Deveolopment of Computer Input Interface using Pen Tablets for Disabled with Unvoluntary Motion

我们已经开发出一种系统，可以在运动功能困难的残疾人的计算机输入情况下，利用移动平均来消除手部模糊。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，可以选择常规的鼠标、笔式书写板和轨迹球作为输入设备。该工具已在东部岛根残疾人康复中心进行了评估。实验方法是示踪样本模板，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-检验不能检测出它们之间的差异。它可能是，归因于巨大的个人错误，这取决于他们的残疾程度。我们将改进实验程序，使残疾程度反映自动…的平均水平对于那些不能操作鼠标设备的人，我们制作了一种基于绘图台的机械设备。然而，桌子太大，无法处理鼠标，不能在实际操作中使用。我们提出了一种可供重度残疾患者使用的替代设备，它使用的是几家供应商提供的所谓的轻便游戏播放器。游戏玩家之所以是候选者，是因为它在机身和开关上都有足够的刚度，操作开关的数量适合做简单的操作。我们现在还在开发这个设备，除了绘图工具之外，我们还开发了软件键盘。这款键盘也是为行动中有不自主运动的人而设计的，并具有特殊的光标捕捉和按键放大功能。这一工具将在不久的将来在兵库县综合康复中心进行作业治疗测试。我们在这款键盘上的要点是，它采用了手机输入法的按键布局。当难以执行鼠标移动时，该布局有效。较少

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
