Overview: Using a new independent research and development algorithm to deal with the chip A80, the A80 algorithm chip can effectively identify 7 different points at the same time, the change is to better improve the anti-interference of the keyboard, so that the sensitivity and accuracy of the keyboard input are compared. The previous generation has a significant improvement. At the same time, the mouse mode also supports the enlargement and reduction of the picture in the WINDOWS7 system and the recognition of the page turning gesture. Specification 1.
