“…These augmentations have an associated cost. Yeh and Silverstein (1992) have labelled these augmentations "crutches" because they clutter the display with unnatural additions. For example, drop-shadows essentially doubles the number of air track symbols in the display.…”

“…For example, Yeh and Silverstein (1992) found that the addition of stereopsis led to faster and more-accurate spatial judgments than a perspective display alone. Furthermore, Kim, Ellis, Tyler, Hannaford, and Stark (1987) examined the effect of stereopsis and perspective cues on subjects' ability to manually track an object.…”

This study investigated performance in a desktop virtual environment as a function of stereopsis and head tracking. Ten subjects traced a computer-generated wire using a virtual stylus that was slaved to the position of a real-world stylus tracked with a 6-DOF position sensor. The objective of the task was to keep the virtual stylus centered on the wire. Measures collected as the subjects performed the task were performance time, and number of times the stylus overstepped the virtual wire. The time to complete the wire-tracing task was significantly reduced by the addition of stereopsis, but was not affected by the presence of head tracking. The number of times the virtual stylus overstepped the wire was significantly reduced when head-tracking cues were available, but was not affected by the presence of stereoscopic cues. Implications of the results for performance using desktop virtual environments are discussed. IntroductionThis paper focuses on determining whether the visual cues of stereopsis and motion parallax (provided by head tracking) affect task performance when using a desktop virtual environment. In order to support training and performance in virtual environments, it is essential to provide the necessary sensory cues (e.g., auditory, spatial, or haptic) and display hardware that are required for the task. Some visual cues in virtual environments include linear perspective, binocular disparity, and motion parallax, while some hardware options include the type of display (for example, HMD, rear projection, or desktop). Note the logical relationship between display features and the availability of visual cues: the use of head tracking allows the observer to experience motion parallax, while the use of a stereoscopic display allows the observer to view stereoscopic images.Many studies have investigated the effect of adding stereopsis to a perspective display. For example, Yeh and Silverstein (1992) found that the addition of stereopsis led to faster and more-accurate spatial judgments than a perspective display alone. Furthermore, Kim, Ellis, Tyler, Hannaford, and Stark (1987) examined the effect of stereopsis and perspective cues on subjects' ability to manually track an object. Their results indicated that stereopsis improved the overall tracking performance.Another feature of desktop virtual environments is head tracking. The addition of head tracking to a stereoscopic display provides the viewer with motion parallax, which can be used to determine relative depth relations among objects (Kaiser & Proffitt, 1989;McKenna & Zeltzer, 1992). Ware, Arthur, and Booth (1993) investigated the ability of observers to perceive arterial branching in brain-scan data as a function of head tracking and stereopsis. Their results indicated that the addition of head tracking and stereopsis reduced error rates by a factor of 16 over a static pictorial display, and by a factor of 10 over a static stereoscopic display. In a related study using a similar experimental task, Rekimoto (1995) found that a stereoscopi...
