Ultrasound Haptics
The HaptiRead device includes 256 ultrasonic transducers – tiny speakers that emit ultrasound waves in the direction of the user’s hand. It has been designed that gives blind people the sensation of reading Braille, without having to touch any surfaces.
The Emerge Wave-1 is a new ultrasound-powered tabletop device that brings touch and emotion to VR applications.

Description
Haptic sensations are transmitted to the skin through precisely focused sound waves, so multiple points of stimulation can be created and moved without the constraints imposed by a physical end effector. These sensations can cover a wide range, stimulating all of the hand, for example, within a relatively large workspace. Finally, high sample rates and the speed of sound enable a high degree of temporal precision, which can lead to novel tactile sensations that are not possible with some alternative technologies (Rakkolainen, 2020).
