摘要
目的研究人体的目标拾取运动特征 ,解决人体的目标拾取运动的时间计算问题。方法通过对前人实验数据的可视化分析 ,验证了所提出的假设模型的正确性。结果针对人体的目标拾取运动特征的研究 ,提出截止目标尺度的概念 ,推导出人体的目标拾取运动的时间计算方程。结论实验数据表明 ,该计算方程对人的目标拾取运动能够给予较好的描述 ,能够准确有效地计算出人的目标拾取运动的时间 ,优于传统的计算方法 。
Objective This paper deals with the problem of human movement characteristics of target acquisition. Method A hypothetical model was posed by using experimental data. Result The conception of final target size was put forward, an equation for calculating the movement time of target acquisition was obtained, and a new definition of index of difficulty was given. Conclusion Analysis of experimental data showed that this equation could give a better description of target acquisition in a wide range.
