Ultrasound haptics and levitation: the future of human-computer interaction

Speaker:  Stephen Brewster – Glasgow, United Kingdom
Topic(s):  Human Computer Interaction


Ultrasound provides some brand new opportunities for interaction in user interfaces. In this talk, I will describe this new modality and what it offers to HCI. By using standard loudspeakers, we can create soundfields that generate haptic feedback in mid-air, without the user having to hold or touch anything. We can control the position and texture of this feedback in real time. This ‘mid-air’ haptics enables new interaction techniques around devices. I will give examples of how it can be used for virtual controls and how novel interactions can be designed. Another exciting possiblity is the use of ultrasound to levitate small particles to create ‘physical’ pixels in the air in front of the user. These physical pixels can be precisely controlled to levitate 3D shapes and objects, which can be controlled dynamically. This opens up many exciting opportunities for displaying 3D models and data. In the talk, I will describe how to make this highly novel form of display possible and some of the interesting problems that arise around selecting and manipulating the levitated objects.
