“…Numerous studies have found that prolonged work at visual display terminals (VDTs) can impact negatively on employee health, in terms of musculoskeletal problems, visual discomfort and other eye problems, general fatigue, and psychological stress (e.g. Aaras, Horgen, & Ro, 2000;Dillon & Emurian, 1996;Ekberg et al, 1995). More research is required to investigate the long-term health eVects of VDTs.…”

Over the last 40 years, major changes have taken place in the workplace. The growth in the use of information technology at work, the globalization of many industries, organizational restructuring, changes in work contracts and worktime scheduling have radically transformed the nature of work in many organizations. The workforce itself is also diversifying, with an increase in female participation, a growing number of dual‐earner couples and older workers. The present paper discusses the impact of these workplace transitions on employee well‐being. We focus on four issues that are current concerns for organizations and the workforce; job insecurity, work hours, control at work, and managerial style. For each topic, recent research is presented, with suggestions for future research and recommendations for practitioners working in the organizations of today. The paper concludes with some final considerations for researchers and practitioners that may benefit both employee well‐being and organizational effectiveness.

“…There has been previous research on the investigation of the users' comprehension of displays used in the past decade, such as cathode-ray tubes (CRTs) and transmissive liquid-crystal displays (LCDs). [1][2][3][4][5] Reflectivetype displays are new electronic displays that use an ambient light source, which differs markedly from that of conventional CRTs and transmissive-type LCDs which self-emit or transmit light. Consequently, the design guidelines for CRTs and transmissive LCDs can not be applied to reflective displays.…”

Abstract— This study used several electronic‐book (e‐book) displays (a conventional LCD under transmissive mode, a conventional LCD under reflective mode, a Ch‐LC display, and an e‐ink display) to investigate the effect of e‐book inclination (105° and 135°) and ambient illuminance (200, 800, 1500, and 2200 lux) on the comprehension of subjects. Results indicate that the ambient illuminance does not significantly affect the comprehension of subjects. However, their comprehension differed significantly when using different e‐book displays. In addition, the interaction between illuminance and e‐book display had a significant effect on their comprehension. When the ambient illuminance was set at 800, 1500, and 2200 lux, the subjects' comprehension for reading different e‐book displays did not show a significant difference. When the ambient illuminance was set at 200 lux, however, their comprehension for reading a Ch‐LC display, an e‐ink display, and a conventional LCD under transmissive mode were better than their comprehension of reading a conventional LCD under reflective mode. Regarding the inclination for using e‐books, the subjects' comprehension was better under 105° than that under 135°.

“…Beginning with the visual display terminal (VDT), investigations of the influence of difference displays on health have had a long history. [27][28][29][30] Among them, the SSQ proposed by Kennedy et al is used in many psychophysics studies, since the questionnaire for an actual symptom is related to fatigue and discomfort factors. 31,32 Table 1 shows the questionnaire items in the SSQ and the corresponding psychophysics factors.…”

Abstract— In this paper, the relative influences of misalignment such as cross‐talk, vertical shift, and motion blur on visual fatigue by using a binocular stereoscopic display has been verified. Experiments were conducted for two cases: a still image and a motion image. They were evaluated by using the simulator sickness questionnaire (SSQ). By changing the disparity angle, cross‐talk, and vertical shift in the still‐image experiment, it was found that the SSQ score of each parameter increased as the amount of each factor increased. With a two‐sample t‐test between the presence and absence of each factor, a significant difference was found for the case of a more than 36‐arcmin disparity, more than 20% cross‐talk, and more than 10% vertical shift. In the motion‐image experiment, in which motion speed and the misalignment were varied, it was found that movement of the disparity angle caused much more visual fatigue in comparison with the misalignment factors, which were cross‐talk and vertical shift. In contrast, motion images in addition to the cross‐talk and/or vertical shift had a slight but unnoticeable relationship to an increase in visual fatigue. Therefore, it was concluded that vertical shift dominated the evaluation for still images, and the movement itself dominated the evaluation for motion images. The results suggest that it is necessary to evaluate visual fatigue according to the representing case, still or motion images, of a 3‐D stereoscopic display.
