Humans receive various types of information from multiple sensory receptors, which are processed by the brain to help us understand the events around us. However, since the brain attempts to integrate sensory information in a way that is consistent with our past experiences, it can sometimes lead to a phenomenon known as cross-modality. This occurs when the brain receives contradictory sensory information, causing some sensory information to be complemented or suppressed, and can result in the perception of stimuli that were not actually present. In this research, we are studying technologies that can create new sensory presentations and experiences using cross-modality, not only for vision and touch, but also for other senses such as taste and somatosensory perception.

We are conducting applied research on VR/AR technology with the aim of supporting various aspects of daily life, such as promoting health through enjoyable walking experiences, making it easy to see and remember timetables that are too far away to read clearly, helping users choose a shirt that matches their favorite pants when shopping online, and enabling users to enjoy VR games without experiencing motion sickness. Our goal is to develop practical applications that can enhance people's lives.

We have developed a system that authenticates the person tapping the screen of a smartphone with a single tap. By implementing this technology, it may be possible to create a "purchase button" or a "send button" for emails that can only be activated by the user themselves. We are also researching other recognition technologies to understand how people interact with their mobile devices, such as how they hold and position their smartphones, and whether they are feeling drowsy.
