Abstract
The present disclosure discloses a touch key design method based on a touch screen, wherein a plastic part is placed on a touch screen, so that the touch screen is equally divided into a plurality of (such as 4×4) areas with the same size. In this way, the touch screen can be regarded as a plurality of (such as 4×4) matrix touch keys. When one of the touch keys is touched by hand, an MCU (a main control unit of a recording software controller) determines which touch key is pressed through the X and Y coordinate values returned by the touch screen, and then controls the corresponding functions. On the touch screen, not only the function name of the recording software corresponding to each touch key is displayed, but also the state of pressing or releasing the touch key and the state about whether the corresponding function on the recording software is activated or non-activated can be displayed in real time. In addition, users are allowed to change the position and the function name of each touch key in the touch screen randomly according to their own usage habits and preferences.
