Abstract:
1. A controlling device applied to a touch panel, comprising: a sampling module implemented by hardware, sampling electrical signals of the touch panel, and when at least one touch event occurs on the touch panel, generating a trigger signal corresponding to the at least one touch event; a determining module, determining whether the at least one touch event is a single-point-multi-finger gesture according to a position of the trigger signal and a number of risings of the trigger signal at the position, wherein the risings of the trigger signal correspond to sampled physical quantity; and a reporting module, reporting the at least one touch event when the determining module determines that the at least one touch event corresponding to the trigger signal is the single-point-multi-finger gesture, wherein the trigger signal comprises a first rising at a first time and a second rising at a second time, and the first time and the second time are different, and the first rising and the second rising occur at the same position.
