Abstract
The purpose of this study was to investigate the differences in performance and muscle effort between guideline and preferred setting of keyboard and mouse when using a computer in supine posture. The guideline setting is according to the rules of standard sitting posture; and the preferred setting is freely determined by the subjects. Ten healthy adults and ten people with disabilities of the lower extremities participated in this study. The experimental tasks included typing and mouse dragging tasks. The task performances and electromyography (EMG) were collected. The participants had significantly higher performances and lower muscle effort when using the mouse under preferred setting, as compared with the guideline setting. However, little difference in typing performance was found between the guideline and preferred settings. The results of this study are helpful to designing a supine computer workstation.
