In this paper we describe experimental measurements and comparison of human interaction with three different types of stereo computer displays. We compare traditional shutter glasses-based viewing with three-dimensional (3D) autostereoscopic viewing on displays such as the Sharp LL-151-3D display and StereoGraphics SG 202 display. The method of interaction is a sphere-shaped “cyberprop” containing an Ascension Flock-of-Birds tracker that allows a user to manipulate objects by imparting the motion of the sphere to the virtual object. The tracking data is processed with OpenGL to manipulate objects in virtual 3D space, from which we synthesize two or more images as seen by virtual cameras observing them. We concentrate on the quantitative measurement and analysis of human performance for interactive object selection and manipulation tasks using standardized and scalable configurations of 3D block objects. The experiments use a series of progressively more complex block configurations that are rendered in stereo on various 3D displays. In general, performing the tasks using shutter glasses required less time as compared to using the autostereoscopic displays. While both male and female subjects performed almost equally fast with shutter glasses, male subjects performed better with the LL-151-3D display, while female subjects performed better with the SG202 display. Interestingly, users generally had a slightly higher efficiency in completing a task set using the two autostereoscopic displays as compared to the shutter glasses, although the differences for all users among the displays was relatively small. There was a preference for shutter glasses compared to autostereoscopic displays in the ease of performing tasks, and glasses were slightly preferred for overall image quality and stereo image quality. However, there was little difference in display preference in physical comfort and overall preference. We present some possible explanations of these results and point out the importance of the autostereoscopic "sweet spot" in relation to the user's head and body position.
