16 March 2021: ACM Distinguished Speaker talk by Prof Stephen Brewster

On 16 March 2021, from 9am to 10am, Prof Stephen Brewster will give a talk for the SydCHI community. We encourage everyone to join in via Zoom.

Haptics and Levitation Interfaces: The future of human-computer interaction?

Abstract of Stephen’s talk

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.

Bio of Prof Stephen Brewster

Stephen Brewster is a Professor of Human-Computer Interaction in the School of Computing Science at the University of Glasgow where he leads the Multimodal Interaction Group, which is very active and has a strong international reputation in HCI ( His research focuses on multimodal HCI, or using multiple sensory modalities and control mechanisms (particularly audio, haptics and gesture) to create a rich, natural interaction between human and computer. He pioneered the study of non-speech audio and haptic interaction for mobile devices with work starting in the 1990’s. Brewster’s work has had over 18,000 citations. He was a General Chair of CHI 2019 in Glasgow, CHI papers chair in 2013 and 2014. He is a member of the ACM SIGCHI Academy, an ACM Distinguished Speaker and a Fellow of the Royal Society of Edinburgh.

This talk is hosted as part of the Basser Seminar Series, by the School of Computer Science at the University of Sydney. Of course, everyone can join us online as Prof Brewster will join us remotely.
