The new optical device ‘DCRA’ can display floating images in free air1). The images are undistorted and can be observed at close range from different angles, thus they are suitable for hands-on interaction. However, the current device allows only small images and movement of objects can be difficult to recognize. It is known that combining sound with vision can enhance position sensing. We have investigated ways to place aerial sound sources inside the floating images, and developed a system using parametric speakers as a virtual aerial sound source. Our tests confirm that human position recognition is effective with this system.
