<p>PURPOSE:To generate a control signal efficiently in response to a kind of a sensed hand action by providing a transmitter at a finger tip, and a receiver at a part of a hand and analyzing a received signal so as to decide a relative position of the finger tip. CONSTITUTION:Transmitters 1-5 each transmits a radio wave with an independent frequency, a receiver 6 gives a received signal to a signal amplifier section 7 and it gives the signal after being amplified to a component decomposing section 8, in which the signal is decomposed based on a reference signal generated from a reference signal generating section 10 based on each frequency component. The decomposed frequency signal is fed to a relative position coordinate analysis section 9, in which the phase of each decomposed frequency signal and the phase of the signal from the reference signal generating section 10 are detected and a distance between each of the transmitters 1-5 sending each component signal and the receiver 6 is analyzed depending on the quantity of the phase difference. An distance data signal as the result of analysis is outputted from a signal output section 11. Furthermore, the reference signal generating section 10 oscillates five kinds of signals whose frequencies differ and the signals are fed respectively to the transmitters 1-5, the component decomposing section 8 and relative position coordinate analysis section 9.</p> |
