Background technology
U.S. Patent application No.2004101172(Lane)Disclose a kind of finger imaging system of finger for recipient
System, its fingerprint is obtained using automatic fingerprint reader.The system includes the finger for having for receiving the finger for being acquired fingerprint
The finger imaging device of receiving portion.Locating rod stretches out from finger receiving surface, in finger is approximately in ideal position
When, it engages the wrinkle of skin of subject finger.U.S. Patent application 2004101171(Lane etc.)Disclose a kind of for receiving
With the finger imaging system of the finger for keeping people, its fingerprint is obtained using automatic fingerprint reader.The system includes thering is finger
The finger imaging device of receiving portion and finger position portion, the part forms the recess for reducing size so as to be forced together
The subject finger being inserted to property is maintained in settling position.And last, U.S. Patent application No.2004076314
(Cheng)A kind of equipment is disclosed, it includes fingerprint sensor and guide.The sensing position of fingerprint sensor fills with guiding
The guide plane put forms relative and obtuse-angulate angle.
Traditionally, in order to record fingerprint, by ink be coated to finger and then finger by " rollings " pass through paper or
Other ink receptive surfaces are printing fingerprint image.By contact surface and the fingerprint that leaves Residual oil and leave by various technologies
Catch, their " lifting " and disclose fingerprint.
In recent years, alternative technology is proposed, they can disclose the tiny characteristics in fingerprint and directly from finger
Or fingerprint is caught with the biological tissue below the finger skin surface for forming finger minutiae to outgrowth.Electronic transducer technology
Including when system by finger areas or only finger areas a part detection skin or histological difference so as to disclose fingerprint
Image is illustrated to form the electronics of fingerprint, such as when as digital document, finger is kept on sensor-based system.The example
Including optical scanner, electro-luminescent pressure sensor-based system, the integrated circuit of the electric capacity that can measure each pixel size etc..
The production cost of some type of fingerprint scanning systems is subject to promoting by the size in sensing finger region.For silicon
Base or integrated circuit(IC)Type sensor is particularly so.Such as most of IC, IC is bigger, if device geometry and the number of plies
Equal, then its production cost is higher.The production cost of sensor is directly relevant with sensing area, and sensor is extensive
Production, when the relevant part of only finger needs to be scanned to set up fingerprint identification system, thumbnail size is not optimal.Such as
Fruit using only the relevant part of fingerprint to reduce system cost, then importantly, for every time differentiate or identification events, will with
The relevant part of the finger of first registers is almost identical to be partially disposed on sensor.
Obvious less sensor cost is lower, and assume by the relevant region of sensing finger be still necessary to it is sufficiently large with
Acceptable matching capacity or safe class are provided, then preferred plan will be this less sensor, not consider most
Whole finger-print region.Finger guide device of the invention is such a device, and it can be used for reliably on small sensor
Finger is repositioned to carry out identification effectively.The device reduces due to finger not being positioned to be sufficiently close together
False Rejects caused by one or more positions of its initial registration.The finger guide device ensures that sensor can read and refers to
The relevant part of line matching, it is used to ensure to read those for catching and storing with for the template for comparing and matching substantially
The relevant part of identical.When every time using fingerprint recognition system, the finger guide device is by naturally(For example, cosily
Or intuitively)Non-mandatorily subject finger is directed to substantially(Substantially)Reduced at identical and initial registered location
The generation of False Rejects.
When smaller sensors are used, if registering finger in such a manner, that is, a relevant part of finger is scanned,
Or may finger printing area multiple laps, then they be electronically assembled into by computer and represent initial subject and refer to
One complete " template " of the bigger part in part that any independent scanning of ratio of line can be produced alone, then the system rely on
In subject user can as one man feeler be passed so as to the relevant part of matching of finger in identical approximate location
Sensor reads and thus allows for accurate discriminating.Not reapposing finger accurately in essentially identical position causes mistake
Refusal;, or in other words, because sensor sees the different and irrelevant region of finger, then it can not be from a template
The relevant fingerprint portion matched data in preceding registration, and it refuse it is known can received subject user.This is a kind of
False Rejects.If system its other trial, and if second or subsequent trial final alignment contain matching and exist
The details of the fingerprint about part of part is initially stored during registration, then the main body is received(Identified or " discriminating ").Pass through
There is provided simple for one kind of finger, basic oval or rectangular in shape funnel-form guiding piece, the guiding piece actually promotes finger to enter
In entering correct position, and for subject user provides various haptic feedback devices so that it " finds " just more easily again
True position, even if passing by between registration and next discriminating event for a long time, the finger guide device is reduced and is used for
Differentiate the average time of the trial of known main body.Conversely, being enclosed using basic flat surface sensors or by substantially flat surface
Around sensor or the even sensor of poor design, for the main body not being trained to, the model of this false rejection rate
Enclose 10 to ten five from all trials, or the even more high for different system setting.
The content of the invention
Substantially round, avette, square or rectangular funnel guiding fluid is very similar to enter in container;Finger guiding dress
Put or finger " pit "(Recess)For guiding finger towards same position on a sensor in a repeatable fashion.Another letter
Single analogy is to describe the ball in cone apex, with the ball phase being seated at the global minimum of reverse taper or recess
Than it is unstable, and wherein ball is rolled to identical global minimum position always by Action of Gravity Field and recess sidewalls.
In the situation of finger guide device, so not obvious effect is started by muscle, so as to apply appropriate active force to hold
Change places and slide finger towards sensor region, by the communication with subject user and the proper motion towards the position, this
Plant and move described in finger guide device and disclosed physics, material and tactile element guiding with each time by hand
Finger is directed to touch feedback reality from the side wall that in ergonomics mode designs of the same position also by the device
The existing proper motion.The sensor will be seated in finger guiding in neighbouring correct position of the preferable finger about region
So as to the preferred part of " seeing " fingerprint in window at bottom of device(It is raised).
Focus on keeping on finger to carry out the former device of fingerprint imaging for positioning finger(Almost extrude)To flat
Requirement on scanning of a surface and the skin wrinkle below the first joint for tending to roughly from nail leading edge or in finger
Line positions finger.This intention seems to substitute the effect of rolling fingerprint and seems to turn into a weight for flattening the pressure of finger
Want element.Modern semiconductors or sensor require nothing more than contact gently, and as observed by, often focus on constantly repeating to sweep
The essentially identical relevant position of fingerprint is retouched or catches, as long as finger keeps substantially active alignment sensor.The present invention is provided
A kind of effective auxiliary and a kind of learning organization, it contributes to main body that finger is positioned at into correct position on the basis of repeatable
In putting, and finger relevant part alignment scanner or sensor, and also by including physical form, feedback device and material
One group of approach of characteristic forms correct contact(Pressure).Additionally, the device is designed to non-mandatorily reposition fingerprint region
Domain, the distance on the downside of the region to nail substantially between 0.20 and 0.90 inch, and therefore, from the finger from below nail
Convex ridge below point positioning rather than the first joint in finger.Additionally, the finger guide device ridge tool at front portion
There is sufficiently low profile to avoid contact with nail.This contact is introduced into error, because different subjects are sometimes in the different time
It is different length by its Nail clipper, and it is most of it will also be appreciated that the pressure acted in nail tip is uncomfortable, and this two
The situation of kind is present in former device to position finger on fingerprint reader or scanner.
The physical Design of finger guide device makes it possible to precisely enough by finger about being partially disposed in sensor
To significantly improve receiving for the first time on center(It is registered main body)Percentage.This is included at finger guide device front portion
The short concave radius of comparing(Or the slope of steeper), herein, finger tip contacts or close just below nail
The front portion of finger guide device;And the radius concave shape more long of proximity sensor opposite side(Or without so precipitous
Slope), herein, cup extends towards human body along finger.Side on the either side of scanner or sensor region is very
In determining on scanner or sensor the precipitous relevant parts transversely to keep finger.Generally, the finger guide device
Size is suitable to general finger, but is adapted to wide range of finger size because it only contact finger or refer to it is less
Relevant part.
What is allowed for finger is placed on installation less electronic sensor on flat surfaces allows
Degree is quite tolerant, however positioned on these devices without the finger guide device benefit the relevant part of finger for without
It is difficult for the main body of training.This may be limited to the substantially half of finger-print region that will be scanned to three/it is double
About part, this depends on algorithm and system accuracies used to other of scanning and the fingerprint that is present in template before being stacked in.
Low accuracy systems can be operated so that being set lower than the sensor window of half in differential scanning and its in by storage template
Crossover between corresponding relevant part.Actual relevant for secure match requirement partly depends on algorithm, and in algorithm
In, actually required safe class or security setting.This and the scanned main body that template is associated that is registered with the main body
Fingerprint relevant part it is related.
It is consistent with it is repeatable on the basis of by the identical of fingerprint about being partially installed in the effective coverage of sensor
(Window)On ability be easy to quickly and precisely first attempt matching and this significantly reduces false rejection rate.It is being registered
But unskilled main body in, False Rejects are reduced to 10 by the finger guide device invention.Drawn using the finger
The practice for leading device or system optimization or combination of the two will further decrease false rejection rate;And using optimised
In the ideal case of system, false rejection rate can be fallen below percent by the finger guide device in contact pilotage or pen
Two.
Refused from the mistake in the range of 10% and 20% for attempting and with about 15% to the average value less than 2%
The reduction of exhausted rate is significant in terms of the security system based on pen or contact pilotage receives with market acceptance.Subject user
Sense of frustration in crowd is significantly reduced, if people without multiple-contact sensor so as to being received.This is in pen or contact pilotage
It is especially important in, wherein generally needing specific user's dexterity to be carried with for discriminating trial other each time
Play and change finger.As aiding in and being easy to this device practical operation being required to the special dexterity demands of reduction,
Some pens for being equipped with fingerprint include special pliable clamping or non slip grip surfaces.
At year ends 2003, a kind of new keyboard is introduced to substantially 250,000 user and without finger guiding
Device scheme.The company that there is sizable setback in user library and dispose the system faces severe criticism.This problem
So that user queries the service behaviour of system, even if the problem is considered as technically user's no essence in discrimination process
True placement finger(Misalignment sensor)Mistake or user error.Finger guide device reduces this expected user
Mistake and improve first time contact in the received possibility of main body.This has saved the plenty of time on lifetime of system
And be the key element for developing biometry system, in terms of user time and efficiency it can as one man with password or
PIN is compared.
In practical operation and application, registered using finger guide device and discriminating is improve finger guide device
Effect.Because the natural feeling of finger guide device directed the user to each time in ergonomics mode it is roughly the same
Position or the relevant part of finger is aligned on effective sensitive zones.This bootup process is physics and neutral,
Used hence for first time and provide touch feedback with for subsequent study.
During registering, system may in multiple times require main body movement finger and make finger contact scanning device or sensor
(For example, " lifting and replacing " finger).Finger guide device is generally designed to accommodate the hand of left side or right side limbs
Refer to or thumb.This shows that it contributes to this multiple placement but this placement strictly is not limited into accurate and essence
The accurate placement for really repeating, it only causes this being placed in the permissible range of sensor and algorithm so as to subject finger
Relevant part alignment scanner or sensor.This allows template to exceed preferable or " suitable " window frame(It is raised)Strict limit
Make and therefore form buffer zone, it is designed in the range of permission adapt in following appropriate misalignment grade
And the guidance capability of finger guide device.For long-term, for repeatable energy, this function is important, and by
The alignment ability that finger guide device promotes only needs to be increased to the limit required by matching system, including but not limited to template size
With the safe class of algorithm.
Some sensors drive current potential or electromagnetic signal to enter in finger tissue.This can be radio frequency signals.Hand
Finger guide or its surface can be conductive so as to be easy to this application during registration and subsequent discriminating event.Finger
Guide may be designed to have the preferred embodiment of basic parabolic shape will reflect with during being referred to as illuminating
Electromagnetic energy is focused on the relevant part of finger and improved by the feature of heat transfer agent.
The surface characteristic and material for being selected for finger guide device are important for performance.Because finger should
This is easy to slide in place, low-friction coefficient(Slide coefficient and static coefficient)For allowing finger to be still in its natural overall situation most
It is useful at small value position, the position is located at the bottom of the finger guide device of appropriate positioning on scanner or sensor
At portion.Constantly be positioned at finger in identical close position by the surface characteristic and outcome procedure.With appropriate low friction system
Several example of material include but is not limited to smooth metal, smooth plastics are even painted, polishing or waxing surface.Such as
Fruit surfacing has coefficient of friction high, such as rubber, polyurethane-based material or rough plastic, the effectiveness of finger guide device
Can be lowered or damage with function.Moistening or dry lubricant and cured it also is coated with and appropriate lubricant or even can quilt
It is mixed into clean solution or special cloths for cleaning.
Other feedback devices can be included in of the invention preferred or even alternative embodiment.When they are used
Finger guide device through lasting, people are by the ability of sensigenous to correct position.The finger guide device can be by having
The material of pyroconductivity high is made to provide touch feedback and accelerate this learning process.Example includes but is not limited to gold
Category, some ceramics or some carbon-based materials.In this case, finger guide device will make us in the contact of room temperature
Feel colder(Relative to pen or the other parts of contact pilotage), this is not due to its absolute temperature, and because it has works as
When being touched, the pyroconductivity that heat is quickly gone out from skin conductance, therefore the quick sensitive table for cooling down finger in contact
Face.If finger guide device is made of metal, the characteristic will make it feel like metal contact(Such as cold sensation).Pass through
Compared with silicon sensor and its face coat, feel colder than the remainder of pen, main body is by cognitive finger guide device
Correctly " feel " and also will preferably sensory transducers.
Other protuberance can be added to help orientation finger or cause main body " accurate adjustment " their finger position.These
It is probably unnecessary for normal or average-size finger, but the main body has the hand of contact very little wherein
It is valuable in the application of the very small finger that apparatus surface region is led in guide.
Braille dots can be added to finger guide device in order to blind person or user visually impaired.
The finger guide device also can be used physical component and material property to prevent inaccurate use.For example, implementing
A preferred method of the present invention is using harder and unique convex ridge around the finger guide device.Not it is perceived by danger
" sharp " object of danger, this convex ridge is used to enable that subject user does not feel well.When a finger is placed across this ridge,
Although harmless, it is uncomfortable, because it applies pressure per square inch high on narrower convex ridge line to skin
(PSI).This pressure per square inch high shows that pen is not held correctly in sensing contact.The sense of non-aligned clamping
Feel is unnatural sensation and user will by the light of nature to reposition his or her grasping more naturally and comfortable to obtain
Sensation.Naturally tendency is to avoid clamping pen in the outer ridge of finger guide in one's hands, but by finger or thumb
Slide down in finger guide device and slide into sensor(Desired position)On.Exactly in the correct position, for
For subject user, keep contact pilotage feels it is natural and safe(Stabilization).Sometimes be used interchangeably and conduct
The contact pilotage of the equivalent form of value or the wording of pen, herein, for including any elongated instrument, it to be kept or clamped simultaneously by user
And can write on the surface.
Further embodiment of the present invention may include active feedback mechanisms, including be designed to for being properly positioned its finger
Remind(And training)Main body or be designed to remind main body they received in systems(I.e. their fingerprint is swept
Retouch, contrast and correctly match)The fact feedback.Sound can be used for " guiding " finger and reach sensor.Also can be used visual
Indicator.Finally, physical motion for example vibrates can remind driver's stall warning to be very similar to when driving an airplane
The mode of rod type electromagnetic shaker and used.In another preferred embodiment of finger guide device, with feedback " ticktack "
Pressure-responsive motion is used as tactile(And the sound)Feedback signal is with when finger is in guiding piece and applies connecing for proper range
User is informed during touch pressure.
The mistake that these feedback mechanisms may be alternatively used for correction system is used.For example, limiting pressure on a sensor or
Person lacks contact and can cause scanning problem.Sometimes subject user may feel disappointed because of false rejection rate, may not be just
Really show that finger pressure higher will cause the conclusion of system more good berth.Excess pressure can flatten details and cause to pass
Sensor saturation and prevent it from accurately resolve minutiae.May be such that details not conversely, form is the kick the beam absence of pressure of contact
Can be differentiated by sensor and good image can not be produced.In any case, voice command or sound or art technology
Other feedback devices known to personnel can be used for transmitting needs the requirement to loosen clamping or even more strongly extrude.Language
Sound or sound or other feedback devices can be passed on to main body and need to mitigate contact or somewhat lift finger.It is another feasible
