ABSTRACT

Despite the many challenges understanding how best to interact with large format displays, they are becoming increasingly popular for data analysis tasks in a variety of domains, including scientific, information, and geo-visualization. (Figure 1a shows a relatively small, 60" display; even larger, wall-size displays are also popular.) In order to make the most effective use of the full display, users typically stand and walk around in these environments. In fact, this physical navigation has been shown to be beneficial in data analysis tasks [1]. Since immobile input devices, such as mice, keyboards, or pen-tablets, do not naturally support interaction "on the move", new interactive techniques are needed to facilitate fluid interaction across a range of distances when working with large-format displays. We believe body-centric 3D, gestural input is particularly promising in this regard. Our work investigates techniques for reliable menu selection based upon these ideas, introducing new 3D input strategies for controlling menus. Our work builds upon previous techniques, such as rapMenu [3], which uses rotational hand movements and finger pinches to control menus from a distance.
