- Abstract
- We developed an improved version of midair visuohaptic virtual piano utilizing multiple ultrasonic array modules. We implemented scheduling algorithm for simultaneous generation of haptic points to increase the output efficiency. Our algorithm is based on temporal switching of modulated ultrasonic signals and player draft system on multiple ultrasonic modules. With the extended AirPiano, a user can play the virtual piano in a scene shown via the HMD and can feel the haptic points on their whole fingers while touching the keys.
