Mid-Air Gestural Interaction with a Large Fogscreen

Abstract

Projected walk-through fogscreens have been created, but there is little research on the evaluation of the interaction performance with fogscreens. The present study investigated mid-air hand gestures for interaction with a large fogscreen. Participants (N = 20) selected objects from a fogscreen using tapping and dwell-based gestural techniques, with and without vibrotactile/haptic feedback. In terms of Fitts’ law, the throughput was about 1.4 bps to 2.6 bps, suggesting that gestural interaction with a large fogscreen is a suitable and effective input method. Our results also suggest that tapping without haptic feedback has good performance and potential for interaction with a fogscreen, and that tactile feedback is not necessary for effective mid-air interaction. These findings have implications for the design of gestural interfaces suitable for interaction with fogscreens.

A Comparison of One- and Two-Handed Gesture User Interfaces in Virtual Reality—A Task-Based Approach

“…There has been a lot of research related to analyzing 3D user interfaces in the past, and the terms tangible or graspable interface are mentioned frequently, referring to digital interfaces which are interactable via the physical dimension in some way [10][11][12][13], e.g., a computer mouse using a personal computer. Some UI-focused studies include objectgrabbing with HT (mid-air grabbing) in VR, e.g., [14] or selecting objects from interactive displays and surfaces [15][16][17]. A lot of the research on gesture usage is empirical (by nature) [12,18] and in some cases, it has been influenced by concepts such as VR animation design [19].…”
