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. The touch device itself generally cannot directly calculate the touch point coordinates, which requires the assistance of a computer system. ; Second, after the computer calculates the touch coordinates, it needs to write the corresponding driver to send the multi-touch touch point coordinates to the computer system. The development cycle is long, and the effect is not good and unstable. , can not achieve plug and play

Abstract

The invention discloses a multi-point touch data processing method and a multi-point touch data processing system thereof. The multi-point touch data processing method comprises a computer and a touch device with a driver type supporting Autorun function, and an interface module is arranged in the touch device, and a coordinate point calculating program is solidified in the touch device. The method comprises the following steps that the touch device is connected with the computer through the interface module; the computer configures a driving program for the touch device, and identifies the driver type supporting Autorun function of the touch device; the computer runs the coordinate point calculating program solidified in the touch device and appointed by an Autorun.inf file; the computer detects and acquires touch data from the touch device, and executes the coordinate point calculating program to calculate a touch point coordinate; the computer sends the touch point coordinate back to the touch device; and the touch device transmits the touch point coordinate to the computer in a mode of USBHID (universal serial bus human interface device) equipment, and the computer executes the corresponding operation. The touch device can be directly connected and communicated with the computer without mounting any software for the computer, and can calculate the touch point coordinate, realize touch function and really realize free driving.

Description

technical field [0001] The invention relates to touch technology, in particular to a multi-touch data processing method and system thereof. Background technique [0002] The emergence of touch technology has brought great convenience to people, especially the application of multi-touch technology has brought a qualitative leap to the touch experience and greatly improved the interaction between people.
