人体前方平面上目标点拾取运动特性及工效研究

目的 研究人体上肢对前方平面不同区域目标点的拾取运动特性和工效.方法 设计并进行了目标拾取实验,得到了人体上肢拾取前方平面上目标点所需时间、速度、运动轨迹线长度、功率等实验数据.结果 通过实验分析,初步揭示了不同区域目标点的拾取运动特性存在较大的差异.结论 右利手者拾取前方平面上目标点时,左上区目标点的拾取运动工效最好,右下区目标点的拾取运动工效最差.

A Study of Pointing Movement Characteristics and Ergonomics on Front Board

Objective To study pointing movement characteristics and ergonomics when human upper limb touches different targets on the front board. Methods An experiment was designed, in which the data of motion duration, peak velocity, trajectory length and peak power at shoulder and elbow joint were collected. Results By analysis of the experimental results, the pointing movement characteristics among the different regions on the front board were disclosed preliminarily. Conclusion When a right-handed person touches a target on the front board, the pointing movement ergonomics on left-upper region is the best, while that on right-lower region is the worst.
