Problems solved by technology

This method has a high recognition rate, but because it involves a large number of pattern recognition-related algorithms and the recognition process is complicated, the recognition response is relatively slow, and it is usually used for handwritten character recognition
For the recognition of mouse cursor movements, due to the rough movements, the accuracy of trajectory recognition is not high, but the recognition speed is high, so the method of dot matrix recognition is not suitable.

Embodiment

[0023] Such as figure 1 As shown, the recognition process of the mouse gesture recognition method of the present invention comprises the following steps:

[0024] (1) Establish a virtual coordinate system in 8 directions on the screen with the current mouse cursor point as the origin, such as figure 2 As shown, and number each coordinate direction axis to form a mapping relationship between each coordinate direction axis and the number. Each coordinate direction axis is clockwise as upper right 1, right 2, lower right 3, lower 4, lower left 5, left 6. Upper left 7 and upper 8;

[0025] (2) The message processing module records the coordinate value of the current mouse cursor point, which is recorded as the starting point coordinate; after the mouse moves, the message processing module records the coordinate value of the mouse cursor point, which is recorded as the end point coordinate, and sends the starting point coordinate and the end point coordinate to the gesture compu...

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 [0001] The invention relates to the field of computers, in particular to a mouse gesture recognition method. Background technique [0002] At present, as a new type of interactive display device, the touch screen is more and more widely used. Large-area touch screens are widely used in electronic sand tables and conference discussions. Therefore, when developing application software for touch screen devices, it is necessary to consider how to make users It is faster and easier to operate the software with a touch screen, and at the same time, it provides a simple interface to develop this shortcut for secondary development programmers. [0003] By recognizing the mouse cursor action, the specific action of the user on the touch screen can be converted into a program message, so that the programmer of the secondary development can make corresponding processing according to the program message. For example, when the user draws a circle on the touch screen, the...
