The study of Relationship between Mental Work Load and Sleep Quality in Video Display Terminals Users
Background & objectives: One of the factors affecting the performance of video display terminal users is their mental work load. Since low sleep quality causes fault and decreased accuracy in work, this study aimed to evaluate the relationship between mental work load and sleep quality in video display terminals users. Methods: This descriptive cross-sectional study was performed on 191 video d...
متن کاملWork related and individual predictors for incident neck pain among office employees working with video display units.
AIMS To investigate work related and individual factors as predictors for incident neck pain among office employees working with video display units (VDUs). METHODS Employees in three administrative units of a medium sized city in Finland (n = 515) received mailed questionnaires in the baseline survey in 1998 and in the follow up survey in 1999. Response rate for the baseline was 81% (n = 416...
متن کاملA binocular stereoscopic display system with coupled convergence and accommodation demands
Conflict between the accommodation and convergence demand in stereo display systems has been implicated as a cause for perceptual error (failure of size constancy), discomfort and visual system changes. A novel method is proposed for such displays, which, by utilizing measured object of fixation can resolve the conflicts via computational approach. We implemented such a display system and used ...

متن کاملDisparity-driven vs blur-driven models of accommodation and convergence in binocular vision and intermittent strabismus
PURPOSE To propose an alternative and practical model to conceptualize clinical patterns of concomitant intermittent strabismus, heterophoria, and convergence and accommodation anomalies. METHODS Despite identical ratios, there can be a disparity- or blur-biased "style" in three hypothetical scenarios: normal; high ratio of accommodative convergence to accommodation (AC/A) and low ratio of co...
