LK-013 Lightness Influence on Virtual Haptic Roughness Perception

概要

It is very natural for us to interact with computers using multimodal interfaces, as we do in real life. Haptic (tactile) human-computer interaction (HCI) is considered to be a promising approach among them with its unique bi-directional nature. To investigate lightness influence on virtual haptic roughness perception of textured surfaces, the authors conducted some experiments, via a PHANToM force feedback device. It is better to use a high level of lightness when perceiving haptic textured surfaces because we have found that (1) the percentage of correct answers of virtual haptic roughness judgment was higher when the haptic textured surfaces had a higher lightness. Furthermore, a left-right haptic textured surfaces layout is recommended over an up-down layout when using PHANToM because we found that (2) participants tended to perceive the lower haptic textured surface as rougher when judging the roughness of two textured surfaces with an up-down layout interface. We also found that (3) different roughness was perceived for textured surfaces with sinusoidal grating numbers of 25, 28, 32 and 35 per 300 mm.
