Title

An Evaluation of Methods for Linking 3D Views

Abstract

It is common for 3D visualization systems to provide multiple points of view to a user, but there have been many solutions to the problem of linking these views so that users can understand the spatial relationships between them. Toward developing guidelines for view-linking devices, we have carried out two experiments that compare the utility of three different classes of linking devices: a directional proxy, tethers from one view to another, and a track-up map coupling. The task we apply them to is what we call the multi-perspective identification task: subjects are asked to identify an item seen in a local, forward-looking view in the context of a global, overhead view. Our results indicate that the directional proxy is the most beneficial device, and that the track-up map coupling is also beneficial. The results suggest that tethers provide little benefit. The results also suggest that when multiple local views are present, it may be beneficial to emphasize one window as being of primary interest.
