Title: TOUCH DATA PROCESSING METHOD AND SYSTEM FOR INFRARED TOUCH SCREEN BASED ON PRESSURE-SENSITIVE PEN
Abstract:
A touch data processing method for an infrared touch screen based on a pressure-sensitive pen, comprising: start a pressure-sensitive pen pressure data obtaining service to obtain the pressure data of the pressure-sensitive pen; the pressure-sensitive pen pressure data obtaining service distributes the obtained pressure-sensitive pen pressure data into a system touch event distribution service in an inter-process communication (IPC) mode; a system receives the pressure-sensitive pen pressure data from the system touch event distribution service, and carries out touch data operation processing on an infrared touch screen by combining positioning data of the infrared touch screen. Embodiments of the present invention also provide a touch data processing system for an infrared touch screen based on a pressure-sensitive pen. The embodiments of the present invention utilizes the IPC mode, so that the infrared touch screen can obtain the pressure data of the pressure-sensitive pen, and by combining the positioning data of the infrared touch screen, pressure-sensitive touch operation is realized on an existing infrared touch screen.
