Abstract
The invention provides a mouse gesture identification method. A starting point coordinate and an end point coordinate before and after the movement of a mouse cursor point are recorded by a message processing module by establishing a multidirectional coordinate system and then calculated in a gesture computing module to judge the moving direction of the mouse cursor point; after the circulation of the steps, the direction value sequence obtained is sent to a sequence analysis module; and the group that is best matched is found in a feature sequence database by comparison and the corresponding action information is output. The method of the invention has fast computing speed and high identification efficiency, thus being convenient for the operation of a touch screen user on software greatly; meanwhile, a control manufactured by adopting the method is greatly convenient for the programmers for secondary development to develop the touch screen application program.
Description
Technical field
The present invention relates to computer realm, particularly a kind of method for recognizing mouse gesticulation.
Background technology
At present, touch-screen is as a kind of novel mutual display device, its range of application more and more widely, the large tracts of land touch-screen is widely applied in goods electronic sand map and panel discussion, so when being touch panel device Application and Development software, just must consideration how to make the user more fast and simple with touch screen operation software the time, the simple and easy interface of this shortcut of exploitation is provided for the programmer of secondary development simultaneously.
By the action of identification cursor of mouse, can be converted into program message to the specific action of user on touch-screen, allow the programmer of secondary development make corresponding processing according to program message.For example, when the user draws a circle on touch-screen, then drawing a circle this message parse and send to the programmer of secondary development, the software function that the programmer only need design this corresponding execution of action institute of drawing a circle gets final product.Being equivalent to is not having to provide a cover " shortcut " for touch screen user under the situation of keyboard.
Discern the cursor of mouse action, can adopt the dot matrix identification mode usually.Specifically, the track that cursor of mouse is moved is noted with latticed form exactly, by comparing one by one with existing movement locus dot matrix, therefrom draw the highest movement locus dot matrix of similarity, the track that this cursor of mouse is moved resolves to the pairing specific action of movement locus dot matrix of coupling again.This mode discrimination is higher, but owing to relate to a large amount of pattern-recognition related algorithms, the identifying complexity so recognition reaction is comparatively blunt, is generally used for handwriting identification.And for identification cursor of mouse action, not high because action is rough, and recognition speed is had relatively high expectations to the track identification accuracy requirement, so dot matrix identification mode and being not suitable for.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of fast operation, method for recognizing mouse gesticulation that recognition efficiency is high are provided, this method greatly facilitates the operation of touch screen user to software, and the control of making by this method programmer that greatly facilitates secondary development carries out the exploitation of touch-sensitive screen application simultaneously.
The present invention is achieved through the following technical solutions: a kind of method for recognizing mouse gesticulation may further comprise the steps:
(1) on screen, is that initial point is set up a virtual multi-direction coordinate system, and is each coordinate direction axle numbering, form mapping relations between making each coordinate direction axle and numbering with current cursor of mouse point;
(2) message processing module writes down the coordinate figure of current cursor of mouse point, is designated as starting point coordinate; After mouse moved, the coordinate figure of message processing module record cursor of mouse point was designated as terminal point coordinate, and starting point coordinate and terminal point coordinate is sent to the gesture computing module;
(3) in the gesture computing module, preestablish the error angular range of each coordinate direction axle, and the minor increment between terminal point coordinate and the starting point coordinate;
(4) the gesture computing module calculates the distance between terminal point coordinate and the starting point coordinate, if it is worth the setting value less than minor increment, then terminal point coordinate is invalid, and identification stops; If its value is not less than the setting value of minor increment, then terminal point coordinate is effective, the judgement of approach axis;
(5) connection source coordinate and terminal point coordinate calculate the differential seat angle between the immediate coordinate direction axle of its line and direction, if its value exceeds the error angular range of setting, then terminal point coordinate is invalid, and identification stops; If its value is in the error angular range of setting, then terminal point coordinate is effective, and the direction value that draws is stored in the sequential analysis module;
(6) repeat above step, several direction values that obtain are stored in form a prescription in the sequential analysis module to value sequence;
(7) sequential analysis module is analyzed the direction value sequence, predefined standard value in all directions value and the characteristic sequence storehouse is compared, find out immediate standard value and replace the direction value, determine at last in the characteristic sequence storehouse, to mate most one group with the direction value sequence, the action message that output is corresponding.
The described multi-direction coordinate system of step (1) is preferably the plane coordinate system of 8 directions, each coordinate direction axle be in the direction of the clock upper right, right, bottom right, down, lower-left, a left side, upper left and on; Each coordinate direction axle is equipped with the error angular range, is provided with the minor increment between terminal point coordinate and the starting point coordinate simultaneously.
Described error angular range is 20～40 °, and promptly each coordinate direction axle both sides respectively are 10～20 °; Described minor increment is 5～15 pixels.
The described characteristic sequence of step (7) storehouse is the characteristic sequence storehouse of freely expanding, and its content can be provided by the primary development programmer, also can freely add expansion by the programmer of user or secondary development.
The content in described characteristic sequence storehouse is specific cursor track, also can be the computing formula of specific cursor track.
Compared with prior art, the present invention has following beneficial effect: method for recognizing mouse gesticulation of the present invention, and the recognition speed height carries out sequence alignment than dot matrix identification weak point operation time, favorable expandability, the programmer of secondary development can create self-defining gesture as required and discern; Simultaneously, this method greatly facilitates the operation of touch screen user to software; Generally speaking, the secondary development programmer can be indifferent to mouse gestures identification work and only need carry out the software function exploitation, allows the user freely define mouse gestures and pairing program function thereof by operating habit.
