电脑被认为是身体和认知康复的一个非常有用的工具。然而，由于运动疾病，残疾人在正确控制传统用户界面方面存在局限性。本文是在一个项目的框架，以创建一个替代的计算机接口，特别是针对脑瘫儿童（CP）。接口是一个基于惯性技术的头鼠标。尽管对于健康用户来说，惯性界面可以作为鼠标指针使用，但患有CP的儿童有不自主的运动，如痉挛或震颤，这限制了控制。本文采用惯性界面对3例小儿CP（高张力-动脉样位、高张力-肌张力障碍和低张力-动脉样位）的病理模式进行运动学参数分析和病理运动谱分析。最后，设计并评估了两种过滤技术，以减少非随意运动的影响，提高界面作为鼠标指针的可访问性。
The computer is considered a very useful tool for physical and cognitive rehabilitation. However, people with disabilities have limitations to control properly conventional user interfaces because of their motor diseases. This paper is in the framework of a project to create an alternative computer interface, especially addressed to children with Cerebral Palsy (CP). The interface is a head mouse based on inertial technology. Although the inertial interface succeeds as mouse pointer for healthy users, children with CP have involuntary movements, such as spasms or tremor, which limit the control. In this paper, the inertial interface is used to analyze the pathological patterns of three children with CP (hypertonic-athetoid, hypertonic-dystonic and hypotonic-athetoid cases) in terms of kinematic parameters and spectral analysis of the pathological motion. Finally, two filtering techniques are designed and evaluated to reduce the effects of the involuntary motion and improve the accessibility of the interface as mouse pointer.
