Patent ID: 8629835

Claim:
An input device, comprising: a touch sensing unit to sense a touch on the input device and to generate a first sensing signal with respect to the sensed touch; a motion sensing unit to sense a motion of the input device and to generate a second sensing signal with respect to the sensed motion; an input signal generation unit to generate an input signal based on the first sensing signal and the second sensing signal; and a transmission unit to transmit the input signal to a display device, wherein the display device controls an object displayed on the display device based on the input signal, when the input signal is received, wherein the sensed touch of the input device is a touch between a user and the input device, wherein the touch sensing unit senses another touch between the input device and ground when the input device touches the ground, and wherein the input signal generation unit determines that the input device is not in contact with ground when the another touch is not sensed by the touch sensing unit.
