Abstract
A pointer control system includes a pointer control device and a pointer sensing device. The pointer control device includes two coils. The two coils respectively transmit a first signal and a second signal to the pointer sensing device, so that the pointer sensing device senses a first coordinate and a second coordinate. The pointer sensing device outputs a control signal which is corresponding to a distance between the first coordinate and the second coordinate. Therefore, the pointer control system can use an angle formed between the pointer control device and the pointer sensing device to control the operation mode of the pointer.
