Abstract

Many new technologies are emerging that make it possibleto extend interaction into the three-dimensional space directlyabove or in front of a multitouch surface. Such techniquesallow people to control these devices by performinghand gestures in the air. In this paper, we present a methodof extending interactions into the space above a multitouchsurface using only a standard diffused surface illumination(DSI) device, without any additional sensors. Then we focuson interaction techniques for activating graphical widgetslocated in this above-surface space. We have conducteda study to elicit gestures for above-table widget activation.A follow-up study was conducted to evaluate and comparethese gestures based on their performance. Our resultsshowed that there was no clear agreement on what gesturesshould be used to select objects in mid-air, and that performancewas better when using gestures that were chosen lessfrequently, but predicted to be better by the designers, asopposed to those most frequently suggested by participants.
