Adaptation of workplaces and homes for disabled people using computer-aided design

Abstract

A computer-based tool has been developed to support the planning of adaptations for the physically disabled. The prototype development and evaluation were based on six case-studies, which also provided information on the needs and requirements in real-life planning situations. The tool was found useful in supporting an iterative planning process, where it is important to encourage and activate not only the disabled person, but also other people involved or affected. It was positively evaluated by the participants through its ability to enhance the understanding and encourage active participation. The tool was also found useful in supporting the planner's (e.g. an occupational therapist's) design and evaluation of aspects such as accessibility, clearance and reach, taking into consideration an individual's size and abilities. The present prototype's effectiveness was not satisfactory as modelling was relatively time-consuming. Besides rationalising the 3-D modelling, future development should also include an improved measurement control, collision detection and a simplified control of view-angles and objects. Relevance to industry Improving the planning process for workplace/home adaptations may result in more successful rehabilitation of physically disabled people.
