“…From the floor, the screen center was at a height of either 110 cm (roughly at the eye level of a seated participant) or 140 cm, and the viewing direction was either frontal or 30° to the right. The viewing distance was set to the optimum distance 4H [3] for the 58-in. display, which corresponds to 4 times the screen height.…”

This paper summarizes the results of an investigation on the viewing angle requirements for large flat-panel television displaysas well as on screen tilting as a means of reducing glare in accordance with the "Ergonomic Design Guidelines for Flat Panel Display Televisions" established by a special committee of the Japan Ergonomics Society. First, taking into account screen size, we investigated viewing angle requirements through a field survey of household television viewing conditions. We then evaluated the influence of the size, mounting height, and tilt of the screen on the occurrence of glare. Next, we conducted laboratory experiments to investigate the allowable tilt angle for ensuring acceptable viewing comfort and the optimum screen tilt angle for each mounting height. The results can be used as guidelines for adjusting viewing conditions as well as for ergonomic design of flat-panel television displays.

“…In high-definition, the entire screen is displayed, and the viewers' gaze points are spread over the entire screen. Several research groups have verified the differences in viewing distance by using parameters such as screen size, display brightness, resolution, and video content [5][6][7][8]. In those studies, the contents were viewed from the center position of the display, and the viewing position was not changed in the horizontal or vertical direction.…”

Ultra-high resolution broadcasting such as 4K and 8K are becoming more popular for athome use. The position of the viewer's mean gaze point when they are looking at a larger display depends on the video clip, viewing position, and viewing distance. The International Telecommunication Union provided the document BT-2022; as the standard viewing conditions for the subjective evaluations of flat-panel TV displays. However, it is rare that a television is viewed at home under standard viewing conditions. In most homes, a TV of any size is watched from the viewer's desired position according to the layout size of the room hosting the TV. No study has been conducted to determine how the movement of a viewer's line of sight changes when a display with different resolution is viewed from a position different from the standard viewing condition. If the gaze position when viewing TV differs due to the difference in resolution, the size of the display, and the difference in observation position, it affects the method of TV production. This would also affect consumers considering the resolution, installation location, and viewing location of a TV. Here, we clarified that the mean gaze position and its standard deviation are almost the same viewing conditions (i.e., resolution, display size, and viewing position) are changed, even when the same contents are viewed. Our findings demonstrate that consumers could buy a display of their preferred resolution and size according to their room layout.
