ABSTRACT:
Electromagnetic signals are sent between a base station and a human interface device (HID). Movements of the HID are detected according to an amount of time required for the electromagnetic signals to return back from the HID. In one embodiment, the electromagnetic signals are radio frequency (RF) waves carrying one or more pulses that are sent by multiple antennas in the base station and returned back from multiple antennas in the HID.
