Evaluation of viewing distance vs. TV size on visual fatigue in a home viewing environment

Investigating multiple human performance measures in teleoperation task: A translation task in a tele‐sandblasting maintenance system

“…As the differences in the performance measures between those two levels of VD were not significant, we conclude that both VDs Ankrum (1996) and Sakamoto et al (2009), 65 and 135 cm, respectively, provided comparable performance for this task.…”

“…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).…”

“…According to Ankrum (1996), a proper VD for a computer workstation should be equal to or longer than 25 in., and the maximum proper distance depends on the resting point of convergence. However, Sakamoto et al (2009) suggested that the best VD, which results in the least visual fatigue, lies between 3H and 4H, where H is the display height (Sakamoto et al, 2009). Adopting a bi-response design (Yuangyai, Pan, Lin, & Cheng, 2015), we set two levels of VD, illustrated in Figure 7, to study its effect on a translation task requiring hand-eye coordination.…”

“…To further investigate the system design, the effect of two design parameters, viewing distance (VD; eye-to-screen distance) and path width (PW), are considered. Although there have been reports about VD in the television context (Sakamoto, Aoyama, Asahara, Yamashita, & Okada, 2009), the effect of VD on hand-eye coordination in a translation task in a tele-sandblasting context has not been reported. Besides visual perception for a two-dimensional (2D) translation motion, PW is another critical factor, according to traditional steering law (Accot & Zhai, 1997).…”

Physiological and psycho logical measurements of emotional state using various types of video content during TV viewing

“…Bigger screens, and TV viewing styles that are becoming more diverse due to broadening content, such as video games and web pages in addition to conventional TV programs, make it increasingly necessary to consider the effects of these changes on visual fatigue and health. Our previous studies have investigated visual fatigue with the aim of proposing optimum TV viewing conditions that correspond to the content being viewed and which do not cause eye strain [1] [2]. However, measurements of users' emotional states in additional to visual fatigue are an essential element in designing and developing TVs to minimize visual fatigue while creating a sense of involvement and enjoyment.…”
