CAD Models as a Co-Design Tool for Older Users: A Pilot Study

Abstract

The UK population is ageing, and currently, the design needs of older adults are not being met. Increased older user participation is required in design. It is proposed that CAD (Computer Aided Design) and Rapid Prototyping (RP) models can be used as a tool to facilitate user involvement early in the design process. This paper explores the potential for a computer-aided participatory -design process for older adults. It questions older users' understanding of CAD models of products in terms of 'physical product properties' such as perceived size, weight, colour, surface properties and 'subjective attributes' such as perceived quality. It aims to establish how far older adults are able to understand CAD models shown on a computer screen. This work-in-progress paper discusses the current literature in relation to ageing and CAD, and goes on to describe the methodology for a pilot study, which forms part of the first stage of PhD research.
