewords fifteen four data symbols of each of the elements to be allocated to the four interleaved concentric ring symbol 18a to 18d. 码元沿围绕标识符的圆环形连续系列交替分配。 Symbol identifier along around a circular continuous series of alternating distribution. 交织设计为使得同一个代码字的任何两个码元之间的平均空间距离最大。 Interleaving is designed so that the average space between any two symbols of a code word from the same maximum.

为了支持通过检测元件与被标记区域"单击"交互作用,不论检测元件位于区域的任何地方或任何方向,检测元件都必须能够在其视场内看到至少一个完整的标识符。 In order to support the element by detecting the labeled region "click" interaction, regardless of the detection element located anywhere in the area or in any direction, the detection device must be able to see at least one complete identifier in its field of view. 因此检测元件的视场的必要的直径是标识符尺寸和间距的一个函数,假定是圆环形的标识符形状,则当标识符平铺显示在一个等边三角形网格上时可得到传感器视场193的最小直径,如图4b所示。 Therefore, the diameter of the field of view necessary detection element is a function of the size and spacing of identifiers, assuming the shape of a circular ring is the identifier is obtained when the sensor depends on an equilateral triangle mesh when the identifier Tile The minimum diameter of the field 193, shown in Figure 4b.

图6示出由诸如网页笔的检测元件进行的标识符处理和解码。 Figure 6 shows the detection and decoding processing by the identifier element such as a pen on the page carried out. 当从映象传感器得到所捕捉映象时,确定映象的动态范围(20)。 When the captured image obtained from the image sensor to determine the dynamic range of the image (20). 该范围的中心值随后选择为映象的二元阈值(21)。 The center of the range and then select the image binary threshold (21). 随后该映象被阈化并分割成相连结的象素区(即形状23) (22)。 The image is then divided into phases and the threshold of the pixel connected regions (i.e. shapes 23) (22). 那些小的不能表示标识 Those little identity can not be represented

符结构的形状被舍弃掉。 Shape descriptor structure is discard. 还要计算每个形状的大小和质心。 Also calculated for each centroid size and shape.

然后计算每个形状的二元形状静矩25 (24),这些提供了顺序定位目标结构的基础。 Is then calculated for each static Binary shape moments 25 shape (24), which provides the basis for the sequence of the target structure. 中心形状静矩位置必然不变,并且很容易地使比例、长宽比和旋度不变。 Static Moment center position necessarily the same shape, and easily make the ratio, aspect ratio and rotation invariant.

首先定位环形目标结构15 (26)。 First positioning ring target structure 15 (26). 环形具有当观察失真时运转良好的优点。 Ring distortion when viewed with a good run advantage. 通过将每个形状的静矩方位规格化和旋度规格化进行匹配。 The quiet moments normalized by the orientation and rotation of each shape normalized match. 当其二级静矩被规格化后环形易于被识别,即使观察失真相当严重。 When the secondary static moments are normalized the ring is easy to be recognized, even if the observed distortion is very serious. 环形的原始方位和旋度27 —起提供了观察变换的有用的近似值。 Annular position and rotation of the original 27 - from observation provides a useful approximation conversion.

随后定位轴向目标结构16 (28)。 Structure 16 is then positioned axially target (28). 通过将环形的规格施加于每个形状的静矩,并且将所得到的静矩旋度规格化进行匹配。 By annular specifications applied to the static moments of each shape, and the static moments of the resulting normalized rotation to match. 当其二级静矩被规格化后轴向目标易于被识别。 When the secondary axial static moments are normalized target is easily identified. 注意要求三级静矩以明确轴线的两种可能方位。 Note requires three quiet moment to clarify the axis of the two possible orientations. 形状有意斜向于一侧以便使其成为可能。 Shape in a side oblique intends to make it possible. 还要注意当轴向目标被施加环形的规格后只是有可能将轴向目标旋度规格化, 因为观察失真可以隐藏轴向目标的轴线。 Also note that when the target is likely to be applied after the axial annular target specification axial rotation normalized, because observation of distortion can hide the axis of the axial goals. 轴向目标的原始旋度由于笔侧偏29而提供了标识符旋度的一个有用的近似值。 Original target due to the axial rotation of the pen cornering 29 and provides a useful approximation identifier curl.

最后定位四个观察目标结构17 (30)。 Last positioning four observation target structure 17 (30). 根据它们相对于环形和轴向目标、环形的方位和旋度、以及轴线的旋度的已知的空间关系计算正确的位置估算值。 Based on their objectives with respect to the ring and axial, orientation and rotation of the ring, and the axis of rotation of the known spatial relationship to calculate the correct position estimate. 通过将环形的规格施加于每个形状的静矩进行匹配。 By specification applied to each annular shape to match the static moments. 当其二级静矩被规格化后圆环形观察目标易于被识别,并且最接近每个估算的位置的目标认为是匹配。 When the secondary static moments are normalized circular observation target easily identified and closest to the target location of each estimate considered a match. 该四个观察目标的原始质心随后成为标识符空间内的已知尺寸的观察失真的角31,并且根据求解关于四个标识符空间和映象空间的点偶的广为人知的方程(参见Heckbert, P.的"结构映象和图象变形的基本原理"(Fundamentals of Texture Mapping and Image Warping),伯克利加州大学EECS系硕士论文,技术报告号UCB/CSD 89/516, 1989年6月,其内容包含于本文以做参考)推出八自由度观察变换33 (32)。 The four observation target centroid of the original observation subsequently became known dimensions identifier space distortion angle 31, and according to the well-known equation solving even on point four identifier space and image space (see Heckbert, P . "basic principles of texture mapping and image deformation" (Fundamentals of Texture Mapping and Image Warping), EECS, University of California, Berkeley Master's thesis, technical report No. UCB / CSD 89/516, 1989 In June 2009, the contents of which contain in this paper for reference) introduced eight degrees of freedom transform 33 observed (32).

所推出的标识符空间向映象空间的观察变换用于将标识符空间中的每个己知的数据位元位置投射到映象空间中,在该映象空间内,实值的位置用于将四个相应毗邻的相素双线形地插入到输入映象中 The launch of the identifier space transformation identifier space for each known data bit position is projected onto the image space to observe the image of the space within the image space, the location of real value for The four corresponding adjacent Pixel bilinear inserted into the input image

(36)。 (36). 前面计算的映象阈值21用于限定结果以生成最终的位元值37。 Mapping the previously calculated threshold for defining results 21 to generate the final 37 bit value.

当以此方式得到所有360个数据位元37,六个60位里德-所罗门代码字中的每一个被解码(38)以产生20个解码的位元39,或者总共120个解码的位元。 When in this way to get all 360 data bits 37, six 60 Reed - Solomon code word each is decoded (38) to produce 20 decoded bits 39, or a total of 120 decoded bits . 注意代码字码元以代码字的顺序表示,从而代码字在表示过程中被隐含地解交织。 Note that the code word symbols in the code word sequence of said code word in order to express the process of being implicitly deinterleaving.

仅在映象的子区内可以寻找环形目标15,如果可以看到环形, 该子区相对于环形的关系是它是一个完整标识符的一部分。 Only the sub-region in the image of the target 15 can look for the ring, if you can see the ring, with respect to the relationship between the sub-region is part of the ring it is a complete identifier. 如果完整的标识符不可看到,并且成功解码,则当前桢没有记录笔的位置。 If you can not see the complete identifier, and successfully decoded, the current frame is not recorded position of the pen. 如果有足够的处理能量和理想的非最小的视场193,另一种策略是在当前映象中寻找另一个标识符。 If there is sufficient field of view of non-minimal processing power and an ideal 193, another strategy is to look for another identifier in the current image.

所得到的标识符数据表示了区域的身份,包括标识符以及标识符在区域内的位置。 Identifier data obtained indicates the identity of the region, including an identifier and an identifier of the location in the region. 笔尖在区域内的精确位置35,以及笔的总体方位35, 则由在标识符上发现的观察变换33和已知的笔的物理轴线和笔的光学轴线之间的关系可以推知。 Observe the precise location of the tip in the region of 35, and the overall orientation of the pen 35, the identifier is found by converting pen 33 and known relationship between the optical axis physical axis and the pen can be inferred.

上述标识符结构设计为允许平表面的规则平铺和非平表面的不规则平铺。 The identifier structure is designed to allow an irregular flat surface tile tiled rules and non-flat surfaces. 一般来说,在非平表面上不可能规则平铺。 In general, the rules on non-flat surfaces can not be tiled. 在平表面的可以规则平铺标识符的更为有用的例子中,即诸如纸张等的表面,可以使用更多的有效标识符结构,其中有效标识符结构利用了平铺的规则特性。 More useful example of the flat surface can be tiled rule identifiers, that such surface of the paper or the like, can be used more effectively identifier structure in which the effective use of the rule identifier structure characteristic tiled.

图5a表示了另一种更适合于规则平铺的标识符结构。 Figure 5a shows a more suitable alternative rule identifier tile structure. 标识符4是正方形的并且有四个观察目标17。 Identifier 4 is square and has four observation target 17. 该结构类似于Bennett等人的美国专利5,051,746中所述的标识符。 The structure is similar to Bennett et al., U.S. Patent No. 5,051,746 in the identifier. 标识符有六十个4位里德-所罗门码元47,总数是240个位元。 There are sixty four identifiers Reed - Solomon symbols 47, the total number is 240 bits. 标识符将每一个位元表示为一个点,将每个零位元表示为没有相应的点。 Each bit identifier is represented as a point, each zero bit is represented as no corresponding point. 观察目标设计为在相邻的标识符之间共享,如图5b和5c所示。 Designed for observation target identifier shared between adjacent, as shown in Figure 5b, and 5c. 图5b示出标识符的正方形平铺16以及相应的最小视场193,该视场必须跨过两个标识符的对角线。 Figure 5b shows an identifier of a square tile 16 and the corresponding minimum field of 193, the field of view across the diagonal must be two identifiers. 图5c示出九个标识符的正方形平铺,为了示意包含全然相同的位元。 Figure 5c shows a square tiling of nine identifiers, to completely contain the same schematic bits.

利用(15, 7)里德-所罗门代码,将标识符的112个位元冗余编码以产生240个编码位元。 Use (15, 7) Reed - Solomon code, the 112-bit redundant coding identifier to generate 240 coded bits. 四个代码字在标识符内空间交织以增大区间误差的回复力。 Four code word in the identifier space to increase the restoring force interleaving interval error. 对于如上所述的一个16位标识符ID,这使得区域IID 达到92位。 As described above for a 16-bit identifier ID, which makes the region 92 reaches IID. 标识符的基于数据的点48设计为不和其邻接点交迭,从而标识符组不会产生类似目标的结构。 Identifier based on design data point 48 and its neighbor is no overlap, so that no group identifier structure similar objectives. 这也节约墨水。 It also saves ink. 因此观察目标允许检测标识符,所以不需要另外的目标。 Therefore, the observation target identifier allows detection, so no additional objectives. 如上所述进行标识符映象处理,除了略去步骤26和28。 Perform image processing identifier described above, in addition to omitting steps 26 and 28.

尽管标识符可以包含一个方位特征以明确标识符相对传感器的四个可能的方位,但是还可以在标识符数据内嵌入方位数据。 Although one orientation feature identifier may comprise an identifier to define the four possible orientations relative to the sensor, but may also embed orientation data in the identifier data. 例如,四个代码字可以布置为每个标识符方位包含一个放置在该方位上的一个代码字,如图5d所示,其中每个码元标有其代码字的编号(1-4)和码元在代码字内的位置(AO)。 For example, the four codewords can be arranged for each identifier comprises a bearing disposed on the orientation of a code word, shown in Figure 5d, wherein each symbol is labeled with the number of its codeword (1-4) and symbol position (AO) in the code word. 随后的标识符解码包括将每个方位上的一个代码字解码。 Then identifier decoding includes a code word for each azimuth decoding. 每个代码字既可以包括表示它是否是第一代码字的单个位元,也可以包括表示它是哪个代码字的两个位元。 Each codeword can either comprise a single bit indicating whether it is the first code word, indicating that it may also comprise two bits which code word. 后一种方法具有这样的优点,即如果只需要一个代码字的数据内容,则最多需要解码两个代码字以得到需要的数据。 The latter approach has the advantage that if only the data content of a code word, a maximum of two codewords need to be decoded to obtain the required data. 这可以是这种情况,如果不希望在一次笔划内改变区域ID并且从而仅在一个笔划的开始解码。 This may be the case, if you do not want to change the area ID within a stroke and is thus only a stroke start decoding. 在一次笔划内只需要包含标识符ID的代码。 In a stroke within the identifier ID need only contain code. 此外,由于检测元件的旋度在一次笔划内缓慢且可预见地变化,因此典型地只需要每桢解码一个代码字。 Further, since the rotation sensing element in a slow and predictable change in the stroke, and therefore typically need only decode a code word for each frame. 也可能完全不需要观察目标而是依赖于自动记录的的数据表示。 You may not need to observe the target entirely but rely on automatic recording of data representation. 在这种情况中,每个位元值(或多位元值)典型地由一个显式图示符表示,即没有位元值不是由图示符表示的。 In this case, each bit value (or bit value) is typically by an explicit glyph, ie no bit value is not represented by the glyph. 这确保数据网格被很好地填充,而且这样使得在数据采样时可靠地识别网格并且检测和随后校验其观察失真。 This ensures that the data grid is filled with good, and this makes the data grid sampling reliably identify and verify their testing and subsequent observation of distortion. 为了允许检测标识符边界,每个标识符数据必须包含一个标记符号,并且这些必须要冗余编码以允许可靠检测。 In order to allow the detection of identifiers border, each identifier data must contain a marker symbol, and these must be redundantly encoded to allow reliable detection. 这种标记符号的顶部和显式观察目标的顶部一样。 This tag symbol top and the top as the explicit target of observation. 这,1f方案利用相对网格被顶定位为不同点的点来表示不同的图示符并因而表示不同的多位元值 This, 1f program using the relative grid is positioned as the top point at different points to represent the different glyphs and thus represent a number of different cell values

对标识符解码形成了一个区域ID、 一个标识符ID、以及一个相关于标识符的笔变换。 Identifiers decoded to form a regional ID, an identifier ID, and a pen transform associated with the identifier. 在将标识符ID和相关于标识符的笔位置转换为在被标记区域内的一个绝对位置前,标识符在区域内的位置必须已知。 In the identifier ID and identifier associated with the pen position before converting an absolute position within the marked area, location identifiers in the region must be known. 这由一个标识符映象, 一个将被标记区域内的每个标识符ID映象到一个相应位置的函数给出。 This is indicated by an identifier mapping, an identifier ID will be marked on each image region corresponding to a given function of position. 一个标识符映象反映了用于用标识符平铺表面区域的方案,并且这可以根据表面类型变化。 A map identifier with an identifier for the program reflects the surface area of the tile, and this may be based on the type of surface changes. 当多个被标记区域共享同一个平铺方案和同一个标识符编号方案时,它们也共享同一个标识符映象。 When multiple marked area is shared with the program and when a tile with an identifier number scheme, they also share the same identifier map. 一个区域的标识符映象必须是可以通过区域ID检索的。 Identifier image of a region must be retrieved by area ID. 这样,给定一个区域ID、 一个标识符ID以及一个笔变换可以检索标识符映象,标识符ID可以转换为区域内的一个绝对标识符位置,以及相关于标识符的笔位置可以被叠加到标识符位置以产生区域内的绝对笔位置。 Thus, given a region ID, an identifier ID and a pen transform image can be retrieved identifier, the identifier ID can be converted to an absolute location area identifier, and the identifier associated with the location of the pen can be superimposed Identifier position to generate absolute pen location within the region.

标识符ID可以有一个有助于经由标识符映象转换的结构。 Identifier ID can have a map to help via identifier conversion structure. 根据它所在表面的类型,它可以是,例如,编码的笛卡儿坐标或者极坐标。 According to the type of surface on which it is, it may be, for example, the encoded Cartesian or polar coordinates. 标识符ID结构由标识符映象表示并已知于标识符映象,并且因此关联于不同标识符映象的标识符ID具有不同的结构。 Map identifier represented by the identifier ID and the structure is known in the identifier mapping, and thus different identifiers associated with the identifier ID mappings have different structures.

关心两种独特的表面编码方案,这两种方案都利用了本节上述的标识符结构。 Concern two distinct surface coding scheme, these two programs have taken advantage of this section above identifier structure. 优选的编码方案使用了已经描述过的"表示位置"的标识符。 The preferred coding scheme uses the already described "indicates the position of" identifier. 另一种编码方案使用了"表示对象"(或"表示功能")的标识符。 Another encoding scheme used "means that the object" (or "a functional") identifier.

一个表示位置的标识符包含一个标识符ID,当该标识符ID经由关联于被标记区域的标识符映象转换时,在区域内生成一个唯一的标识符位置。 An identifier indicating the location contains an identifier ID, when the identifier ID is converted via the associated tag identifier map area generates a unique identifier position in the region. 相关于标识符的笔的位置被叠加到这一标识符位置以产生笔在区域内的位置。 In relation to the position of the pen identifier is added to the identifier position to produce the pen position in the region. 这转而用于确定笔相对于关联于该区域的页面说明上的用户界面的位置。 This in turn is used to determine the position of the pen relative to the user interface associated with the region's page note. 不仅识别了用户界面本身,而且还识别了相对于该用户界面的位置。 Not only to identify the user interface itself, but also to identify the relative position of the user interface. 因此表示位置的标识符一般地支持捕捉在具体用户界面的区域内的绝对笔路径。 Thus an identifier indicating the position of general support in the region to capture specific user interface absolute pen path.

一个表示对象(或表示功能)的标识符包含一个标识符ID,该标识符ID直接识别关联于该区域(或者等同地, 一个功能)的页面说明上的用户界面。 Represents an object (or a functional) identifier contains an identifier ID, the identifier ID associated directly identify the area (or equivalently, a function) user interface page note. 用户界面的区域内的所有标识符识别该用户界面,使得它们全部一样并因此难于分辨。 All areas of the user interface identifier identifying the user interface, so that they are all the same, and it is difficult to distinguish. 因此,表示对象的标识符不支持捕捉绝对笔路径。 Therefore, an identifier that represents the object does not support the capture absolute pen path. 但是,它们支持捕捉相对笔路径。 However, they support the capture relative pen path. 只要位置采样频率超过二倍的标识符频率,则在一次笔划中从一个采样笔位置到下一个位置的位移就可以明确地确定。 More than twice as long as the location of the sampling frequency identifiers frequency, in a stroke of the pen from one sample to the next position to the displaced position can be clearly determined. 作为一种选择,网页笔101可以包含一对运动检测加速计,如我们较早的申请PCT/AU00/00565。 Alternatively, web 101 may comprise a pair of pen motion detection accelerometer, such as our earlier application PCT / AU00 / 00565.

现在说明本发明的以用于编码的电子墨水表面的笔类检测元件为形式的一个实施例。 Now explain to pen sensing element for electronic ink surface encoded in the form of an embodiment of the present invention. 下文将该检测元件简称为"笔"。 The sensing element hereinafter referred to as "pen."

电子墨水典型形式是基本上双稳态的单色或彩色点,它可以外部访问以便选择性地改变点的状态。 Electronic ink is typically in the form of a substantially bistable monochrome or color dots, which can selectively change the external access to state point. 一个单点的状态典型地通过施加合适极性的电场而改变。 State a single point, typically by applying an appropriate electric field polarity change. 尽管一些电子墨水是打印在一个表面上,但是其他的电子墨水实质上是加工在一个基层上,形成更加类似于"电子纸张"的物质。 Although some electronic ink is printed on a surface, but other electronic ink is essentially working on a grassroots level, to form a more similar to the "electronic paper" material. 这两种都视为包含于本发明的范围内。 Both are regarded as included within the scope of the present invention. 电子墨水以两种方式可变:它可以由含有合适的点寻址电极的打印机"打印"多次,并且它可以由含有合适的电极的写入(和/或擦除) 装置写入(和/或擦除)。 Electronic ink is variable in two ways: it can contain a suitable point by the printer address electrodes "Print" many times, and it can (and / or erased) device is written by writing the appropriate electrode containing (and / or erased).

一个编码的电子墨水表面是一种杂合物,它包含如上所述的不可变的标识符,以及可变的电子墨水。 Electronic ink is a surface of a coded heteroconjugate that contains immutable identifier as described above, and a variable electronic ink. 它还可以包含以常规方法打印在表面上的可见的图片信息。 It may also contain conventional methods to print on the surface of the visible image information.

一个编码的电子墨水表面的优点在于,如前所述,它可以通过使用包含一个合适的传感器的检测元件进行交互作用。 One advantage of electronic ink surface coding is that, as mentioned earlier, it can be contained through the use of a suitable sensor detecting elements interact.

本发明的该实施例中的笔特别设置为用以检测记录在一个表面上的用于向计算机系统发送指令的编码数据。 The embodiments of the present invention, the pen is set to detect particular record in a computer system used to send commands to the coded data on the surface. 这种编码数据包括用红外 Such coded data comprises an infrared

墨水打印在表面上的位置标识符。 Ink printed on the surface of the location identifier. 每个位置标识符包括打印的区域数据以及位置数据,其中区域数据表示了标识符所在区域形式的第一身份(例如,如果标识符打印在一页纸上,则该数据将识别这页纸), 而位置数据表示了区域内标识符形式的第二身份。 Each location area identifier includes print data and the position data, wherein the data region represents a first location identifier in the form of identity (e.g., if the identifier is printed on a page, which identifies the data sheet) and the position data represents the area identifier in the form of a second identity. 位置数据还包括目标结构,该目标结构能够计算笔相对于其上打印有标识符的表面的三维方位(例如,相对于表面平铺)。 Location data structure further comprises a target, the target structure can be calculated relative to the pen on the printed surface of the three-dimensional position identifier (e.g., with respect to the surface of the tile). 标识符可以包括各种控制数据。 Identifier may include various control data. 笔101设置为确定映象传感器32的位置,并且从而通过以红外线频谱映象临近笔尖的表面的一个区域来确定笔尖(铁笔尖121或笔尖119)的位置。 Pen 101 is provided to determine the position of the image sensor 32, and thus through a region adjacent to the infrared spectral image of the surface to determine the nib tip (iron pen nib 121 or 119) in position. 它记录来自最近的位置标识符的位置数据,并且设置为利用光学件135和控制器芯片134计算映象传感器32并且从而笔尖121或119距位置标识符的距,惑。 It records the location data from the most recent position of the identifier, and is set to use an optical element 135 and controller chip 134 to calculate the image sensor 32 and thereby nib 121 or 119 from the location identifier distance, confusion. 控制器芯片134由在映象标识符上发现的观察失真计算笔的方位以及笔尖到标识符的距离。 The controller chip 134 by the observation identifiers found in the image distortion calculation pen nib azimuth and distance to the identifier. 来自位置标识符的控制数据包括指令笔101启动其"激活区"LED (这实际上是三色LED116的一种模式,当笔根据控制数据确定被映象的区域是"激活区"时,该LED变成黄色)的控制位元。 Control data from the location identifier of the pen 101 includes an instruction to start its "active region" LED (which is actually a three-color pattern LED116 when the pen is determined based on the control data area is mapped is the "active region", the LED turns yellow) control bits. 这样,如果笔的用户可见地反馈当笔101跨过按钮或超级链接时按钮或超级链接被激活,则表面上对应于按钮或超级链接的激活区的区域可以被编码以激活该LED。 Thus, if the user of the pen visible feedback when the pen 101 across the button or hyperlink button or hyperlink is activated, the upper surface of the area corresponding to the button or hyperlink activation zone can be coded to activate the LED. 控制数据还可以指令笔101捕捉连续的笔作用力读数。 Control data can also command pen 101 pen force to capture continuous readings. 这样表面上对应于签名输入区的区域可以被编码以捕捉连续的笔101作用力。 This corresponds to the signature on the surface area of the input area can be encoded pen 101 to capture continuous force. 笔101相对于表面的运动可以包括一系列笔划。 T 101 with respect to the motion of the surface may include a series of strokes. 一个笔划由以时间表示的笔101在表面上的位置的一个序列组成,由下笔开始并由随后的提笔完成。 A stroke consists of a sequence of time indicated by the pen 101 on the surface composition of the position, the write is completed by the start of the next pen. 注意笔作用力可以理解为相对于阈值来表示笔是"上" 还是"下",以及可理解为一个连续值,例如当笔捕捉签名时。 Note that the pen can be understood as a force with respect to a threshold value representing the pen is "up" or "down", and understood as a continuous value, such as when the pen signature capture. 所捕捉的笔划的序列下文中将称之为"数字墨水"。 It will be referred to as "digital ink" captured the stroke sequence below. 数字墨水可以用于计算机系统以形成图画和笔迹的数字互换,联机识别笔迹,以及联机验证笔迹的基础。 Digital interchangeable digital ink can be used to form a picture of a computer system and handwriting, online handwriting recognition, and basic online validation handwriting. 利用RF芯片133和天线112,笔101可以将数字墨水数据(为了安全它被加密并且为了有效传送它被打包)传送到计算机系统。 The use of RF chip 133 and an antenna 112, 101 may be digital ink pen data (which is encrypted for security and packaged for efficient delivery of it) to a computer system. 当笔处于接收器的范围内时,当形成数字墨水数据时它被传送。 When the pen is in the range of the receiver, the digital ink data formed when it is transmitted. 当笔移出范围时,数字墨水数据在笔101内缓冲(笔101电路中包括一个缓冲器,设置为存储笔在表面上运动的数字墨水数据大约12分钟),并且可以以后传送。 When the pen out of range, digital ink data is buffered within the pen 101 (the pen 101 circuitry includes a buffer to store digital ink data of the pen motion on the surface of about 12 minutes), and can be transmitted later. 笔101还包括一个状态改变装置,其形式为电场发生器,该状态改变装置用于当笔101相对表面运动时改变表面的电子墨水的状态。 Pen 101 also includes a state changing means, in the form of electric field generator, the changing means for changing the state of the surface when the relative movement of the pen 101 when the state of the surface of the electronic ink. 可以启动电场发生器,其中通过状态改变装置发生电子墨水的状态改变,或者不启动,其中利用任何合适的检测装置,例如作用力传感器, 不发生通过状态改变装置的状态改变。 Electric field generator can be started, wherein the status change status by means of electronic ink changes occur, or does not start, wherein the detecting using any suitable means, such as force sensors, no state change occurs by means of the state change. 作用力传感器可以设置为当装置和表面之间的相对作用力超过预定值时启动或不启动电场发生器。 The force sensor can be set to start or not start the electric field generator exceeds a predetermined value when the relative force between the device and the surface. 作用力传感器可以和光学传感器一样或者独立于光学传感器,其中该光学传感器用于检测提笔和下笔状态和/或如上所述由用户施加到表面上的作用力的程度。 Force sensors and optical sensors in the same or a separate optical sensor, wherein the optical sensor for detecting the pen and the pen down state and / or the degree of force applied by the user on the surface of the above. 电场发生器的启动可以通过将启动或不启动标记施加到表面上来控制。 The electric field generator may be started by the start or not start up the control marker applied to the surface. 为了使电场发生器可以启动或不启动,必须要激活电场发生器。 In order to make the electric field generator can start or does not start, the electric field generator must be activated. 该标记可以被笔的检测装置检测到,并且用于启动或不启动电场发生器。 The marker pen can be detected by detecting means, and used to start or not start electric field generator. 启动还可以由和笔通信的计算系统控制,并且可以基于表面说明, 或者由区域ID识别的和笔交互的表面的区域,其中区域ID由笔从表面上的位置标识符检测并且和计算系统通信。 You can also start from the pen of communication and computing systems control, and may be based on surface description, or the surface of the pen and regional interaction identified by the area ID, wherein the area by the pen ID and communications and computing systems from the position on the surface of the tag detector . 当启动时,允许电场发生器改变打印在表面上的电子墨水的状态,不启动时,不允许电场发生器改变打印在表面上的电子墨水的状态。 When activated, it allows the state to change the electric field generator is printed on the surface of the electronic ink is not activated, the electric field generator is not allowed to change the status of the print on the surface of electronic ink. 启动或不启动标记可以包含于位置标识符中作为一系列位元,这些位元表示由标识符占用的区域的映象,并且每个位元表示了一个区域或子区域是可以修改还是不能修改。 Start or not start marker can be contained in a series of bits as the location identifier, which indicates the bit map area occupied by the identifier, and each bit represents a region or sub-region can not be changed or modified . 可选地,启动或不启动标记可以独立于位置标识符。 Alternatively, start or not start flag independently of the location identifier. 还可选地,如上面暗示的,启动或不启动信息可以是由计算系统维持的表面说明(例如页面说明)的一部分。 Still alternatively, as implied above, start or not start some information may be maintained by surface Description computing system (e.g., page description) is. 以此方式,表面上的特定区域可以被标记从而指出表面的可标记区域、不可标记区域、可擦除区域或不可擦除区域。 In this manner, a specific area on the surface can be marked so indicated markable surface area, non-mark area, erasable or non-erasable area region. 电场发生器可以放置在笔的一个纵端并且设置为具有两种操作模式,即,将电子墨水的状态改变为第一状态(例如"被标记")的第一模式,以及电场发生器的第二模式用于,例J将电子墨水的状态改变为第二状态(即"空"或"被擦除")。 The first mode of a first electric field generator may be placed at one longitudinal end of the pen and arranged to have two modes of operation, i.e., the state of the electronic ink changes to a first state (e.g., "labeled"), and an electric field generator Second mode is used, for example, the state of the electronic ink J was changed to a second state (i.e., "empty" or "erased"). 电场发生器可以包括一个或多个电极,具有相同的或者相反的极性。 An electric field generator may comprise one or more electrodes, with the same or opposite polarity. 在一种配置中,如图13所示,笔内的电极500和表面介质504 的导电层502交互作用以产生基本直交于表面的电场506。 In one configuration, shown in Figure 13, the pen 500 and the inner surface electrode 504 of a conductive medium layer 502 interact to generate an electric field substantially perpendicular to the surface 506. 该电场用于将电子墨水层508内的电子墨水颗粒和电场对齐,从而控制电子墨水并从而该表面的可见的版面。 The field for the electronic ink particles of electronic ink layer 508 and the electric field aligned within to control electronic ink and thus visible layout of the surface. 在标记模式中,电极相对于导电基层转换到一个极性,而在擦除模式中,电极转换到相反的极性。 In mark mode, a conductive substrate electrode with respect to a polarity conversion, whereas in the erase mode, switching to an opposite polarity electrode. 在另一种配置中,相反极性的电极被设置在笔中以产生穿过表面的电场,并且它的密度在所需要的方向上大于相反的方向。 In another arrangement, the electrodes of opposite polarity are disposed in the pen across the surface to generate an electric field, and its density in the desired direction than in the opposite direction. 电极可以包含在金属端头件114、盖107、或铁笔尖121中。 The electrodes may be included in the metal end pieces 114, cover 107, 121 or iron tip. 在另一个实施例中,标记和擦除电场发生器可以设置在笔的相反的纵端上。 In another embodiment, the marker and erase electric field generator may be disposed on opposite longitudinal ends of the pen. 当然,这种布置下,在笔的每一端都需要标识符传感器。 Of course, under this arrangement, at each end of the pen sensor needs an identifier. 通过在表面上打印电子墨水点和永久墨水点而将信息施加到表面上,其中当打印在表面上时电子墨水点肉眼可见或不可见,永久墨水点例如是基于颜料的彩色墨水点或基于染料的墨水点。 Electronic ink by printing ink dot and permanent point on the surface and applying the information to the surface, which, when printed on the surface of the electronic ink dot visible or invisible, permanent ink spot color ink, for example, based on point-based pigment or dye The ink dot. 电子墨水点可以如上所述做的可以修改,而永久墨水点保持不可修改。 Electronic ink dot can be done as described above may be modified, but can not be modified to maintain permanent ink dot. 这使得由用户通过改变电子墨水的状态而在表面上所做的标记可以修改而不影响不可修改的预先打印的信息。 This allows the user to change the state of the electronic ink mark made on the surface can be modified without affecting the pre-printed information can not be modified. 下文将更加详细地说明笔的各种操作。 Hereinafter will be described in greater detail the various operations of the pen. 如上所述,控制器芯片134安装在笔101内的第二柔性PCB129 上。 A second flexible

当笔101不和表面接触时一个不启动周期后控制器ASIC 134进入静止状态。 When the pen after contact with the surface 101 does not start a cycle controller ASIC 134 enters a quiescent state. 它包含一个专用电路150,以监测作用力传感器光电二极管144并且当发生下笔事件时通过电源管理器151唤醒fc制器134。 It contains a dedicated circuit 150 to monitor the force sensor photodiode 144 and 151 when the event occurs Wake write power manager system 134 fc.

无线电发送器通信频率为通常用于无绳电话的未授权的卯OMHz 频段,或者可选地为2.4GHz的工业、科学和医疗频段,并且利用频率跳跃和冲突检出以提供抗扰的通信。 Mao OMHz unauthorized communication frequency band radio transmitter is typically used in cordless phones, or alternatively for the 2.4GHz industrial, scientific and medical band, and the use of frequency hopping and conflict detection to provide immunity communications.

如上所述,笔101的光学系统由一个模制的光学件135实施。 As described above, the optical system 101 consists of a pen molded optical member 135 embodiment. 由光学件135实施的光学系统示意性地表示在图10中。 The optical system is composed of an optical member 135 of the embodiment is schematically shown in FIG. 10. 该光学系统包括一个第一透镜157用于将来自红外线LED131的射线聚焦, 一个镜子158, 一个射束分裂器159, 一个物镜160以及一个第二透镜161 用于将一个映象聚焦到映象传感器132上。 The optical system comprises a first lens 157 for focusing rays from the infrared LED131, a mirror 158, a beam splitter 159, an objective lens 160 and the image sensor 161 and a second lens for focusing an image 132. 近轴光线162表示光学路径。 Paraxial ray 162 indicates an optical path.

光学路径设计为将所需要的平铺范围内的和视场锥192贯穿相交的被映象表面的那一部分193的一个清晰映象传送到映象传感器132。 The optical path is designed to and within the field of view cone 192 needed through intersecting tile range is mapped surface portion 193 that a clear image is transmitted to the image sensor 132. 主要的聚焦部件是物镜160。 The main focus of the objective lens 160 is a member. 这也反过来用于将来自IR照明LED131 的光线投射到视场内的表面上。 This in turn is used to light from IR illumination LED131 projected onto the surface of the field of view. 因为不可能将映象传感器132和IR LED131都放置在物体的焦点上,所以使用一个射束分裂器159来分裂路径,并且在每个路径上的传播透镜157和161分别提供了在映象传感器132和IR LED131上的再次聚焦。 Because it is impossible to image sensor 132 and IR LED131 are placed at the focal point of the object, so use a beam splitter 159 to split path, and spread lens on each path 157 and 161 are provided in the image sensor Focus again on 132 and IR LED131. 这也允许将不同的装置设置在这两个路径上。 It also allows different devices provided on both paths.

映象传感器132的边缘用做捕捉视场的视场光阑,并且捕捉路径设计为使得最终的对象空间角度视场符合需要(即对于本实施例来说是20度以下一一参见下文)。 The edge of the image sensor 132 is used as the field diaphragm to capture the field of view, and is designed to capture the path so that the final field of view angle meet the needs of the target space (that is, for the present embodiment is 20 degrees or less one see below). 照明路径设计为产生和捕捉路径一样的对象空间视场,从而照明用最大能量和均匀性填充对象空间视场。 Lighting the path designed to generate and capture the same target path field space, lighting uniformity with maximum energy and space filling an object field of view.

IR LED131由桢捕捉同步滤波。 IR LED131 captured by the frame synchronization filtering. 聚焦照明的使用允许短的暴光时间和小的光圈。 Focus Use lighting allows a short exposure time and small aperture. 短的曝光时间防止运动模糊,从而允许在笔移动过程中捕捉位置标识符数据。 Short exposure times prevent motion blur, allowing the capture location identifier data in the pen movement. 小的光圈允许由平铺引起的表面深度的整个范围具有足够的视场深度。 Small aperture allows the entire range of depth from the surface of the tile due to having a sufficient depth of field. 为此目的,捕捉路径包括一个显式孔径光阑。 Object, capturing an explicit path including through the aperture stop.

因为映象传感器132在频谱的整个可见部分以及近红外部分具有很强的响应,因而在捕捉路径上有一个红外线过滤器163放置在它前面,从而它可以捕捉表面上标识符数据的清晰映象,而不受表面上其他图象的干涉,其中这些其他图象可以用透明于近红外线的墨水打印。 Because the image sensor 132 has a strong response throughout the visible and near-infrared part of the spectrum portion, so that there is a path in the capture infrared filter 163 placed in front of it, so that it can capture an identifier on a surface of a clear image data in the near-infrared ink printing on the surface without the interference of other images, wherein the other image can be transparent.

当笔101的铁笔尖121或笔尖119接触表面时,笔101以100Hz 的频率确定其相对于表面的位置和方位以允许精确识别笔迹(参见Tappert, C, CY Suen和T Wakahara的文章"联机识别笔迹技术的现状"(The State of the Art in On-Line Hand Writing Recognition) , IEEE 关于图样分析和机器智能(Pattern Analysis and Machine Intelligence) 的学报,第12巻,第8号,19卯年8月,其内容包含于本文以做参考)。 When the iron tip of the pen nib 119 101 121 or contact surface, the pen 101 at a frequency of 100Hz to determine its position and orientation relative to the surface to allow for accurate handwriting recognition (see Tappert, C, CY Suen and T Wakahara article "Online Recognition Status "handwriting technology (The State of the Art in On-Line Hand Writing Recognition) IEEE Journal of pattern analysis and machine intelligence on (Pattern Analysis and Machine Intelligence), the first Volume 12, No. 8, August 19 d , the contents contained in the paper for reference). 作用力传感器光电二极管144用于表示笔是"上"还是"下" 的相对阈值。 The force sensor photodiode 144 is used to indicate the pen "up" or "down" relative threshold. 如上所述,作用力也可以作为连续值捕捉,以便允许验证签名的全部动力特性。 As described above, the force can be captured as a continuous value to allow all dynamic characteristics to verify the signature.

通过以红外线频谱映象接近笔尖119、 121的表面的区域,笔101 确定其笔尖119、 121在表面上的位置和方位。 Infrared spectral image by approaching the tip 119, a surface area of 121, 101 to determine the pen nib 119, 121 on the surface of the position and orientation. 它解码最近的标识符数据并且根据所发现的被映象标识符上的观察失真以及已知的笔光学件135的几何结构计算笔尖119、 121相对位置标识符的位置。 It recently decoded identifier data and calculates the tip 119, position 121 in accordance with the relative position of the identifier observation geometry distortion is mapped identifier found on the well known pen optics 135. 尽管标识符的位置分辨率可能很低,但是调整后的位置分辨率非常高,可以很容易地超过精确识别笔迹所要求的200dpi的分辨率(参见以上参 Although the position resolution identifier may be low, but the adjusted position resolution is very high, it can easily exceed the required precise handwriting recognition 200dpi resolution (see above reference

考文件)。 Test files).

笔101相对于表面的运动作为一系列笔划被捕捉。 T 101 with respect to the motion of the surface is captured as a series of strokes. 一个笔划由以 In a stroke by the

时间表示的笔在表面上的位置的一个序列组成,由下笔开始并由随后 A sequence of time represented by the position of the pen on the surface composition, followed by the write start

的提笔完成。 The pen is completed. 当区域ID改变时,即正常情况下在笔划开始时,笔划还用表面的区域ID标记。 When the area ID change, that under normal circumstances, when the stroke began, also with a surface area of stroke ID tag. 如上所述,每个位置标识符包括表示其在表面上的位置的数据和表示标识符所在的表面区域的区域数据。 As described above, each position identifier comprises express its position on the surface data representing a surface area where the data identifier area.

笔还检测并解码表示在表面上的任何标记,并且响应标记的检测而视情况使得电场发生器能够标记表面或者将标记从表面擦除,或者不能进行标记和擦除。 Pen also detect and decode represent any marks on the surface, and in response to a detectable label and the electric field generator as the case may be able to mark the surface or erase marker from the surface, or can not be marked and erased.

图11是表示笔101内的位置标识符和笔划过程的流程图。 FIG 11 is a flowchart showing the process of location identifiers and pen strokes 101. 当笔101处于提笔状态时,笔控制器134连续监测作用力传感器光电二极管144的下笔条件(步骤164)。 When the pen 101 is in the state pen, pen controller 134 continuously monitoring the force sensor photodiode 144 write condition (step 164). 当笔处于下笔状态时,笔控制器134 连续捕捉165、 166并解码167表面的位置标识符的标识符数据,推出笔101相对于表面的位置和方位168,并且将位置数据添加到当前笔划数据(包括标识符数据和其他信息,例如作用力,如果作用力是被连续监测的话)。 When the pen in the pen down state, the pen controller 134 continuously captured 165, 166 and 167 surface decoded identifier data location identifier to launch pen 101 relative to the position and orientation of the surface 168, and to add location data to the current stroke data (including data identifiers and other information, such as the force, if the force is continuously monitored it). 当发生提笔事件时,笔控制器134加密170笔划数据并且通过RF芯片133和天线112将笔划数据传送171到计算系统。 When an event occurs pen, pen stroke data controller 134 and encrypted 170 112 171 stroke data transfer to the computer system 133 through RF chip and antenna. 注意笔采样笔尖作用力172以便确定笔划是否已经完成173并且还确定是否开始一个新的笔划174。 Note that the pen nib force sample 172 to determine whether the stroke has been completed 173 and also determines whether to start a new stroke 174.

如果是相当快速的8位乘法,则笔活动时处理算法占用80%的处理器时间。 If it is quite fast 8-bit multiply, then the pen is active processing algorithms occupied 80 percent of processor time.

如果笔脱离所要传送的计算系统的范围,则它将数字墨水缓冲在其内存里。 If the pen to be transferred out of the scope of a computing system, it will be buffered digital ink in its memory. 当它下一次处于计算系统的范围内时,它将传送任何被缓冲的数字墨水。 When it next time in the range of computing systems, it will transmit any buffered digital ink. 当笔的内存占满时笔停止捕捉数字墨水并当用户试图用笔101写入时闪亮错误LED。 When the pen's memory is full stop capturing digital ink pen and the pen when the user attempts to write when 101 Flashing Error LED.

图12是从笔101传送到计算系统的原始数字墨水结构的示意图。 12 is a schematic diagram of the transmission from the pen computing system 101 to the original structure of the digital ink. 当笔101脱机工作时缓冲在笔101内的数字墨水以与传送到系统的数 When the pen 101 working offline buffering in the digital ink pen 101 is transmitted to the system with the number of

统获得的笔ID、笔尖ID175、当前绝对时间176、以及最后绝对时间。 EC obtained pen ID, nib ID175, the current absolute time 176, and finally the absolute time. 这允许系统以笔的时钟计算和漂移并且从而时间漂移任何从笔101接收的数字墨水。 This allows the system clock to pen computing time drift and drift and thus received from any digital ink pen 101. 随后笔101将其实时时钟和系统的精确实时时钟保持同步。 Then the pen 101 will in fact accurate real-time clock and system clock to keep pace. 笔ID使得当有多个笔运行于计算系统时计算系统可以识别笔。 Pen ID so that when there is more than one pen computing system running at the time of the calculation system can recognize the pen. 在例如利用笔来识别笔的所有者,并且以特别直接的方式和该所有者交互作用的系统中笔ID是非常重要的。 For example, use a pen to identify the owner of the pen, and in a particularly direct way and the owner of the pen ID system interaction is very important. 在其他实施例中这可以是不必要的。 In other embodiments, it may not be necessary. 笔尖ID使得计算系统可以识别哪个笔尖,铁笔尖121或墨水笔筒笔尖119,正在使用。 Nib ID allows the computing system can identify which nib, iron nib ink pen nib 121 or 119, is being used. 计算系统可以根据正在使用哪个笔尖而改变其操作。 The computing system according to which the tip is used to change its operation. 例如,如果正在使用墨水笔筒笔尖119,计算系统会延迟产生反馈输出,因为及时反馈由标在表面上的墨水标记提供。 For example, if you are using an ink pen nib 119, a computing system delays generating a feedback output, because timely feedback is provided by standard ink mark on the surface. 当正在使用铁笔尖121时,计算系统会生成及时反馈输出。 When you are using the iron tip 121, a computing system generates timely feedback output.

在笔划开始时,笔控制器134记录从通知给系统的最后绝对时间开始经过的时间。 At the beginning of the stroke, the pen controller 134 records from the notification system to the last absolute time elapsed time. 对于每个笔101位置177,笔划过程中控制器134 记录笔尖119、 121从当前标识符的x和y偏移,笔101的x、 y和z 旋度,以及笔尖作用力。 For each position of the pen 101 177, the process controller 134 records the stroke tip 119, 121 from the current x and y offset of the identifier, the pen 101 x, y, z, and rotation, and the tip forces. 如果标识符ID发生改变则只记录标识符ID (识别标识符位置的数据)。 If the identifier ID changes only the record identifier ID (identification identifier location data). 由于标识符频率稍微小于典型的位置采样频率,因此标识符ID对于许多连续的笔101位置是恒定的,并且如果笔划很短,对于整个笔划来说也可以是恒定的。 Since the identifier frequency slightly less than the typical position of the sampling frequency, and therefore the identifier ID 101 for many successive pen position is constant, and if the stroke is very short, it may be for the entire stroke constant.

由于笔101以100Hz采样其位置和方位,因此在一个笔划中的笔101位置是以100Hz隐含地计时并且不需要显式的时间表示。 Since the pen 101 to 100Hz sampling its position and orientation, so in a stroke of the pen 101 positions is 100Hz implied timing and no explicit time representation. 如果笔101未能计算笔101位置,例如由于它未能解码标识符,它仍然必须记录笔101位置以保持隐含计时。 If the pen 101 pen 101 positions could not be calculated, for example, because it fails to decode identifier, it must still be the position of the stylus 101 in order to maintain the implied timing. 因此它将位置记录为未知179,如果必要,允许计算系统以后从相邻的采样插入位置。 So it is unknown location record 179, if necessary, after allowing the computing system from a position adjacent to the sample insertion.

由于笔划的32位时间偏移具有有限的范围(即49.7天),因此笔101可选地记录一个笔划的绝对时间176。 Since the stroke of 32 time offset has a limited range (ie 49.7 days), so the pen 101 optionally an absolute time record of 176 strokes. 这成为绝对时间,相对于该绝对时间测量以后的笔划时间偏移。 This is an absolute time, with respect to the measurement of absolute time after time shift stroke.

由于标识符ID对于许多连续的笔划是恒定的,因此如果标识符ID 发生改变笔只记录标识符ID180。 Since the identifier ID for many successive strokes it is constant, so if you change the identifier ID pen only record identifier ID180. 这成为隐含地关联于以后的笔位置的标识符ID。 This becomes implicitly associated with the pen position after an identifier ID.

由于用户可能在一个笔划和下一个笔划之间改变笔尖119、 121, 因此笔101可选地记录一个笔划的笔尖ID。 Since the user may change the nib 119, 121 between one stroke and the next stroke, so the pen 101 optionally record a stroke of the pen tip ID. 这成为隐含地关联于以后的笔划的笔尖ID。 This becomes implicitly associated with the subsequent stroke nib ID.

一个笔划的每个成分都有一个熵编码的前缀。 A stroke of each component has a prefix entropy coding. 一个1秒时间段内的10毫米笔划跨过两个或三个标识符,包含100个位置采样,并且因而有大约5500位的大小。 A one second period of 10 mm strokes across two or three identifier containing 100 location samples, and thus the size of about 5500. 因此联机连续捕捉数字墨水需要大约5.5Kbps的最大传送速度,而脱机连续捕捉数字墨水需要大约每分钟40Kbytes的缓冲内存。 Therefore, the continuous line of digital ink capture the maximum transmission speed of about 5.5Kbps needs, while offline successive captures digital ink takes about 40Kbytes per minute buffer memory. 因此笔的512KB的DRAM 148可以保持12分钟以上的连续数字墨水。 Thus pen 512KB of DRAM 148 can be maintained 12 minutes or more consecutive digital ink. 时间、区域和笔尖的变化很少发生因而它们对所需要得传送速度和缓冲内存得影响忽略不计。 Changes in time, regional and tip rarely occurs so they have to transfer to the desired speed and buffer memory effect was negligible. 笔101位置得附加压縮可以进一步降低对传送速度和缓冲内存的要求。 101 pen position to give additional compression can further reduce the transmission speed and buffer memory requirements.

每个原始笔划在传送到计算系统之前利用Triple-DES算法加密(该算法参见Schneier, B的"实用密码技术"(Applied Cryptography), 第二版,Wiley出版社1996年,其内容包含于本文以做参考)。 Each original stroke prior to transmission to the computing system uses Triple-DES encryption algorithm (the algorithm see Schneier, B "A Practical cryptography" (Applied Cryptography), Second Edition, Wiley Press, 1996, the contents contained in the paper for reference). 为此目的笔和计算系统在一个规则的基础上交换话路密钥。 Purpose pen and computing systems on a regular basis to exchange the session key for this. 基于每个加密位元50个循环的保守估计, 一个一秒5500位笔划的加密消耗处理器时间的0.7%。 Each bit encryption based on a conservative estimate of 50 cycles a second stroke of 5500 encryption processor time consumption of 0.7%. 在第一个可选实施例中,编码数据表示了一个身份,该身份是识别基层的数据。 In a first alternative embodiment, the encoded data shows an identity, that identity is to identify the basic level of data. 这使得笔101识别基层,例如基层是否是一种特别类型的文件或者基层是否构成了另一个物体的一部分。 This makes the pen 101 recognizes the grassroots level, for example, is whether the grassroots whether a special type of file or grassroots forms part of another object. 当然,由于该实施例中标识符表示表面的属性而不是标识符相对于表面的位置,因此需要单独的装置用于检测装置相对于表面的运动。 Of course, since in this embodiment the identifier represents the surface properties rather than the position identifier relative to the surface, and therefore requires a separate means for detecting relative movement of the surface of the device.

在第二个可选实施例中,编码数据表示了一个身份,该身份是表示标识符类型的数据。 In a second alternative embodiment, the encoded data shows an identity, that identity is an identifier type of data. 笔101可以识别标识符是否表示一个关心的对象而不是表面上的位置。 Pen 101 can identify whether the identifier indicates the position of an object on a concern rather than surface. 例如,如果标识符表示一个对象并且对应于一个用户接口输入部件(例如一个按钮),则该标识符可以直接识别输入部件。 For example, if the identifier represents an object and corresponds to a user interface input element (e.g. a button), the identifier may directly identify the input member.

用于可选实施例的一种合适的独立的运动检测装置包括一对安装 An alternative embodiment for a suitable independent motion detection means includes a pair of mounting

在垂直于笔101轴线的平面内的直交的加速计190。 In a plane perpendicular to the axis of the pen 101 190 orthogonal accelerometers. 在图10和9中以虚线表示加速计190。 10 and in FIG. 9, the accelerometer 190 shown in phantom.

加速计使得笔101的该实施例能够检测运动而不参考表面标识符,允许以较低比例采样标识符。 Accelerometers so that the pen 101 according to this embodiment is capable of detecting motion without reference to surface identifier, allowing a lower ratio of sample identifiers.

由加速计在x和y方向上测量的加速度相对于时间积分得到瞬时速度和位置。 By the accelerometer in the x and y directions with respect to the measured acceleration to give the time integral of the instantaneous velocity and position.

由于不知道笔划的开始位置,因此只计算笔划内的相对位置。 Because they do not know the beginning of the stroke, it only calculates the relative position within the stroke. 尽管位置积分在所检测到的加速度内累计误差,但是加速计典型低具有高精度,并且其上累计误差的笔划的时间周期很短。 Although the position of integration within the detected acceleration cumulative error, but the accelerometer typically low with high precision, and the time period on which the cumulative error of the stroke is short.

可以提供另外一种运动检测装置,而不提供用于检测相对表面的运动的加速计。 It may provide another motion detecting means for detecting a relative surface without providing motion accelerometer. 这种装置包括含有一个光学传感器的运动检测装置, 其中该光学传感器与表面协作以产生表示光学传感器相对于表面的运动的信号;含有至少两个触点的运动检测装置,其中触点设置为与表面接触并检测两个正交方向上的运动;或者其他任何合适的用于检测相对一个表面的运动的运动检测装置。 Such apparatus comprises a motion detecting means comprises an optical sensor, wherein the optical sensor and the surface cooperate to generate a signal indicative of the movement of the surface relative to the optical sensor; motion detecting means comprises at least two contacts, wherein the contact set and surface contact and detecting movement in two orthogonal directions; or any other suitable surface for detecting the relative motion of a motion detector.
