This paper presents the experimental results on the measurement of human texture perception in virtual environments. The experiment is conducted with a haptic tactile instrument that provides sensations of rough textures directly to the fingertip of the users. It consists of a brush and a DC motor. The brush rubs directly against the user's fingertip. Simulated texture is felt through an aperture...
This paper presents the design of a tactile actuator that creates rough textures directly at the fingertip of the user. The purpose of the tactile actuator is to convey varying magnitudes of surface roughness to the users. The stimulus is created by a rotating spiral brush. The results of a psychophysical experiment show that the speed of the brush is directly related to roughness perception. However,...
