“…Although several studies discussed the effect of VD on blinking rate, heart rate variability (level of sympathetic nerve activity: LF/HF), and task performance (watching and answering about TV shows; Sakamoto et al, 2009). Sakamoto, Aoyama, Asahara, Yamashita, and Okada (2008) reported that the optimal VD lies between 3 and 4 times the display height (Sakamoto et al, 2008). In contrary, Ankrum (1996) suggested that the proper VD for a computer workstation was at 25 in.…”

In sandblasting tasks for complex steel structure maintenance, teleoperation is required to keep humans away from occupational risk and hazard. On the other hand, teleoperation typically degrades system‐human performances, resulting in poor product quality and must be designed such that the performances remain as high as possible. However, designing the teleoperation system regarding to a single performance measure may lead to an improper design. In this article, we propose two novel loss‐function‐based human‐performance measures to incorporate with a widely used performance measure, movement time, to thoroughly represent performance: unfinished surface and damaged surface. We aim to investigate the effects of two main design parameters, viewing distance and path width. The results show that only path width is significant for overall performances. Furthermore, the effect of gender is significant such that men outperform women in cleaning the surface. Finally, the optimal setting conditions are suggested to achieve their optimal performances.

“…TV watching experience comprises diverse elements. In previous studies on TV watching experience, presence [1,[16][17][18][19], visual comfort [20][21][22][23][24][25][26], image quality [17,27,28], satisfaction [26], visual fatigue [26,[29][30][31], motion sickness [16], empirical 3-dimensional (3D) image distortion [21], and emotional reactions [28] were considered. User satisfaction is used to explain the overall quality of experience with visual display products.…”

“…Although presence increases as viewing distance decreases, it can suffer at excessively short viewing distances [36,37]. Studies on non-high definition (HD) flat TVs have involved viewing distances of 2-14 W [38,39] and 5 H [40], where W and H respectively represent display width and height, whereas HD TV studies have used shorter viewing distances (3-4 W or 0.8-6 H) [27,[41][42][43][44][45][46]. No study, however, has addressed the interactive effect of viewing distance and display curvature radius on TV watching experience.…”

Although watching TV often involves multiple viewing distances and viewers, less attention has been paid to the effects of display curvature radius, viewing distance, and lateral viewing position on TV watching experience. This study examined the effects of four display curvature radii (2300R, 4000R, 6000R, and flat), two viewing distances (2.3 m and 4 m), and five lateral viewing positions (P 1-P 5 ; 0, 35, 70, 105, and 140 cm off-center) on seven TV watching experience elements (spatial presence, engagement, ecological validity, negative effects, visual comfort, image quality, and user satisfaction). Fifty-six individuals (14 per display curvature radius) were seated in pairs to watch videos, each time at a different viewing position (2 viewing distances × 5 paired lateral viewing positions). The spatial presence and engagement increased when display curvature radius approached a viewing distance and lateral viewing position approached P 1 , with 4000R-4m-P 1 (display curvature radius-viewing distance-lateral viewing position) providing the best results. Lateral viewing position alone significantly affected five TV watching experience elements; the spatial presence and engagement decreased at P 3-P 5 , and ecological validity, image quality, and user satisfaction decreased at P 4-P 5. However, display curvature radius alone did not appreciably affect TV watching experience, and viewing distance alone significantly affected visual comfort only, with a 4-m viewing distance increasing visual comfort. This study demonstrated that effective display curvature radii for watching TV are viewing distance-dependent, and less off-center lateral viewing positions (P 1-P 2) are recommended for TV watching experience. Finally, among the TV watching experience elements, engagement explained user satisfaction to the greatest degree.

This study explored the effect of TV size, light source, and ambient illumination on the preferred viewing distance of portable liquid‐crystal‐display televisions. Results showed that the mean preferred viewing distance was 1389 mm. TV size had significant effects on preferred viewing distance. The larger the screen size, the greater the preferred viewing distance, at around 6.7–14.7 times the width of the screen (W). Light sources revealed no significant effect on preferred viewing distance. The effect of ambient illumination on preferred viewing distance was significant. The higher the ambient illumination was, the longer the preferred viewing distance.
