One of our goals in the Levitate project is to create new types of displays using levitating objects.
These new displays use physical objects to represent information or to create user interface elements, rather than pixels on a flat screen. There are many unique properties of this type of display; for example, their display elements can be moved in three dimensions and people can see through the display, to people or objects on the other side. The following video gives an example of this:
Ultrahaptics’ core technology uses ultrasound to create haptic feedback in mid-air, with no need for gloves or hand-held controllers.
To achieve this, the amplitudes and phases of multiple ultrasound waves originating from an array of transducers (ultrasonic speakers) are modulated using patented algorithms. When controlled in this way, the waves constructively interfere and achieve a maximum pressure at a desired location in space, e.g. a user’s fingertip. The pressure is sufficient to generate tactile sensations.
