Abstract: Even though manual tracking performance has been extensively investigated, there is little or no research related to the lower limit of temperature for unimpaired tracking performance. This study sought to obtain temperature limits while investigating the effect of hand-skin temperature on manual tracking. Eighteen subjects participated in a within-subject design experiment. The hand-skin temperatures corresponded to bath temperatures of 10, 20 and 30℃. Tracking performance was measured using the Drury (1971) task of drawing between two continuous straight lines of length 200mm and widths 1.5 mm, 2mm, 2.5mm, 3mm, and 4mm. Performance measures were the time to draw the line and the number of errors as determined by the cross-over points of the drawn line with the printed lines. Both performance measures were consistent and showed significant effects (p< 0.05) of line spacing and hand-skin temperature. Performance with bath temperatures of 10℃ was significantly worse than that with bath temperatures of 20℃ and 30℃.
