“…Negative effects describe adverse physiological reactions, including dizziness, nausea, headache, and eyestrain [73]. The first four variables are sub-concepts of presence [73], and were assessed using 13 items selected from the Independent Television Commission-Sense of Presence Inventory (ITC-SOPI): three regarding spatial presence (Q7, 9, 18), three regarding engagement (Q2, 8, 16), three regarding ecological validity (Q5, 11,27), and four regarding negative effects (Q14, 21,26,37). Each item was rated on a 5-point Likert scale (0: strongly disagree, 1: disagree, 2: neutral, 3: agree, 4: strongly agree), and the mean item values of each sub-concept were used in statistical analyses.…”

“…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.…”

“…Thus far, many TV watching experience elements have been considered: presence [16,19], visual comfort [24,26], image quality [17,28], satisfaction [26], visual fatigue [26,29], motion sickness [16,57], image distortion [21], and emotional reactions [28]. The spatial presence felt by a display user can act as a predictor for user satisfaction [58].…”

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.
