A method and system for processing touch data of an infrared touch screen based on a 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.

Description

technical field [0001] The invention relates to an infrared touch interaction technology, in particular to a touch data processing method of an infrared touch screen based on a pressure-sensitive pen. Background technique [0002] Infrared touch screen (Infrared Touch Screen Technology) is a display device that uses the dense infrared matrix in the X and Y directions to detect and locate the user's touch. It is composed of infrared emitting and receiving sensing elements installed on the outer frame of the touch screen. An infrared detection network is formed on the top. Any touching object can change the infrared rays on the contacts to realize the touch screen operation. When the user touches the display screen, the finger will block the two infrared rays passing through the position, so the position of the touch point on the display screen can be judged, and then converted into the coordinate position of the touch to realize the response of the operation. [0003] In an...

Problems solved by technology

However, most operating systems do not support pressure-sensitive operations, resulting in the inability to realize diversified control of view controls. It is necessary to add a pressure-sensitive control method for view controls. For example: during the operation of infrared touch, due to infrared Due to the height limit of the touch frame, the user triggers the positioning operation when the user does not actually touch the screen, especially during the writing process, it is easy to cause misoperation. In addition, the existing view controls cannot realize different functions according to the intensity of pressure sensitivity.
