An experimental simulation of a VDT entry task was conducted during five three-hour test sessions in which subjects worked under ergonomic conditions alternating between good and poor features as defined by adjustments of working and seating surfaces, lighting, and glare. Performance measures were taken during each session and a battery of psychophysical/physiological measures and subjective complaints were taken before and after each 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.
