Embodiment 1

[0040] figure 1 The implementation process of the gesture recognition method provided by the first embodiment of the present invention is shown, which is detailed as follows:

[0041] In step S101, the gesture operation signal data is collected according to the gesture operation on the touch screen.

[0042] This embodiment can be used for touch screens for gesture operations, including resistive touch screens, capacitive touch screens, acoustic wave touch screens, infrared touch screens, etc. When the user performs a gesture operation on the touch screen, the touch screen terminal will collect gesture operation signal data.

[0043] In step S102, the gesture operation signal data is analyzed and processed through a pre-stored gesture recognition algorithm to obtain coordinate data of each touch point and gesture operation data.

[0044] Preferably, the gesture operation includes: single-finger click, double-click and long press, two-finger movement, distance, approach and rotation, t...

Embodiment 2

[0059] In order to further explain the step of analyzing and processing the gesture operation signal data through the pre-stored gesture recognition algorithm in the first embodiment, obtaining the coordinate data of each touch point and the gesture operation data, so as to perform gesture operations on the infrared touch screen. The terminal adopts a gesture recognition algorithm to perform gesture recognition as an example; the infrared touch screen includes an infrared unit; the touch screen terminal includes a USB interface and a micro control unit (Micro Control Unit, MCU).

[0060] figure 2 Shows the flow chart of gesture operation based on infrared touch screen, touch screen terminal adopts gesture recognition algorithm to perform gesture recognition, detailed as follows:

[0061] In step S201, the device is initialized. The infrared touch screen and the touch screen terminal are initialized.

[0062] In step S202, the MCU controls the infrared tube matrix to collect initial...

Abstract

The invention is applicable to the field of touch screen terminals and provides gesture recognition method and device and a touch screen terminal. The method includes the steps: acquiring gesture signal data according to gestures on a touch screen; analyzing the gesture signal data by pre-stored gesture recognition algorithm, and acquiring coordinate data and gesture data of all touch points; recognizing a connected operating system; and converting the coordinate data and gesture data of all the touch points into coordinate data and gesture data of the touch points, recognizable to the operating system. Gesture recognition for at least one finger is realized, and gesture recognition results are processed into the corresponding formats according to the connected different operating systems. The recognition of multiple gestures is achieved by the gesture recognition algorithm, and compatibility of various operating systems is also realized.

Description

Technical field [0001] The invention belongs to the field of touch screen terminals, and in particular relates to a method and device for gesture recognition and a touch screen terminal. Background technique [0002] At this stage, more mature touch screen technologies include: resistive touch screen, capacitive touch screen, acoustic wave touch screen and infrared touch screen. However, the existing touch screen terminal simply outputs the coordinates of the touch point without integrating advanced gesture recognition algorithms, and cannot be operated quickly through more gesture operations. [0003] In addition, windows7 in the windows operating system series supports multi-touch, but lower versions such as windows xp do not; some versions of the Linux operating system series, MAC OS operating system series and Andorid operating system series do not support touch screen technology. However, the existing touch screen technology is mainly developed for a single operating system, ...
