EBVchips - Epaphus

Epaphus creates the sense of touch in mid-air without the need for gloves,wearables or hand-held devices. For the first time, gesture recognition has feedback without a physical connection. It is responsive and reactive. The core technology uses ultrasound to project "sensations" onto your hand , allowing you to feel what`s not there. Through a combination of ultrasonic transducers and an agnostic tracking device, coupled with unique algorithms, users can control buttons, switches and sliders, interact with 3D shapes and feel textures, when and where they need them.
