Demonstrating Mid-Air Ultrasound Haptics with Thermal Display

We demonstrate an ultrasound haptic-based mid-air thermo-tactile display system. We design a proof-of-concept thermo-tactile feed- back system with an open-top chamber, heat modules, and an ultra- sound haptic display. Our method involves directing heated airflow toward the focused pressure point produced by the ultrasound display to deliver thermal and tactile cues in mid-air simultaneously. We demonstrate our system with four different VR environments (campfire, water fountain, kitchen, and candle) to show the rich user experiences of integrating thermal and tactile feedback.
