Publication: A Comparison of Techniques for Multi-Display Reaching

Recent advances in multi-user collaboration have seen a proliferation of interaction techniques for moving digital objects from one device to another. However, little is known about how these techniques work in realistic situations, or how they compare to one another. We conducted a study to compare the efficiency of six techniques for moving objects from a tablet to a tabletop display. We compared the techniques in four different distance ranges and with three movement directions. We found that techniques like the Radar View and Pick-and- Drop, that have a control-to-display ratio of 1, are significantly faster for object movement than techniques that have smaller control-to-display ratios. We also found that using spatial manipulation of objects was faster than pressure-based manipulation.

Advanced Interaction for Multi-display Environments
Multi-display environments (interfaces composed by several display surfaces) have the potential to dramatically change the way that we work with digital information: for example, they provide a variety of work surfaces to fit different kinds of tasks, they provide a very large visual bandwidth, they enable the use of peripheral attention space, and they naturally support co-located collaboration.
