摘要： PROBLEM TO BE SOLVED: To listen to plural sounds at the same time from different directions by locking sound image of plural pieces of sound information and putting them together. SOLUTION: A sound image localization processing process 111 is provided in a virtual sound space generation part 110 and on the basis of a virtual user position 101 or virtual sound source position 102 set by a virtual sound space definition part 100, sound images of plural pieces of sound information are localized in a virtual sound space. Further, a user position and operation measurement part 21 and a user head direction measurement part 22 are provided and a user selects sound information intuitively and sensually. Further, a message transfer part 50 capsules the sound information that the user selects and a process for the sound information into a message 51 and transfers the message 51 to a proper processing means. Further, the processing means which is not at the virtual sound space definition part 100 generates the sound information itself. The processing means, e.g. an electronic secretary 60 is selected, a command or data from the user are sent, and the processing result is outputted as a synthesized sound by a sound synthesis part 63 to a virtual sound space generation part 110.
