I am a doctoral student doing research on cross-modal interfaces with Prof. Narumi and Prof. Lécuyer at Cyber Interface Lab, the University of Tokyo, Japan. 

Realize The Ultimate Display by Cross-Modal Approach
My research goal is to realize “The Ultimate Display” (Sutherland, 1965) where "the computer can control the existence of matter." With the ultimate display, people can feel and interact with virtual objects as a "real" one. Specifically, I have been working on cross-modal haptic techniques since my bachelor’s research. Cross-modal haptic technique is a technique that enables the modification of haptic perception by appropriately changing (audio-)visual feedback to body movements using the interaction of sensory information in the cognitive process. Cross-modal haptic presentation has attracted much attention, especially in the fields of virtual reality (VR) and user interfaces, because it can present haptic sensations without bulky devices. However, it has been pointed out that the cross-modal haptic presentation method also has large individual differences in the intensity of occurrence, because the sensory integration has individual differences caused by differences in sensory characteristics and their experience. To solve this problem, my research currently focuses on clarifying a method for precisely manipulating the contribution ratio of each sensory information in the sensory integration. I believe that this method enables a robust cross-modal haptic presentation that can ignore the effects of individual differences.
