Electronic pen position state detection method and device

Abstract

The invention provides an electronic pen position state detection method applied to an electronic pen. The method comprises the following steps of: acquiring infrared light output by infrared touch equipment; sending first identification information and pressure information to the infrared touch equipment, sending the first identification information and the pressure information to the infrared touch equipment to enable the infrared touch equipment to acquire position state information of the electronic pen suspending on a display screen according to the first identification information and the pressure information; wherein the first identification information is confirmation information generated when infrared light output by infrared touch equipment is received, and the pressure information is information generated by mutual extrusion between the electronic pen and the display screen. The embodiment of the invention further provides the electronic pen position state detection methodapplied to the infrared touch equipment and a corresponding device. According to the invention, the electronic pen is used for collecting infrared light sent by the infrared lamp on the induction infrared touch equipment, so that the relative position between the electronic pen and the display screen is obtained. Whether the electronic pen is suspended on the display screen is determined.

Description

technical field [0001] The present application relates to the field of human-computer interaction, in particular to a method and device for detecting the position and state of an electronic pen. Background technique [0002] With the improvement of the level of technology and the quality of life, more and more smart devices appear in people's daily work and life, and touch devices are one of them. People can directly operate on the display screen by touching the device, without a mouse or other devices for wired or wireless operations, which is convenient and quick. At the same time, writing devices that can write on touch devices also emerged as the times require. By using the writing device, people can freely write on the touch device like using a pen. [0003] Infrared touch devices are currently the most commonly used touch devices on the market and in work and study. The infrared touch device is provided with a frame containing infrared lamps on the outer edge of the...

Problems solved by technology

In this case, it appears that there is contact between the writing device and the display, but not enough for the pressure sensor to detect pressure

In this way, the effective connection and communication between the writing device and the touch device cannot be realized, and the handwriting cannot be displayed on the display screen, resulting in the failure of the user to use normally and reducing the user experience.
