Customization process applied to the design of assistive devices

There has been a considerable amount of research on assistive device design, yet there is a lack of investigation concerning the design process. Existing assistive device design is mainly focused on customization design, with research and design commonly undertaken with a focus on case studies, yet the burden of assistive device customized design faced by the economically disadvantaged and disabled is even greater. This research is based mainly on the USERfit assistive device design process. It introduces the concept of tailored customization into the assistive device design process and adds expert evaluation, resulting in a new assistive device design process - The Tailored Customization Assistive Device Design Process, TCADDP. This research continues by using assistive drawings as examples, channeling the TCADDP into the assistive drawing devices for children with Cerebral Palsy, and through expert evaluation and revision, proves that assistive drawing device can improve other drawing situations faced by the physically disabled, and verifies that the TCADDP can simultaneously satisfy the usage and economic demands of the disabled in assistive device design, and help a greater number of people with disabilities.
