In a specific application scenarios, the present invention be based on touch-screen, touch pad, depth camera, VR/AR etc. can The equipment for identifying two dimension (and/or three-dimensional) information of finger tip (and/or both hands), it is keyboard that this equipment, which has an important function, Layout and position can arbitrarily change, no matter whether actual keyboard is shown by display, as long as meeting this Feature can is applied to the present invention.Without loss of generality, it is following to be explained by taking the touch-screen of tablet personal computer as an example.
In use, the finger number K of triggering can be set, K=8 is generally allowed, when finger number is not less than K on flat board When, the display of piecemeal keyboard is triggered, if finger position pattern had occurred, uses the user-defined piecemeal key Disk, otherwise using acquiescence piecemeal keyboard.
1. finger position pattern
When user is put into both hands on tablet personal computer, because everyone custom is different, the position of finger fingertip The relation of putting is a kind of unique feature, and mode position can be described below as the identity code of user in this feature Matching algorithm.
Extract in point set P (finger position collection) a certain essential characteristic (such as distance, area, geometric properties a little Deng), it may make up I × I feature set A=[a1,a2,...,aI], if the change that P passing points put in order obtains Q.Do not lose general Property, using KL characterization methods, build its correlation matrix and using Eigenvalues Decomposition：
Wherein Λc=diag { λaBe sequence diagonal matrix, UcFor corresponding eigenvectors matrix, thenFor P KL Feature set.
Because feature has rotation, order arrangement consistency (such as distance relation, area relationship, specific geometrical relationship), Therefore the acquisition of KL feature sets can be simplified by singular value decomposition：
Due to VAIt is orthogonal matrix, the energy of characteristic vector is by ΛADetermining, descending arranges after A carries out Eigenvalues Decomposition, its Preceding s characteristic value will be much larger than the summation of other all (I-s, and s ＜ ＜ I) characteristic values, i.e., most energy concentrate on s In individual characteristic value,

1) point set P={ p1,p2,...,pI, Q={ q1,q2,...,qI, primitive character collection A, B can be built；
2) according to formula 1-1, P KL feature sets E can be tried to achieve；Q KL feature sets F can similarly be obtained；
3) according to characteristic value E, to F characteristic vector fiSymbol correction is carried out to obtainWherein
4) construction matching matrix
5) whether matched by two-way minimum probability of miscarriage of justice method decision point set P, Q.
2. keyboard piecemeal
Assuming that left hand thumb is respectively to little finger of toe：L={ L1,L2,L3,L4,L5, the right hand is respectively from thumb to little finger of toe：R= {R1,R2,R3,R4,R5, the technology that piecemeal keyboard needs to use is described below.
When the both hands of people are placed on desktop naturally, contacting the fingertip location of desktop has certain pattern, can by upper one section To determine its mode position, its intuitionistic form is as shown in Figure 2, it is seen that when putting down naturally, index finger, middle finger, ring finger and little finger Not point-blank, and can be because of the different gestures of people, mode position has larger difference.Pattern as shown in Figure 3, then It is the pattern when both hands are in larger distance.
If forcing to be adapted to using traditional keyboard, finger can be caused when button, some fingers are average curved in the wrong Can be bigger (such as middle finger) than other fingers, cause easy fatigue.In order to solve this problem, the present invention uses " piecemeal key Disk ", not only allow keyboard to adapt to the hand size of people, be also adapted dynamically keyboard layout so that no longer needed when input Keyboard is found, and two positioning keys of F, J are positioned.Substantially increase the efficiency of input.
Such as Fig. 4.It is the keyboard layout that piecemeal is carried out according to standard key.It is unknown for left hand, the little finger of toe control keys of QAZ tri- Refer to the control keys of WSX tri-, the middle finger control keys of EDC tri-, the forefinger control keys of RFVTGB six.For the right hand, forefinger controls the keys of YHNUJM six, Middle finger controls the keys of IK two, the third finger control keys of OL two, the little finger of toe control keys of P mono-.Grey button is then each piece of host node, same Other keys on block are the child nodes of host node, it is meant that after pattern determines, every finger vertical down by must be by Middle host node, up a key mapping is then by the button above middle host node, by that analogy.Letter and directionkeys etc. are only enumerated herein Piecemeal, other buttons (such as symbolic key) can also carry out piecemeal according to standard finger ring or self-defined fingering.
For there is a certain customers, may some fingers key press habits and standard it is different, can by configuration file or Configuration interface is by User Defined keyboard layout, for example some user B keys are pressed with right hand thumb, and C keys are pressed with left index finger, P Key is pressed with right ring finger, then can define Fig. 5 keyboard piecemeal.
In addition to QWERTY keyboard, numerical key could be used that the form layout of piecemeal keyboard, and Fig. 6 is the numerical key cloth of standard Office.
Fig. 7 is the numerical key piecemeal keyboard after being optimized according to ergonomics, in addition to according to referring to length and bending and stretching optimization, because All it is the right hand generally to press numerical key, the use habit of people can be somewhat toward tilted, its angle of inclination and the separated distance of both hands And arm is relevant with the angle in front.
Fig. 8 is the piecemeal keyboard optimized by ergonomics of directionkeys.
In addition it is also possible to be the piecemeal keyboard of game customization ergonomics optimization, such as existing contemporary games king honor please Refering to Fig. 9 and Figure 10, left hand uses tetra- buttons of Q, W, E, R to use mouse action as technical ability key, the right hand, then definable left hand Keyboard, right handed mouse.The advantage so defined is, as long as user's left hand little finger of toe, which is pressed, just necessarily triggers Q keys (because in this case An only node, and the node is host node), without pipe hand where, be so significantly greatly increased fault-tolerance and Game, user is when playing game, it appears that feels that little finger of toe has a taper knob on hand, never malfunctions.
Same principle, as long as user's right hand forefinger moves, triggering mouse movement；Middle finger clicking trigger left button pulls, nothing Name refers to clicking trigger right button.By that analogy, user can also be according to the hobby of oneself, self-defined shortcut, and game manufacturer can be with The piecemeal keyboard for the ergonomics optimization that acquiescence is set for user according to playing, playability and the operation of game are improved with this Convenience and fault-tolerance.
For different equipment, also can self-defined different operation, for example on flat board, game is generally only applicable right-hand man Thumb manipulation, then can be directed to thumb design interactive mode, as shown in figure 11, left hand thumb control all around four sides To hand thumb controls three different technical ability.
3. scene automatically switches and manual switching
The corresponding relation of configuration file record " scene-piecemeal keyboard " also can be used in the present invention, such as enters certain game picture When, piecemeal keyboard corresponding to triggering, the form of the piecemeal keyboard can be by User Defined, can also be by other users or high in the clouds Server defines.Scene can be started by software to be triggered, gesture triggering, or specific finger position pattern triggering, such as Figure 12.
The application also provides a kind of setting system of button in dummy keyboard, and the system includes：
Keyboard mode matching unit, for detecting the positional information of the finger put on touch-screen, and it is based on institute's rheme Confidence ceases, and judges whether that the keyboard mode that is adapted with the positional information is being locally stored；
Piecemeal keyboard display unit, for according to judged result, displaying to be corresponding to position letter on the touch-screen The dummy keyboard of breath, the dummy keyboard include the piecemeal keyboard corresponding with finger；Wherein, in the piecemeal keyboard at least Including a main button, the main button corresponds to the position that finger vertical touches downwards the touch-screen, with the main button Other buttons on same piecemeal keyboard are arranged to sub- button.
It should be noted that the technical scheme of the application, is not only used on touch-screen, virtual touch face may be also used in (also it can touch and input in three dimensions) on (such as laser keyboard, desktop being invented touch-screen) or somatosensory device.Wherein, The difference of virtual touch face and somatosensory device and touch-screen is：
Touch-screen shows and operated one, and the body-sensing keyboard in virtual touch face and somatosensory device is operation and aobvious Show (for example, operating on the table, being shown on display or projection) of separation.
Therefore in this application, can be according to the positional information of the finger put on touch-screen, to judge whether The keyboard mode being adapted with the positional information be present.If it is present the keyboard mode being locally stored can be called, press According to the general layout of keyboard mode restriction, the position of point fast keyboard in dummy keyboard is set.If it does not exist, then can be according to current The finger put on touch-screen, newly-built keyboard mode.When showing piecemeal keyboard, finger vertical touches downwards the position of touch-screen The position of main button in piecemeal keyboard can be corresponded to by putting, and other buttons on piecemeal keyboard can then be used as sub- button.So, lead to The mechanism that matching mechanisms and piecemeal keyboard are set is crossed, so as to vary with each individual shows dummy keyboard, and biography can be broken The general layout that system keyboard is fixed so that it is more convenient that user inputs information.
