Turning ultrasound into virtual touch

Here’s how it works.

1. Ultrasound speaker

It all starts with one small ultrasound speaker.

This small speaker emits ultrasound waves, which are too high a frequency for you to hear.

2. Array

We put lots of these speakers together to create an array.

Every ultrasound speaker in the array can be individually controlled.

3. Algorithms

Each individual speaker is triggered at a different time.

Using our patented algorithms, the ultrasound speakers are triggered with very specific time differences. These time differences mean the ultrasound waves arrive at the same point in space, at the same time.

4. The focal point

The place where all the ultrasound waves coincide is called the focal point.

Where the focal point is positioned in 3D space is programmable in real time. It can change position from instant to instant.

We use a hand tracking device to track the exact position of your hand and position the focal point at a spot on it.

5. Pressure point

From focal point to pressure point. Feel virtual touch come to life.

The combined ultrasound waves have enough force to create a tiny dent in your skin. We use this pressure point to create a vibration that touch sensors in your hands can detect.

By moving the pressure points around, we create tactile effects in mid-air.

We use the pressure points to create a wide range of tactile effects – from sculpting virtual lines and shapes to forming 3D controls in mid-air.
