Abstract
A control signal generating method for an input device is presented. The input device includes a pointing device and a sensing device, and the pointing device sends an electromagnetic signal to the sensing device. In the method, the electromagnetic signal received by the sensing device has different strengths according to different distances between the pointing device and the sensing device. The strength of the electromagnetic signal may be further converted to a parameter. A user may adjust the distance between the pointing device and the sensing device when operating the pointing device, thereby generating a parameter to control a computer.
