"This project demonstrates an innovative tactile display that radiates airborne ultrasound and produces high-fidelity pressure fields with multiple ultrasound transducers based on wave-synthesis techniques. Airborne ultrasound can be applied directly onto the skin without the risk of penetration. Tactile feedback is provided to the users' hands without requiring the use of gloves or mechanical attachments. "
