Abstract
A pointing method, medium, and system detecting a synchronization signal from a plurality of light sources sequentially blinking at predetermined periods, detecting position information of the light sources by driving a video camera in synchronization with the synchronization signal, removing noise from among observed light sources by using the position information, and calculating a pointed to position by using the position information of the non-noise light sources. Provided is also a pointing reception method, medium, and system using a plurality of light sources blinking sequentially at predetermined periods, receiving the position information corresponding to light sources presenting the signals received by a pointing device and the position information pointed by the pointing device, and changing output data with respect to the pointed position information.
