Abstract
We used body sway to evaluate a viewer's sense of presence with three kinds of 3D displays as follows: a head mounted display (HMD), a 70 inch 3D display and a consumer 3D television. This expedient used images with a fixed foreground and a rolling background as the visual stimuli to induce body sway. The images were taken from a boat rolling at five different frequencies (approx. 0.125, 0.20, 0.25, 0.33, 0.50 Hz). We examined eight healthy adults viewing each of the five images for three minutes on each display. We evaluated body sway using a motion analyzing system to measure the displacement of a marker placed on the head of the subjects. It was found that at all rolling frequencies of the image background, the HMD induced the greatest amount of body sway followed by the large 3D display and then the consumer 3D television. The amount of body sway was the greatest when the rolling frequency was 0.33 Hz. The results showed the amount of body sway depended on the type of display and the rolling frequency.
