Haptomime: Midair Touch Panel
The system enables interaction with a floating image with touching sensation, i.e. tactile feedback. The tactile feedback is presented onto a fingertip by transmitting focused ultrasound superposed on the floating image. This scheme allows for touch interaction as if pantomiming on the floating image. The liberation from a physical panel extends the use of touch interface to such situations as cooking or medical operation, where otherwise hands get smeared by a panel or the panel gets smeared by the hands.
