Claim 8:
9. An electronic device comprising a memory, a processor, and a computer program stored on the memory and executable on the processor, wherein the processor, when executing the computer program, implements an infrared touch scanning method comprising:
grouping transmitting lights located on a frame of an infrared touch screen to obtain at least two transmitting light groups;
setting at least two scanning modes and setting one of the scanning modes as a basic scanning mode, wherein each of the scanning modes corresponds to at least one of the transmitting light groups and the scanning modes each correspond to different numbers of transmitting lights;
establishing a corresponding relationship between the at least two scanning modes and a writing speed, wherein the faster the writing speed, the less the number of the transmitting lights corresponding to the scanning mode associated with the writing speed;
performing a scanning using the basic scanning mode to determine a current writing speed of a user;
determining a corresponding scanning mode from the scanning modes according to the corresponding relationship and the current writing speed of the user; and
performing a scanning using the determined corresponding scanning mode.
