“…Small groups of users gather around the table, and can interact concurrently with the information displayed on the surface, smoothly going back-and-forth between personal and group activities. Application areas include crisis management and emergency response [26,17], scientific data analysis [36], simulation training [5,6], architecture and urban planning [19], complex system monitoring and management [20,29]. Multi-scale navigation interfaces play an important role in the exploration of these visual information spaces, as the latter are typically much larger than what can fit on one screen.…”

Multi-scale navigation interfaces were originally designed to enable single users to explore large visual information spaces on desktop workstations. These interfaces can also be quite useful on tabletops. However, their adaptation to co-located multi-user contexts is not straightforward. The literature describes different interfaces, that only offer a limited subset of navigation actions. In this paper, we first identify a comprehensive set of actions to effectively support multi-scale navigation. We report on a guessability study in which we elicited userdefined gestures for triggering these actions, showing that there is no natural design solution, but that users heavily rely on the now-ubiquitous slide, pinch and turn gestures. We then propose two interface designs based on this set of three basic gestures: one involves two-hand variations on these gestures, the other combines them with widgets. A comparative study suggests that users can easily learn both, and that the gesturebased, visually-minimalist design is a viable option, that saves display space for other controls.
