We propose a stereoscopic vibration display that localizes external vibration sources, a tactile version of the stereophonic sound. We innovate the conventional haptic phantom sensation in two ways. First, we develop a stereo display technology that localizes vibration sources not only on the body but also at arbitrary locations in the external world. Second, we will develop a technology to experience vibration sources silently by using a vibration signal modulation technology that can handle arbitrary high-frequency vibrations, including the auditory range, instead of simple stimuli such as sine waves.　We aim to improve the sense of presence and realism by expressing the sensation received from a vibration source or a sound source at a specific distance and direction in the external world. In addition to the development of the fundamental technology for stereoscopic vibration displays, we will examine the perceptual change of stere localization and attention guidance to objects by integrating stereophonic sound and visual stimuli. The outcome will be available as a basic technology for general-purpose tactile displays that can be widely used in the deep SHITSUKAN field.
