To Dwell or Not to Dwell: An Evaluation of Mid-Air Gestures for Large Information Displays

This paper investigates user preferences for mid-air gestures to interact with large public information displays. We designed and implemented a public display application that allows people to navigate between Twitter feeds and to find details about particular tweets. The application supports selection and navigation through (1) point-and-dwell and (2) push and grab-and-pull. A within-subject evaluation with 10 participants found that although point-and-dwell was perceived to be more accurate, push was preferred for selecting items and grab-and-pull was preferred for navigation. Based on our findings we derive recommendations for designing gesture-based information displays.
