Spatial interaction in a multiuser immersive instrument.

The AlloSphere provides multiuser spatial interaction through a curved surround screen and surround sound. Two projects illustrate how researchers employed the AlloSphere to investigate the combined use of personal-device displays and the shared display. Another two projects combined multiuser interaction with multiagent systems.

Stereoscopic highlighting: 2D graph visualization on stereo displays.

In this paper we present a new technique and prototype graph visualization system, stereoscopic highlighting, to help answer accessibility and adjacency queries when interacting with a node-link diagram. Our technique utilizes stereoscopic depth to highlight regions of interest in a 2D graph by projecting these parts onto a plane closer to the viewpoint of the user. This technique aims to isolate and magnify specific portions of the graph that need to be explored in detail without resorting to other highlighting techniques like color or motion, which can then be reserved to encode other data attributes.
