Analysis of head movement when viewing a wide-viewing-angle display

DOI

説明

We assumed that both viewing distance and position would be affected by the distribution of when a person viewed a high-definition image from a short distance. We measured subjects' gaze movements as they viewed an image from two viewing distances 0.75H (51cm; H is the display height), and 1.5H (102cm), as well as from three viewing positions (center, right and left). Results revealed that while there was little difference in the location of mean gazing point, it tended to gather around the display center at every viewing distance and viewing location. This tendency was indicated by the amount of head rotation, 0.75H. Although this was larger than 1.5H, when we analyzed head movement components against gaze movement components, the difference was small. It was suggested that eye movement alone resolved the enlargement of visual field caused by short-distance viewing.
