摘要

PROBLEM TO BE SOLVED: To enable easy input to and output from the information processor at low cost from a remote place. SOLUTION: A personal computer 10 and a sound transmitter receiver 20 send and receive audio signals of high audio frequencies. The personal computer 10 receives a signal by a microphone 102 as an input signal of the personal computer 10 and outputs a sound output signal from a speaker 101. The personal computer 10 is controlled with the output of the speaker 201 of the sound transmitter receiver 20. Further, a microphone 202 receives the sound signal from the personal computer 10 and displays information included therein on a display unit 204. Consequently, only the sound transmitter and receiver 20 is prepared as hardware and signals can be inputted to the personal computer 10 at a distance from the personal computer 10.
