We have developed a texture display system that modifies the perceived roughness of textured surfaces via a voice coil actuator worn on the finger. To increase the roughness sensations, the vibrotactile stimuli from the actuator simulate the skin deformations that are activated when a wavy surface is scanned. Conversely, to decrease the roughness sensations of the textured surface, a high-frequency...
Augmented reality technology realizes variable sensory feedback while maintaining a high perceptual quality by superposing real and virtual stimuli. In this research, we experimentally verified whether the masking effects of high-frequency vibrotactile stimulation on fingers is applicable to augmented reality of the tactile texture of materials. A vibrotactile stimulator was worn on a finger (ring-vibrating...

In this study, we developed vibrotactile display methods that can assist designers in product design. In order to achieve realistic sensations required for such designing purposes, we used real materials such as cloth, paper, wood, and leather and applied vibrotactile stimuli to modify the roughness sensations of these materials. This approach allowed us to present textures of various virtual materials...
A vibrotactile texture display produces virtual textures by applying vibratory stimuli to finger pads. In this study, we developed a technique to alter such textures based on certain specified materials. For example, the technique allows us to alter vibrotactile textures using terms such as “wood-,” “cotton-,” or “paper-like” which are familiar to end users of displays. The altered textures feel more...
