Claim Text:
1. An input apparatus of a display apparatus, the input apparatus comprising: a communication unit configured to communicate with the display apparatus; a sensing unit configured to detect an acceleration and an angular speed from a motion of the input apparatus; a storage unit configured to store position information on a position of the input apparatus; and a controller configured to calculate motion information based on the detected angular speed and the stored position information and transmit the calculated motion information through the communication unit when the input apparatus moves, and to update the stored position information in the storage unit corresponding to changes in the position of the input apparatus when the input apparatus stops moving, wherein the input apparatus is configured to pre-store waveform profiles corresponding to sensing signals of the input apparatus moving and of the input apparatus not moving, and wherein the controller is further configured to determine whether the input apparatus moves or not by comparing the profile of the waveform of the sensing signal from the sensing unit to the pre-stored waveform profiles.
