A comparative evaluation of collaborative display technologies was conducted to explore their ability to support a pair of participants conducting a collaborative workspace design review. Five review media were compared: 2D CAD model on CRT, 3D CAD model on CRT, 3D CAD model on a Curved plasma display, a large DataWall display, and a CAVE environment. Participants reviewed a model depicting an in-vehicle navigation system installed within the front dash of a vehicle and detected design flaws. Performance measures (number of detected flaws and detection time) and usability measures (display, design review, and collaborative quality) were collected. The main findings were: a) flaw detection was better for 3D displays than the 2D display; b) flaws detection was progressively reduced with more immersive 3D displays; c) speed-accuracy tradeoffs were observed such that detection time was less for the 2D than the 3D displays, and decreased with the degree of immersion; d) using the standard CRT is more cost-effective than using the Curved, DataWall, or CAVE displays.
