Recent Results• Tactile Communication of Speech

– Demonstrated information transmission rate of 12 bits/sec (normal speech is 24 bits/sec)

– Slow motions and vibrations are perceptually separable for encoding speech information

• Human Responses to Motorcycle Handlebar– Constructed a handlebar vibration emulator– Human subject study is currently in progress

• Haptic Texture Perception and Rendering– Created real and virtual textures with m features

Future Directions• Tactile Communication of Speech

– Goal is to use tactile cues to supplement lip-reading– Coding schemes– User training and evaluation

• Human Responses to Motorcycle Handlebar– Goal is to predict human responses from engineering

measurements– Assessment of comfort, fatigue and annoyance

• Haptic Texture Perception and Rendering– Goal is to reproduce the feel of surface textures– Still a very long way to go
