Abstract
The purpose of this study was to show the constraints that demarcate right and left areas in designing a performance-based workstation. As a part of the larger project, the current experiment was designed to determine the directional location at which people change from using their right hand to using their left hand when reaching for a pen to write their name. The results from 21 right-handed participants showed that their left hand was not used significantly in any azimuth lines. Although right-handed participants used their left hand more often as the target location approached their contralateral side of their body, the frequencies of left hand use were not significantly dominant even beyond the left shoulder plane used in this experiment. Along with findings from previous work, we conclude that for this particular task the hand-use transition occurs beyond 20 degrees left of left shoulder plane. The location of this boundary is markedly farther to the left than identified in other research, thereby demonstrating the importance of task constraint in describing work area.
