Abstract:
Objective To study the characteristics of pointing movement time for targets with different position in front of human body,to detect the effects of targets location on pointing movement time.Methods A pointing movement experiment of human arm was designed and carried out.By the statistic analysis of the experimental data,the relationship between pointing movement time and target position was discussed.Results It was shown that the starting point position and target position extremely affected the pointing movement time.Conclusion When a right-handed person touches the different targets,both the direction to target and the starting point position(target-circle location) would affect the pointing movement time extremely.When the position of the starting point changed by horizontal or vertical,the pointing movement time is more changeful by horizontal than that by vertical.To compare the pointing movement time for each target on a target-circle,the pointing movement time for right-upper target is the shortest.When the starting point is located on the right side of human body,all pointing movement time of that target-circle is the shortest.
