Method and equipment for processing touch signal

Abstract

The invention discloses a method and equipment for processing a touch signal. The method for processing the touch signal comprises the following steps: collecting detection feature information of the shape and / or size of a touch area corresponding to a touch motion when the touch motion is detected; comparing the detection feature information with standard feature information stored in a preset database, wherein the standard feature information comprises finger feature information of the shape and / or size of a touch area touched by a finger or a touch pen, and also comprises hand feature information of the shape and / or size of other parts of a palm except for the finger; if a comparison result shows that the detection feature information is matched with the finger feature information, perform first processing on the finger feature information; and if the comparison result shows that the detection feature information is matched with the hand feature information, perform second processing on the hand feature information. The method and the equipment for processing the touch signal can effectively avoid false judgment of the touch single by a touch sensor system.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch signal processing method and device. Background technique [0002] With the popularization of computers and other electronic devices, users have higher and higher requirements for the input methods of mobile phones and tablets. They are no longer satisfied with traditional keyboard input, and gradually tend to convenient touch input. Touch sensing systems are becoming more and more popular as a means of inputting data. For example, touch-sensing systems can now be found in workshops, warehouses, manufacturing facilities, restaurants, etc., for handheld personal digital assistants, automated teller machines, and more. [0003] However, it is common in conventional touch sensing systems that it is difficult to accurately distinguish between signals based on input using a stylus, signals generated in response to a hand being placed on the touch panel, and signals gene...
