Abstract:
A wireless input apparatus comprising:an entry unit for use in input operation; and a processing unit for performing a process of generating data associated with an operation to the entry unit, the entry unit and the processing unit being connected to each other via a wireless communication channel, the entry unit including: an operation detecting section for detecting a start and end of input operation; and a signal transmitting section for transmitting an operation signal via the wireless communication channel at a time when the operation detecting section detects a start of input operation and at predetermined intervals from the time of detection of the start of the input operation to a time when the operation detecting section detects an end of the input operation, the processing unit including; an end-of-operation judging timer for measuring a threshold time which is set to be longer than the predetermined interval of the signal transmitting section of the entry unit; a signal receiving section for receiving a signal transmitted from the signal transmitting section of the entry unit via the wireless communication channel; and a processing section for recognizing an input operation and causing the end-of-operation judging timer to start measuring a threshold time when the signal receiving section receives the operation signal, and when the measurement of the threshold time by the end-of-operation judging timer is ended, recognizing an end of the input operation and generating data in accordance with a recognition result.
