Abstract

Computer-aided design (CAD) and 3D visualizationtechniques are at the heart of many engineering processessuch as aircraft, ship, and automobile design. Thesevisualization tasks require users to navigate or wayfindthrough complex 3D geometric models consisting ofmillions of parts. Despite numerous studies, it remainsunclear whether large-screen displays improve userperformance for such activities. We present a user studycomparing standard desktop, immersive room (i.e.,CAVE), and wall displays with 3D stereo / head-tracking,and mono / no head-tracking. We observed individualdifferences between users and found that the presence ofcontextual structure greatly impacted performance,suggesting that providing structure and developinginteraction techniques accommodating a wide range ofusers yields better performance than focusing on displaycharacteristics alone.
