Abstract

PURPOSE:To easily input three dimensional information at a low cost without the specific influence to a human body by a method wherein four or more microphones detecting a sound are fixed at a prescribed distance and a position of a sound source is determined based on the differences of the sound detected by the microphones. CONSTITUTION:A microphone 1 which is a standard one for a normal position of a sound source and other microphones 2-4 are connected at a prescribed distance by supporting rods 2a-4a. A sound source normal position operation section 5 determines the position of the sound source where the sound is generated on the basis of a sound pressure detected by the microphone 1. Since the sound pressure is in inverse proportion to the square of a distance from the sound source, the coordinate of the sound source in a three dimensional rectangular coordinate system is calculated based on the difference between the sound pressure values detected by the respective microphones 2-4 and the sound pressure value detected by the microphone 1. A computer 6 determines a moving direction of a pointer 7 in a three dimensional virtual space on the basis of the coordinate of the sound obtained by the operation section 5. Thereby, it is possible to operate the pointer 7 in the three dimensional virtual space by holding and moving the microphone along with vocalizing.

2. Description of the Related Art When inputting three-dimensional information to a computer or the like, for example, when moving a pointer in a three-dimensional space virtually created by the computer, 2
Devices such as a mouse and digitizer that can input dimensional information are used for natural expansion. For example, there are a glove type “data glove” in which a magnetic sensor is embedded, a suit type “data suit”, and a “flying mouse” capable of pointing in space.
These move a magnetic sensor in the presence of a magnetic field formed around it, and the change in the output of the magnetic sensor due to this detects the state of movement of a "data glove" to which this magnetic sensor is attached. It is output as position information in the dimensional space.
