Description
Technical field
The present invention relates to human-computer interaction technique field, more particularly to a kind of automatic matching method and system for inputting information.
Background technology
Current input method automatic error-correcting mechanism, there are two types of types：
1. the input method error correction based on physical button
Such as the laptop using physical button, search dog input method can realize phonetic automatic error-correcting, as phonetic is defeated
When entering " flat " word, " pnig " can be corrected as " ping " automatically.The major premise of this kind of input method error correction is：The button of user is big absolutely
Part is all correct.A small amount of wrong key need to be only directed to carry out error correction or be adjusted for keystroke sequence.
2. the input method error correction based on virtual key
Such as the SwiftKey English input methods on mobile phone, when inputting English " something ", input by mistake for
" domrrhonf ", input method energy automatic error-correcting.The major premise of this kind of error correction is：User wrong key deviate correct key mapping
Apart from very little.If the deviation from more than one key mapping of distance, then error correction effect is poor.
It is the defects of these automatic error-correctings currently：
It can only be used under key position and the smaller scene of correct position deviation；
Keyboard does not have adaptability, while automatic error-correcting, can not optimize the size and posture of keyboard；
It must show keyboard and keyboard is in fixed position.

The word entered.When needing with keyboard (for example inputting password), dummy keyboard is breathed out by breathing out gesture.
Mode two：It is unfamiliar with the crowd of keyboard layout：Keyboard and common input method input mode one are shown using acquiescence
Sample, What You See Is What You Get, difference are to input any position on the screen.
Assuming that the point sequence P={ p of click location1,p2,...,pn, the scheme of the application may comprise steps of.
1. establish dictionary
Signified dictionary of the invention is the dictionary of broad sense, including the phonetic library being made of phonetic, the word of Chinese word composition
Repertorie, the word library of English word composition, the phrase database of English phrase composition, the word library of other Languages word composition, number
The digital library of sequence composition, the maneuver library of action sequence composition etc., what every available sequences represented is collectively termed as " word ", by word
Composition becomes " dictionary ".
It, cannot be as common input method dependent in keyboard layout since self-positioning input method is independent of keyboard
Key position, and be to rely on dictionary match condition prediction user want input word.Dictionary is made of two parts, and one
Part is local dictionary, records the dictionary produced by user, and edited including user or input method inputs automatic raw according to user
Into word.Another part is high in the clouds dictionary, is the main body of dictionary, this has been unziped to from high in the clouds or installation kit before program startup
Ground.
2. Primary Location
If Q is the position of keyboard and the function of state of posture, Q0It is current state, Q ' is the state of previous frame, MRIt is rotation
Matrix, MTIt is translation matrix, MSIt is scaled matrix, it is clear that Q0It is that Q ' is obtained by rotation, Pan and Zoom, then has：
Q0=f (Q ', MR,MT,MS)
It needs to use Primary Location there are three types of situation：
1) when key position sequence input by user is fewer；
2) characters matching returns to undesirable result；
3) other abnormal conditions need default location；
Primary Location is in two kinds of situation：
When | P |=1
Keyboard is without the variation for rotating and scaling, i.e. Q0=f (Q ', E, MT, E), MTIt is then the keyboard centerline by Q ' to coordinateVector determine.
When | P | >=2
Keyboard does not scale variation, only rotation and translation at this time.
MTIt is then the keyboard centerline by Q ' to coordinateVector determine.
MRThen by P={ p1,p2,...,pnAll the points fitting (such as least square method) obtain straight line, by straight line with
Horizontal angle determines that it is more than threshold value more to concentrate or rotate such as point, can not also take rotation amount, this season MR=E.
3. characters matching
By P={ p1,p2,...,pnPoint composition cyclic sequence, then can obtain following characteristics：
The distance of consecutive points：Have after normalized,
The angle of consecutive points has after normalized,
The Hu of point set not bending moment (without loss of generality, by taking third moment as an example)：I3=(y30+3y)2+(3y21-y03)2
It is grouped evaluation function：Refer to that user currently presses the probability of some letter.According to QWERTY keyboard button, each hand
Referring to the letter of control can be grouped, such as left hand little finger of toe control tri- keys of QAZ (probability that little finger of toe presses Q at this time is 1/3), third finger control
Tri- keys of WSX, middle finger control tri- keys of EDC, forefinger control six keys of RFVTGB；Right hand forefinger controls six keys of YHNUJM, middle finger control IK
Two keys, third finger control two keys of OL, little finger of toe control mono- keys of P.
Some equipment, if VR/AR equipment can learn the corresponding triggering finger of each coordinate, thenWherein CiRefer to
Be every group of alphabetical number
Some equipment are then needed according to the corresponding triggering of the characteristic estimatings coordinate such as finger pressure F, contact area S, position P
Finger, then evaluation function：
By above several characteristics, comprehensive score function can define：
S(d,θ,I,f)
Its score S is calculated to each word i in dictionaryi, then SiWith the score S of position sequence0Difference determine its correlation
Property, difference reckling is best match person, i.e.,：
Min Δs S=| Si-S0|
4. calculate keyboard position and posture
After a upper section obtains best match, as shown in Fig. 2, after user's sequence presses four positions (left figure), obtain most
The word of good adaptation is take (right figure).
If P '={ p1′,p′2,...,p′nIt is the coordinate that new keyboard corresponds to button, in order to ask the position of keyboard and posture,
It needs to acquire values below minimum
Since new keyboard is old keyboard through rotating, translating, scaling, if
Due to Sx=Sy=S, therefore compound matrice have totally four unknown parameters, i.e. θ, Tx,Ty, S, then (1-1) available parameter
It is expressed as：
Rational step-length is set, four parameters can obtain by iteration convergence, so as to obtain the position of keyboard and posture.
Referring to Fig. 3, the application also provides a kind of automatic patching system for inputting information, the system comprises：
Click location retrieval unit 100, for obtaining the click location sequence being applied on touch screen, and based on institute
It states the dummy keyboard described in click location sequence pair on touch screen and carries out Primary Location；
Target vocabulary matching unit 200 obtains the corresponding target word of the click location sequence for being matched in dictionary
It converges；
Position and attitude determination unit 300 for being based on the target vocabulary, determines the new of the dummy keyboard after Primary Location
Position and new posture.
Therefore the technical solution that the application provides, have following advantage compared with the prior art：
1) independent of keyboard size and posture；
2) according to the input of user, keyboard can adjust size and posture in real time；
3) good error correction effect can be had by deviateing correct key mapping any distance；
4) keyboard can not be shown.
Technical solution provided by the invention can be applicable to the equipment such as mobile phone, tablet computer, VR/AR, microcomputer, projection
On, when inputting word, do not require to show keyboard layout (can also show) in advance, user needs to be familiar with keyboard layout (if not
It is familiar then need to show keyboard in advance), during user inputs word, keyboard can be according to key position and matching dictionary
Situation carrys out adjust automatically layout.
