“…Typically, presbyopia, age-related reduction in accommodative amplitude, starts developing at the age of 40, and it causes the visual system to become easily fatigued (Eskridge, 1984). As the number of people over the age of 40 is expected to increase globally (2015: 35%, 2030: 41%; U.N. Department of Economic and Social Affairs, 2015) and presbyopic individuals are likely to perform VDT tasks, studies on visual fatigue in this group are important (Y. T. Lin, Lin, Hwang, & Jeng, 2008).…”

Objective: This study examined the effects of display curvature, presbyopia, and task duration on visual fatigue, task performance, and user satisfaction. Background: Although curved displays have been applied to diverse display products, and some studies reported their benefits, it is still unknown whether the effects of display curvature are presbyopia-specific. Method: Each of 64 individuals (eight nonpresbyopes and eight presbyopes per display curvature) performed four 15-min proofreading tasks at one display curvature radius setting (600R, 1140R, 4000R, and flat; mm). Diverse measurements were obtained to assess visual fatigue, task performance, and user satisfaction. Results: The mean pupil diameter was the largest with 1140R, indicating this curvature radius was associated with the least development of visual fatigue; 600R was comparable with 1140R in terms of pupil diameter. The presbyopic group showed a 28.5% slower proofreading speed compared with the nonpresbyopic group, whereas their proofreading accuracy was comparable. For both groups, the mean visual fatigue increased significantly during the first 15 min of proofreading, as indicated by a decrease of 0.11 mm in the mean pupil diameter, an increase of 3.8 in the mean bulbar conjunctival redness, and an increase of 9.13 in the mean eye complaint questionnaire score. Conclusion: The effect of display curvature was not presbyopia-specific. Low visual fatigue was observed with 1140R and 600R. Application: Display curvature radii near or in the range of 600R and 1140R and frequent breaks are recommended for both presbyopic and nonpresbyopic groups to reduce their visual fatigue due to visual display terminal tasks.

This study investigated the effects of age group, interface type, and key area on accuracy, usability, the change of critical fusion frequency, and subjective visual fatigue in Taiko no Tatsujin game playing. Four groups divided by age (young adult, adult, middle‐aged adult, and senior citizen), two types of interface (solid and touch), and two types of key areas (approximately 1.1 and 0.6 cm2) were investigated in the experiment. The results showed significant differences for age group on accuracy, especially for young adults and senior citizens. The solid interface demonstrated better accuracy and usability and less subjective visual fatigue than the touch interface. The approximately 1.1 cm2 key indicated better performance than the 0.6 cm2 key in all indexes. It is inferred that the solid interface with the 1.1 cm2 key had better performance. Therefore, mobile phones with a larger key area are more suitable for game playing.

“…Studies have also shown that reading performances of users at different ages vary when reading tasks are performed on various mobile devices, such as handheld computers [18], PDAs [19], and devices with electronic paper displays [5]. As we have expected, most of above studies conclude that young people have better reading performance than elder ones.…”

“…With the rapid advances of display technology, electronic paper has possessed more characteristics of conventional paper, such as the ability to roll or bend, that can enhance reading comfort and experience [3]. Past studies have also investigated the reading performance of electronic paper displays and indicated that surface treatment and bending curvature bring the significant impacts in participants' reading performance [4][5][6][7].…”

This study investigated the effects of display type, student population, and environment on search time, accuracy, workload, change of critical fusion frequency (CFF), and subjective visual fatigue while performing a reading task. Twenty students participated in the experiment, where three types of display (liquid crystal display, electronic paper display, and plain paper), two student populations (junior high school students and college students), and two types of environment (a controlled laboratory and a carriage of a public transit system) were investigated. The results showed that the student populations were significantly different in terms of search time, accuracy, and subjective visual fatigue. The results also showed that the interaction between display type and student population was significant on workload. The reading performance of accuracy for participants in the laboratory was significantly better than that in the public transit system.
