Description
Technical field
The present invention relates to data Technique of Input Process field, be specifically related to a kind of method and apparatus that receives user's input of realizing on equipment.
Background technology
At present, mobile computing device, is widely used such as mobile phone, handheld computer and personal digital assistant (PDA), and increasing equipment has all started touch-screen to be provided and to receive the information that user inputs by touch-screen.And some equipment provide dummy keyboard by touch-screen, dummy keyboard is the keyboard that demonstrates a down-scaled version on touch-screen.Then, user can click virtual key corresponding on soft keyboard by input pen or finger, and equipment, by detecting the clicking operation of user on soft keyboard, is then inputted corresponding character.
For example, the portable handheld device (as mobile phone, PDA etc.) of small volume, in order to ensure its portability, often cannot use physical keyboard, only use virtual soft keyboard (onscreen soft qwertykeyboard), as shown in Figure 1, this soft keyboard and conventional qwerty keyboard layout are similar, and qwerty keyboard layout gains the name with the order of the alphabet key of keyboard upper left-hand part.Because the screen area of the touch-screen of portable handheld device is limited, therefore button area and the button interval of dummy keyboard are all less, make this dummy keyboard be difficult to operation, easily often there will be the situation of maloperation.
In prior art, on the dummy keyboard of touch-screen, click virtual key by user, input respective symbols, an only corresponding character of a virtual key.The present embodiment provides a kind of new improving mechanism, at least two characters of a virtual key correspondence, user can also continue to slide to different directions after click virtual key, and equipment, according to reference position and the glide direction of the gesture of user's input, is determined the corresponding character of this gesture.Concrete glide direction, can calculate according to the position coordinates of the starting point of gesture and terminal.Owing to adopting a virtual key corresponding at least two characters, therefore in the embodiment of the present invention, the virtual key on dummy keyboard at least can reduce over half, thereby can on limited display screen, increase area and the button interval of virtual key as far as possible, this dummy keyboard is more easily operated, reduce the situation that occurs maloperation.
As shown in Figure 3, receive the method for touch-screen input described in the present embodiment, be applied on the equipment that includes touch-screen, said method comprising the steps of:
Step 31, at least comprises the dummy keyboard of a virtual key in described touch screen display.
Here, each virtual key of touch screen display is exactly an input area.
Step 32, described equipment receives user by the first gesture of inputting on touch-screen;
Step 33, obtains starting point and the end point of described first gesture, calculates the first distance between described end point and described starting point, judges that whether described the first distance is less than predetermined threshold, and export a judged result.
Here according to the coordinate of described end point and described starting point, can calculate described the first distance.Described the first distance is the sliding distance of described first gesture on described touch-screen.For example, to point input gesture as example, starting point is the point of finger contact touch-screen while starting to input gesture, and when end point is gesture end of input, finger leaves the point of touch-screen.Adopt other input mode, as rocking bar, nine Xiang Jian etc., also adopt similar decision procedure.
At the sliding distance of described gesture hour, the present embodiment judges that first gesture is only to have clicked certain virtual key; In the time that sliding distance is larger, this present embodiment judges that first gesture not only clicked certain virtual key, and slides with certain direction.Described predetermined threshold specifically can be set according to the size of virtual key on touch-screen.
Step 34, in the time that described judged result indicates described the first distance to be less than described predetermined threshold, described equipment, according to first virtual key at the corresponding relation between predefined virtual key and character and described starting point place, is determined first character corresponding with described the first virtual key input.
Here, set up in advance the corresponding relation between each virtual key (being input area) and character on the described equipment of the present embodiment, different virtual keys is corresponding to different characters.When first gesture is only, while clicking certain virtual key, just to input the character that this virtual key is corresponding.
Step 35, in the time that described judged result indicates described the first distance to be not less than described predetermined threshold, according to the corresponding relation between gesture and the character of different directions under predefined each virtual key and first virtual key at described starting point place and the first direction of described first gesture, determine second character corresponding with described the first virtual key and first direction input.
Here, also set up in advance the corresponding relation between gesture and the character of different directions under each virtual key on the described equipment of the present embodiment, under same virtual key, the gesture of different directions is corresponding to different characters.Click certain virtual key and slide with certain direction when first gesture, now inputting the corresponding character of gesture of this direction under this virtual key.Direction can be determined by the position coordinates of starting point and end point.
In the present embodiment, user's finger or input pen gesture of every input on virtual key have just completed once input, a character of each input operation input.Each gesture only need detect starting point and the terminal of this gesture, and the angle of the line of origin-to-destination is exactly glide direction.
The present embodiment is described further to 26 English alphabets of z as example taking input a below.Consider alphabetical quantity, the width of perpendicular version handheld device, the factor such as size and finger contact area of touch-screen, normally 3 times of left and right of finger contact area of width of the touch-screen of perpendicular version handheld device, therefore it is most suitable adopting 3 virtual keys, on each virtual key, can arrange 9 characters according to the mode of 3 row × 3 row; And a～z totally 26 English alphabets be distributed on 3 virtual keys, each virtual key is assigned with 9 characters, altogether 27 characters increase a non-alphabetic character for this reason again, as the carriage return character "
", space character or an arbitrary punctuation mark.Amount to like this 27 characters, be assigned to 3 virtual keys, each virtual key is assigned to 9 characters.
Consider user's use habit, here the character on virtual key is arranged still according to the layout of Qwerty keyboard, Fig. 4～Fig. 6 has provided three kinds of concrete layouts, in each layout, all touching 3 virtual keys of screen display, each virtual key is exactly an input area, and the character that each input area is assigned to can show domination on touch-screen, can certainly recessively process, do not show any character, only show corresponding input area.These 3 virtual keys are called after S key, G key and K key respectively.In Fig. 4, be wherein that 26 letters add an enter key character (enter key character is distributed in the lower right corner of K key), in Fig. 5, be that 26 letters add that (" Space " in Fig. 5 represents space bar to a space bar character, be distributed in the lower right corner of K key), in Fig. 6, be that 26 letters add a fullstop character (". " in Fig. 6 represents fullstop, is distributed in the lower right corner of K key).Certainly, 27 characters allocation scheme on virtual key can also be different from Fig. 4～6, and change wherein certain or some alphabetical positions is all fine.
Because virtual key quantity significantly reduces, therefore each virtual key can take larger area, and larger interval also can be set between virtual key.As shown in Figure 4, the character difference that the gesture of the different glide directions on each virtual key is corresponding, for example:
The gesture that starting point is slided on S key, to the upper left corner is corresponding to alphabetical Q;
Starting point on S key, to directly over slide gesture corresponding to letter w;
The gesture that starting point is slided on S key, to the upper right corner is corresponding to letter e;
The gesture that starting point is slided on S key, to front-left is corresponding to alphabetical D;
The gesture that starting point is slided on S key, to the lower right corner is corresponding to letter C;
Starting point on S key, under slide gesture corresponding to alphabetical X;
Starting point on S key, left inferior horn slide gesture corresponding to zed;
The gesture that starting point is slided on S key, to front-left is corresponding to alphabetical A;
Starting point, on S key, but does not have the gesture of glide direction corresponding to alphabetical S.
Can find out, the gesture that alphabetical S is corresponding is there is no glide direction (be that user only clicks S key, do not slide on S key), and other alphabetical corresponding gesture on S key all has glide direction.For example, user, in the time of needs input alphabet W, only need to input a gesture, and the starting point position of this gesture should be on S key, and the glide direction of this gesture be to directly over slide.Equipment Inspection, after this gesture, is searched the character corresponding with this gesture in the corresponding relation of setting up in advance, finally can identify this gesture corresponding with letter w, therefore to upper layer application input alphabet W.Gesture on S key is more than described, for the gesture of inputting on G, K key, has also had similar corresponding relation, repeated no longer one by one.
Input mechanism in the present embodiment can be determined by fuzzy logic starting point and the glide direction of gesture, to improve the tolerance of input.For example, in the operation of above-mentioned input alphabet W, the starting point of the gesture of user input can be at the central point of S key, also can be on S key on other position of non-central point.As long as clicking, just input S, even if this click occurs in the region that indicates Z on S key on S key.And, the glide direction directly over described can be vertical 90 degree upwards, can be also the direction that left and right is departed from 90 degree a little.As shown in Figure 4, owing to there being 8 glide directions on S key, therefore the deviation range that each glide direction allows is 360/8=45 degree, and glide direction is moved the gesture in 22.5 degree in the upper left right avertence of vertical 90 degree upward direction, the present embodiment all by be judged as to directly over the gesture of sliding.As long as the upward sliding in this scope, just input W, even if being the region that indicates C from S key, this slip slides to the region that indicates D.For the gesture of just spending in left and right skew 22.5, can provide corresponding two characters to select for user, for example, when be offset the gesture of 22.5 degree left in vertical 90 degree upward directions, provide alphabetical Q and W to supply user to select.Fuzzy Processing for other glide direction is similar therewith, repeats no more.
Below describe as an example of corresponding 5 characters of each virtual key example again.Fig. 7 shows a kind of part virtual key of dummy keyboard, and each virtual key, corresponding to 5 characters, if need to input so above-mentioned 27 characters, at least needs 6 virtual keys, has only provided wherein 3 buttons in Fig. 7.As shown in Figure 7, can input and comprise that the gesture of four kinds of different glide directions and one do not have the gesture of glide direction on each virtual key, these gestures correspond respectively to 5 characters.For example,, on the T key in Fig. 7: to directly over the gesture of sliding corresponding to alphabetical Q, under the gesture of the sliding gesture of sliding corresponding to alphabetical D, to the front-left gesture of sliding corresponding to alphabetical A and front-right there is no the corresponding alphabetical S of gesture of glide direction corresponding to alphabetical D.Move the gesture in 45 degree for glide direction in vertical 90 degree upward direction upper left right avertence, the present embodiment all by be judged as to directly over the gesture of sliding.
The present embodiment can also be inputted arabic numeral by dummy keyboard, and principle is identical with input alphabet.As shown in Figure 8, can utilize a digital dummy keyboard corresponding to 9 arabic numeral, so only need a button, just can input 1～9 these 9 arabic numeral.
Can find out from the above, in the embodiment of the present invention because a virtual key can be corresponding to multiple characters, therefore the number of keys on dummy keyboard can significantly reduce, for example the present embodiment can only just can be realized the input of all English alphabets with 3 virtual keys, thereby button area and button interval are increased on limited screen, owing to increasing button area and interval, the present embodiment can obviously reduce the requirement to input precision of gestures, and solve because input pen or finger block virtual key and affect the problem of input, thereby improve the availability of dummy keyboard, facilitate user's input operation, reduce the generation of the situation of input maloperation, make input fast and touch system become possibility.And less virtual key can take less screen/fuselage area, can reserve more area and offer equipment and show.
