Possibility of improvement of dexterity of unskilled people through the control of displayed information

在制造产品的过程中，人类从她/他的感觉中接收到一些信息来控制她/他的身体运动。本研究探讨了感官信息的变化对人在制造产品过程中的表现的影响。具体来说，调查的对象是画线任务，这是一项基础性的任务。我们要求受试者沿着显示的点线画一条线，同时改变点的空间和形状，我们调查了受试者的表现是如何变化的。结果表明，为了获得良好的表现，显示的点线应该根据受试者的技能水平而变化。我们未来（正在进行）的工作是在此研究结果的基础上开发人体灵巧控制系统。

During making products, human being receives several information from her/his sensations for controlling her/his body motions. This research investigates the effect of the change in the sensory information on human performance in making products.Concretely speaking, the target for the investigation was line drawing task that is the fundamental task. We asked subjects to draw a line along a displayed dot line while changing the space and shape of the dots, and we investigated how performance of the subjects changed. The results indicates that for good performance, the displayed dot line should change according to the skill level of the subject. Our future (on-going) work is the development of human dexterity control system based on this investigation results.
