Outline of Final Research Achievements

We propose a remote and noncontact haptic texture measurement system. Our system is based on the ultrasound reflection and interference. We confirmed following fundamental technologies. 1) We constructed the physical model of the ultrasound reflection and interference. 2) We implemented the simulation program of the reflection wave distribution. 3) We conducted the measurement of the ultrasound reflection wave distribution. The results are consistent with our physical model. 4) We numerically confirmed that the original surface geometry could be solved based on the reflection wave distribution.
