UltraHaptics: Multi-Point Mid-Air Haptic Feedback for Touch Surfaces

Published and presented at UIST ’13 Authors: Tom Carter, Sue Ann Seah, Benjamin Long, Bruce Drinkwater, Sriram Subramanian We introduce UltraHaptics, a system designed to provide multi-point haptic feedback above an interactive surface. UltraHaptics employs focused ultrasound to project discrete points of haptic feedback through the display and directly on to users’ unadorned hands. We investigate the desirable properties of an acoustically transparent display and demonstrate that the system is ca
