Problems solved by technology

[0003] At present, there are two problems in the multi-touch technology. First, the calculation data of multiple touch point coordinates is large, and the touch device is limited by the hardware. Generally, the touch device itself cannot directly calculate the touch point coordinates, and a computer system is required to assist in the processing. ;Secondly, the computer system calculates the coordinates of the touch points and then sends the coordinates of the touch points of multi-touch to perform corresponding operations. It needs to write the corresponding driver, the development cycle is long, and the effect is not good and unstable

Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 As shown, it is a schematic structural diagram of a multi-touch system data processing device in the present invention. The multi-point touch system data processing device includes a control device, a USB interface module and a touch device. The control device is a computer, the touch device is an infrared touch device, and the touch data is an analog-to-digital conversion value of an infrared receiving tube in the infrared touch device. The control device recognizes the touch device as a USB mass storage device and receives the touch data sent by the touch device through the USB interface module to calculate the coordinates of the touch point and send the coordinates of the touch point to the touch device. The control device also reads the man-machine interface of the touch device The device descripto...

Abstract

The invention relates to the field of touch system data processing, in particular to a multipoint touch system data processing method and a multipoint touch system data processing device. The multipoint touch system data processing method comprises the following steps that (1) a touch device sends touch data to a control device; (2) the control device receives the touch data; (3) the control device works out a touch point coordinate according to the touch data and sends the touch point coordinate to the touch device; and (4) the touch device sends the touch point coordinate to the control device in a mode of universal serial bus (USB) man-machine interface equipment, and the control device execute corresponding touch operation according to the touch point coordinate. The multipoint touch system data processing method and the multipoint touch system data processing device can effectively improve effectiveness and stability of multipoint touch and shorten system development period simultaneously.

Description

technical field [0001] The invention relates to the field of data processing of a touch system, in particular to a data processing method and device in a multi-point touch system. Background technique [0002] Touch screen technology and corresponding digital interactive equipment have greatly improved the interaction between people, brought great convenience to people, enriched people's lives, and are widely used in video conferencing, teaching and other fields, and are becoming more and more popular A platform and medium for people to communicate in real life. [0003] At present, there are two problems in the multi-touch technology. First, the calculation data of multiple touch point coordinates is large, and the touch device is limited by the hardware. Generally, the touch device itself cannot directly calculate the touch point coordinates, and a computer system is required to assist in the processing. ; Second, the computer system calculates the touch point coordinates...
