Analysis of Gazing Points while Viewing Super-High-Definition Images at Various Viewing Positions

Abstract

We conducted an experiment in which subjects viewed a 4K-resolution image shown on a big screen displayed at different viewing positions, we then analyzed gazing point at the respective positions. The study design included two viewing distances 0.75H (51cm, H is the display height) and 1.5H (102cm), and three viewing positions (center, right and left) as the parameters for subjects viewing the experimental images. Gaze movement while viewing three types of image at each of the 6 positions was measured by the viewer's eye and head movements. Results showed the distributions of gazing points were spread over the whole screen, and the locations of average gazing points were gathered in the screen center irrespective of the picture, viewing distance, or viewing position. However there was a significant difference in viewing position on the screen depending on the kind of picture, viewing distance, and viewing position as a result of 3-factor analysis of variance.
