Gestures for Large Display Control
The hands are highly suited to interact with large public displays. It is, however, not apparent which gestures come naturally for easy and robust use of the interface. We first explored how uninstructed users gesture when asked to perform basic tasks. Our subjects gestured with great similarity and readily produced gestures they had seen before; not necessarily in a human-computer interface. In a second investigation these and other gestures were rated by a hundred subjects. A gesture set for explicit command-giving to large displays emerged from these ratings. It is notable that for a selection task, tapping the index finger in mid-air, like with a traditional mouse, scored highest by far. It seems that the mouse has become a metaphor in everyday life.
