Investigation about user interface to be tender for a disabled person and device development

本研究采用调查研究与案例研究相结合的方法。掌握一名以脑损伤为主的残疾人使用信息设备的现状，分析长期使用设备对身心健康的影响。案例研究与视频分析我对一个长期使用的信息装置进行了试用测试，大约有5名残疾人，他们都有不同种类和程度的损伤。(2)问卷调查我分析了预搜索的答案，然后进行了广泛的调查。我发出了638封调查问卷。收集率为34.0%。被访者使用的信息设备是个人电脑(133人)和文字处理机(129人)，其他人(224人)(一人有几个答案)。键盘是主要的输入设备。对于被认为是为了长期使用信息设备而出现的身体异常情况，58.2%的人回答“是”。出现技术应激等主观症状，主要表现为睡眠障碍。对于脑瘫患者来说，正确的问题是他们感到头痛，肩膀僵硬，肌肉或关节疼痛，在使用设备时由于持续的肌肉紧张而突出，即使一天的使用时间很短。肌张力分析与制定指南将脑瘫患者所经历的器械故障和使用不便进行归类，并结合肌张力控制的特点分析器械的使用。然后，我尝试制定与运动动作相对应的标准设备使用和设备改进指标。

I used investigation study together with case study in this research. I tried to grasp present condition about information device use of a disabled person, who principally had brain damage, and analyzed the influence for mind and body by long term use of device. Then I investigated direction of development of the input assistance device for a handicapped person.(1) Case study & video analysisI did trial test of a long term of information device, about five disabled persons, who have a various kind and degree of damage.(2) Questionnaire investigationI analyzed the answers of pre-search, and then investigate widely. I send 638 mails of questionnaire. The collection rate was 34.0 %. The information device which a respondent used was personal computer (133 persons) and word processor (129 persons), and the others (224 persons) (there are several answers with one person).

There were appeared subjective symptoms like technostress, including sleep disturbance mainly. The proper problems for cerebral palsied persons were that they feel a headache, stiffness in the shoulders and a pain of muscle or joint, stood out from continuing muscular tension in device use, even if use time for on e day was short. But there were a few persons who had subjective symptoms about motor action and posture.(3) Muscular tension analysis and making guidelinescategorized trouble of device and feeling inconvenience in use of device, which was experienced by cerebral palsied persons, and analyzed device use in concerned with characteristic of muscular tension control. Then I tried to make indicator of standard device use and device improvement corresponding to motor action.
