Three-in-one: Levitation, parametric audio, and mid-air haptic feedback
Paper in proceedings, 2019

ACM Ultrasound enables new types of human-computer interfaces, ranging from auditory and haptic displays to levitation (visual). We demonstrate these capabilities with an ultrasonic phased array that allows users to interactively manipulate levitating objects with mid-air hand gestures whilst also receiving auditory feedback via highly directional parametric audio, and haptic feedback via focused ultrasound onto their bare hands. Therefore, this demo presents the first ever ultrasound rig which conveys information to three different sensory channels and levitates small objects simultaneously.
