ASPECT: audio spatial environment for communication As a three dimensional auditory interaction tool

A new methodology of human interface through three-dimensional virtual space created in the computer by using the audio signal is introduced. The user can access three-dimensional virtual space by her/his vocal and auditory ability. As an input function, the system contains a multiple 3-D locator which locates several 3-D pointers in the virtual space, and, as an output function, a certain type of 3-D sound generator. By showing some of the interface system, the effectiveness in the sense of direct manipulation as a spatial interaction tool can be confirmed
