Point-and-shake: selecting from levitating object displays
conference contribution
posted on 2023-06-09, 11:53 authored by Euan Freeman, Julie Williamson, Sriram Subramanian, Stephen BrewsterAcoustic levitation enables a radical new type of humancomputer interface composed of small levitating objects. For the first time, we investigate the selection of such objects, an important part of interaction with a levitating object display. We present Point-and-Shake, a mid-air pointing interaction for selecting levitating objects, with feedback given through object movement. We describe the implementation of this technique and present two user studies that evaluate it. The first study found that users could accurately (96%) and quickly (4.1s) select objects by pointing at them. The second study found that users were able to accurately (95%) and quickly (3s) select occluded objects. These results show that Point-and- Shake is an effective way of initiating interaction with levitating object displays.
