Latest Patents

Ujitoko’s listed patents focus on controlling visual cues to create tactile impressions.

- Softness Feeling Control Device, Softness Feeling Presentation System, Softness Feeling Control Method, and Program. This invention maps a user-designated softness impression to a deformation speed for a visual target. Presenting the target deforming at that speed can evoke the intended impression of softness.

- Apparent Force Control Device, Apparent Force Presentation System, Apparent Force Control Method, and Program. This invention vibrates a second visual object, positioned in contact with or near a first object, using a specific control-frequency component. The vibration is designed to make an apparent force seem to act from the second object on the first.
