Ultrahaptics uses ultrasound to create and manipulate focused points of high acoustic pressure. These Control points can be moved around in real-time to interact with our hands to create a sensation. The surface of the hands are covered with sensitive nerve endings called mechanoreceptors. Because these are not sensitive to a constant high pressure the control points are manipulated, either by moving them – Spatio-Temporal Modulation – or changing their intensity with a lower frequency wave – Amplitude Modulation.
You can read more about tactile sensations, mechanoreceptors and how they relate to our technology here.
The Leap Motion® camera module, or any third part tracking system, provides the position of the hands and fingers. Combined with Ultrahaptics’ API, the control points can be moved around to follow the hand, creating patterns and sensations.
