Abstract
An experimental simulation of a VDT data entry task was conducted during which subjects alternated between good and poor ergonomic conditions involving postural adjustment, lighting, and glare. Performance measures were taken during the session and a battery of psychophysical/physiological measures and subjective complaints were taken before and after the work session. Preliminary results indicated a 24.5% improvement in performance as well as a decrease in musculoskeletal complaints attributed to good ergonomic design characteristics.
