Sound image presented media system

　In order to support the creation of physical expression, the media which produce sounds from the motions of a person has already been developed in many places, but there aren't any sound media that focuses on the existing position of the body. Therefore, in the present study, we aim to develop a sound media system which relates to the existing position of the person. Specifically, we try to support the locational image creation by changing the presented sound with the position of a person.
　In this system, in order to present a sound image locally for any position, we are using the parametric loudspeaker with a sharp directivity. We enabled sound track to the person by acquiring the location information of the person by using the Kinect of Microsoft Corporation and performing volume control for the speakers based on this location.

　Further, we also tried to support creation of new physical sensations by combining the shadow media (double afterimage shadow media). Specifically, it is the sound media which generate inner and outer parameter of persistent shadow and orient the sound image to each center of brightness balance.

Sound spatial representation system stereotactic possible on the body

　The current sound image orienting system cannot orient sound image to any position of body yet. Therefore, it has not yet reached to create the sensation of manipulating sound in body sites own by reflecting the sound on the point of body like hands or feet following their movement. In this study, we thought we could orient wound image by reflecting ultrasonic speaker on body parts. Specifically, by getting the three dimensional position of body with range and image sensor and controlling the oscillating unit of the ultrasonic speaker, we made it.
