Multi-point locating anti-interference processing method of touch panel positioning system

Abstract

The invention provides a multi-point positioning and anti-jamming processing method for a touch screen positioning system, which comprises the following steps: 1. when the system receives the coordinate data f a touch point, whether an anti-jamming label is placed is judged; 2. whether an anti-jamming area exists; 3. whether a timer is out of time is judged; 4. whether an effective touch area has the touch point coordinate data is judged; 5. whether the anti-jamming area has the touch point coordinate data is judged; 6. if the touch point is not in the effective touch area and the anti-jamming area, the effective touch area and the anti-jamming area, as well as the timer and the anti-jamming label are cleared away. With a wide application range, the method can handle single-point or multi-point positioning and anti-jamming occasions. When handling the multi-point interference, the method can eliminate the interference information without affecting the normal touch operation, and particularly effectively overcome the sleeve interference when the user writes on the screen, thus causing the system to work out the wrong coordinate data resulting in system chaos.

Description

technical field [0001] The invention relates to an anti-interference technology of a touch screen positioning system, in particular to a multi-point positioning anti-interference processing method of the touch screen positioning system. Background technique [0002] In today's information society, the use of computers and various electronic devices makes people's work and life easier and more efficient. As a common and simple and convenient human-computer interaction device, touch screens are widely used in various fields. In the bank, the query system with touch screen makes the information query operation more convenient and fast. In the computerized classroom, the interactive touch screen system makes the teaching more vivid and vivid, and the touch-operated game machine removes the shackles of the remote control lever or handle. , making the player's whole process more fun. Because it is only used intuitively and does not require any professional training, touch screen...

Problems solved by technology

[0003] However, when people use the touch screen, it is easy to cause interference due to the randomness of the operation, especially when writing on the screen, the normal operation of the user is affected due to habitual actions, causing inconvenience. For example, when the user writes with a hand or a pen, The sleeves often touch the screen, causing the positioning system to detect multiple coordinate data. In this case, how to determine the effective touch point and remove the interference touch point has become an urgent technical problem to be solved.

[0004] The anti-interference technology in the existing touch screen positioning system is only suitable for single-point positioning, but cannot effectively deal with the situation of multiple touch points. Therefore, when dealing with multi-touch, even if there are only two touch points, it cannot be accurately identified Its effective touch point, due to the existence of interference information, the system calculates the wrong position coordinates, resulting in the touch point is not the actual touch point, resulting in confusion in processing, which brings trouble to the user
