We have developed a system that can remove hand blurring by means of the moving average in the case of computer input for disabled with difficulty in motion function. It is a painting tool so that it can be used as a tool of occupational therapy, for example for cerebral palsy. Conventional mouse, pen tablet and track balls can be selected for input device depending on the patients choice.Evaluation of this tool has been carried out at Eastern Shimane Rehabilitation Center for Disabled. The experiment method is tracing sample templates and the blurring is quantitatively measured. The mean root square of blurring after blurring compensation is compared with normal drawing and the error is smaller for the compensated tracing. However, t-test cannot detect the difference between them. It may be, attributed to large personal errors that depend on the degree of their disabilities. We shall improve the experimental procedure so that the degree of disability reflects the averaging level autom … More atically, and it is still open to deal with.For those who are not able to handle mouse device, we have made a mechanical device that is based on the drafting table. However the size of the table is too large to handle the mouse and is not used in real operation. We propose an alternative device that can be used by heavily disabled patient by using of a so-called handy game player, supplied by several vendors. The reason why the game player is a candidate is that it has enough stiffness both in body and switches and the number of operation switches is appropriate to do simple operation. We are developing this device still now.We have also developed software keyboard in addition to drawing tool. This keyboard is also for the people who have involuntary movement in action, and the special function of cursor trapping and key enlarging. This tool will be tested in near future at Hyogo Prefecture General Rehabilitation Center for occupational therapy. Our point in this keyboard is that it adopt a key layout of mobile phone input method. This layout is effective when the mouse movement is carried out with difficulty. Less

我们开发了一个系统，可以消除手模糊的移动平均的方式在计算机输入的情况下，对残疾人的运动功能有困难的。它是一种绘画工具，因此可以用作职业治疗的工具，例如脑瘫。根据患者的选择，可以选择传统的鼠标、手写板和轨迹球作为输入设备。在东岛根残疾人康复中心对该工具进行了评估。实验方法是跟踪样本模板，并对模糊进行定量测量。将模糊补偿后的模糊均方根值与正常绘图进行了比较，补偿后的跟踪误差较小。然而，t检验不能检测它们之间的差异。这可能是，归因于大的个人错误，这取决于他们的残疾程度.我们将改进实验程序，使残疾程度反映平均水平， ...更多信息 对于那些无法处理鼠标设备的人，我们已经做出了一个基于绘图台的机械设备。然而，表的大小太大，无法处理鼠标，并且不用于真实的操作。我们提出了一种替代设备，可用于重度残疾患者使用的所谓的方便的游戏机，由几个供应商提供。游戏机是候选者的原因是它在主体和开关上都具有足够的刚度，并且操作开关的数量适合于进行简单的操作。我们现在还在开发这个设备。除了绘图工具，我们还开发了软件键盘。此键盘也适用于行动中有不自主运动的人，并具有光标捕获和键放大的特殊功能。这一工具将在不久的将来在兵库县综合康复中心进行职业治疗试验。我们在这个键盘上的观点是，它采用了移动的手机输入法的按键布局。当鼠标移动困难时，这种布局是有效的。少
