66-4: Effects of Display Curvature and Lateral Viewing Position on Spatial Presence and Image Quality for 55″ TVs

Abstract

The current study examined the effects of display curvature and lateral viewing position on spatial presence and image quality for 55" TVs. We considered four curvature-radii (2300mm, 4000mm, 6000mm, and flat) and five lateral viewing positions P1-P5 (0mm, 350mm, 700mm, 1050mm, and 1400mm from the center position). Viewing distances were fixed at 4000mm. A total of 56 participants (14 individuals per display curvature) watched 5-min video footages, each time at a randomly selected position. Spatial presence (SP) was reported on the ITC Sense of Presence Inventory (ITC-SOPI), and perceived image quality (IQ) on the Single Stimulus Continuous Quality Evaluation (SSCQE). Of all curvature × position conditions, P1 at the 4000mm curvature provided the highest SP. Across curvatures, SPs were higher at P1 and P2 than at any other viewing positions, and IQs were higher at P1 than at P3, P4, or P5. Under the assumption that one-to-five viewer conditions are equally important, the 4000mm curvature is likely to provide the highest SP, and the flat condition the highest IQ. Under an additional assumption that SP and IQ are equally important, the 4000mm curvature is likely to be the best for the one-to-four-viewer conditions, while the 6000mm curvature is for the five-viewer condition.

Curved TVs improved watching experience when display curvature radii approached viewing distances: Effects of display curvature radius, viewing distance, and lateral viewing position on TV watching experience

“…Media form factors [1] including display size, viewing distance, and image quality [2] influence watching experience by, for example, affecting geometric distortion and brilliance [3]. Display curvature radius, as a new media form factor, can increase presence [4], visual comfort [5], image quality [4], preference [6], and legibility [7], and reduce visual fatigue [8] and perceptual distortion [9]; however, it can also induce negative shape aftereffects [10,11] and longer visual processing times [12]. Herein, visual comfort is defined as the subjective impression of comfort caused by visual stimuli [13], and image quality, as an important evaluation factor for TV watching experience [14], is subjectively determined through a comparison of the displayed image and the viewer's image impression [15].…”

Wide Bezel Televisions Decrease Immersive Experiences

“…TVs are anticipated to remain the most popular home appliance for entertainment media [1][2][3][4]. As a result, many studies have been conducted on user experience (UX) to improve the satisfaction of TV users [5][6][7][8], and one critical factor involved is "telepresence" (TP). Skarbez and colleagues [9] cited Gibson [10] in their definition of the term "telepresence": "Telepresence can be thought of as the experience of one's physical environment; it refers not to one's surroundings as they exist in the physical world, but to the perception of those surroundings as mediated by both automatic and controlled mental process [10]: telepresence is defined as the sense of being in an environment.…”

Effects of display curvature and hand length on smartphone usability

“…Some advantages of curved display over flat display have been reported, but these were mostly for large curved display products such as TVs or monitors (e.g. Park et al, 2017;Park et al, 2015;Choi et al, 2015;Park et al, 2016;Na et al, 2016). On the contrary, studies on small curved display products are very limited.…”
