Artificial World Interface

Motion-Less VR

This research aims to implement a VR system that allows the user to freely move a virtual body without moving the real body.

Current virtual reality (VR) system uses motion capture to measure the motion of the real body and move the virtual body. In this case, however, the range of virtual space in which the user can move depends on the size of the real space, and the motion that can be performed with the virtual body is limited to that which can be performed with the real body. Therefore, we aim to realize a VR system without real body motion (Motion-Less VR) by suppressing real body motion, accurately acquiring the intention of motion, and presenting the sensation of motion.

Electric taste

This is a research of creating an artificial taste sensation through electrical stimulation.

Taste is a sensory organ with many unexplored aspects. In recent years, much research has been conducted on the use of electricity to present and change the sense of taste. If we can artificially create and freely control taste and eating and drinking experiences using electricity, we may be able to improve the quality of life in our daily lives and our sense of reality in the artificial world. Therefore, we are conducting research on increasing the salty taste and amplifying the carbonation of carbonated beverages using electrical stimulation.

Body Schema

This research is about adapting the perception of the body to an avatar in a virtual environment.

Normally, we can move our own real body freely and unconsciously. However, in a VR system, if the shape of the virtual body differs from the user's own, the operability of the virtual body is reduced. We hypothesized that the cause of this problem is the deviation of the model in the brain that remembers the body shape, called "body scheme". Therefore, we have proposed a method to adapt body scheme optimized for real body to virtual body shape, and we are currently verifying the effectiveness of this method. The method is expected to advance systems and services using virtual reality, such as remote communication and immersive operation of remote robots for medical and disaster relief.
