“…Another intriguing finding is the enhancement of selfmotion perception with the addition of stereoscopic motion cues (Palmisano, 1996). The finding that perceived 3-D shape influences perceived heading (Beusmans, 1998) also suggests that depth information may contribute to heading perception.…”

How do we determine where we are heading during visually controlled locomotion? Psychophysical research has shown that humans are quite good at judging their travel direction, or heading, from retinal optic flow. Here we show that retinal optic flow is sufficient, but not necessary, for determining heading. By using a purely cyclopean stimulus (random dot cinematogram), we demonstrate heading perception without retinal optic flow. We also show that heading judgments are equally accurate for the cyclopean stimulus and a conventional optic flow stimulus, when the two are matched for motion visibility. The human visual system thus demonstrates flexible, robust use of available visual cues for perceiving heading direction.

“…Palmisano (1996) reported that stereoscopic presentation of moving-dot stimuli reduces the latency of vection onset and also increases the percentage of time for which observers report the sensation, relative to monoscopic presentation of the same stimuli. Palmisano's stimuli consisted of fields of randomly positioned dots which expanded outwards, simulating movement at a constant rate towards the observer, while the viewing position and projection plane remained fixed.…”

We recently reported that direct subjective ratings of the sense of presence are potentially unstable and can be biased by previous judgments of the same stimuli (Freeman et al., 1999). Objective measures of the behavioral realism elicited by a display offer an alternative to subjective ratings. Behavioral measures and presence are linked by the premise that, when observers experience a mediated environment (VE or broadcast) that makes them feel present, they will respond to stimuli within the environment as they would to stimuli in the real world. The experiment presented here measured postural responses to a video sequence filmed from the hood of a car traversing a rally track, using stereoscopic and monoscopic presentation. Results demonstrated a positive effect of stereoscopic presentation on the magnitude of postural responses elicited. Posttest subjective ratings of presence, vection, and involvement were also higher for stereoscopically presented stimuli. The postural and subjective measures were not significantly correlated, indicating that nonproprioceptive postural responses are unlikely to provide accurate estimates of presence. Such postural responses may prove useful for the evaluation of displays for specific applications and in the corroboration of group subjective ratings of presence, but cannot be taken in place of subjective ratings.

“…This kind of induced self-motion perception is called "vection". Induced selftranslation perception has been investigated by using linear motion of dots on a flat screen (Johansson, 1977;Kano, 1991;Nakamura and Shimojo, 1999;Ito and Shibao, 1999;Ito, 2004) or by using expanding flow patterns that induce forward vection (Andersen and Braunstein, 1985;Palmisano, 1996). The present study investigates a factor that suppresses vection.…”

Controlling Visually Induced Self-Motion Perception: Effect of Overlapping Dynamic Visual Noise

The effect of overlapping dynamic visual noise on visually induced self-motion perception (vection) by upward or downward optical flow was tested. The dynamic visual noise consisted of rapidly refreshed sparse random dots. Binocular disparity of the overlapping noise plane was varied. The results showed that when the noise was presented on the flow plane or on a plane farther than the flow plane, vection was totally impaired. This demonstrates that dynamic visual noise is functionally equivalent to static patterns in the vection suppression effect. A possibility of dynamic visual noise as a vection suppressor in an application on a 3-D display is discussed in relation to simulator sickness.
