Touch data processing method and touch data processing system for infrared touch screen based on pressure-sensitive pen

Abstract

The invention relates to a touch data processing method for an infrared touch screen based on a pressure-sensitive pen. The touch data processing method comprises the following steps: starting a pressure-sensitive pen pressure data acquisition service, and acquiring pressure data of the pressure-sensitive pen; distributing the acquired pressure-sensitive pen pressure data into a system touch event distribution service by the pressure-sensitive pen pressure data acquisition service by virtue of an inter process communication (IPC) way; and receiving the pressure-sensitive pen pressure data by a system from the system touch event distribution server, and carrying out touch data operation processing on the infrared touch screen by combining location data of the infrared touch screen. The invention also provides a touch data processing system for the infrared touch screen based on the pressure-sensitive pen. The touch data processing method and the touch data processing system which are provided by the invention have the advantages that the IPC way is utilized, so that the infrared touch screen can acquire the pressure data of the pressure-sensitive pen; and by combining the location 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...

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.
