For example, the interactive tablet is specifically configured with a display screen with a touch function, and the display screen with a touch function may be an infrared display screen, a capacitive display screen, a resistive display screen, an electromagnetic display screen, a pressure-sensitive display screen, or the like. On the display screen with the touch function, a user can realize touch operation in a mode of touching the display screen by a finger or a writing pen, and correspondingly, the interactive flat panel detects a touch position and responds according to the touch position to realize the touch function. When the touch sensing modules adopted on the display screen with the touch function are different, the original touch signals collected by the touch sensing modules are different, and the converted touch signals are not completely the same.

The graphical interface displayed in the display screen of the interactive flat panel is also a touch detection area for detecting user operation, namely the ranges of the graphical interface and the touch detection area are basically overlapped.
