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 feedback system with an open-top chamber, heat modules, and an ultrasound 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.
