c touch interactive display.Generally, the coordinates of the fingers are transmitted to the system , and then the system recognizes gestures by software programs.Although it is feasible, the response speed is slow , especially when multi-finger touch or hand input is more obvious , and when the X , Y axis signals When disturbed by external noise , the coordinate information will be more unreliable , which will cause difficulty in gesture recognition , making more complex gestures impossible to support . Like the iPhone , only slide and Zoom-in / Zoom out actions will be supported . In addition to the current scanning mode ( infrared or projected capacitive or build X- , the Y -axis by scanning ), in order to reduce the number of scanning lines are taken so-called Load Grounded practice , this approach would result in a different coordinate-finger , and With only one identical coordinate , the system is not recognizable. And other extra signals can be used in the IC to assist judgment .This additional signal usually results in different integration difficulties due to different algorithms.
