Many people with multiple impairments need to use a powered wheelchair, voice output communication aid, environmental control, and access information technology. Integrating and mounting such assistive devices on a powered wheelchair can be time-consuming, expensive and result in compromised performance. This paper offers a concept of assistive device integration, based around a continuum ranging from wholly discrete systems to fully integrated systems. Using practical examples, advantages and disadvantages of different approaches to integration along this continuum are identified, particularly with regard to control characteristics of different types of assistive technology. Limitations of current practices and technologies are discussed and measures suggested to enable systems to achieve better integration.
许多有多种损伤的人需要使用电动轮椅、语音输出通讯辅助设备、环境控制系统和信息技术设备。将这些辅助设备集成并安装到电动轮椅上可能既耗时又昂贵，而且会导致性能受损。本文提出了一种辅助设备集成的概念，该概念基于从完全离散系统到完全集成系统的连续统一体。通过实际例子，确定了沿此连续统一体不同集成方法的优缺点，特别是关于不同类型辅助技术的控制特性。讨论了当前实践和技术的局限性，并提出了使系统实现更好集成的措施。
