This paper compares the processes and methods of nine cases of assistive technology design (AT) with the predominant model of Inclusive Design (ID).There is a comparison of both process and methods. Design for AT requires a special focus on user-requirements during product development, and as such ID methodology is relevant to AT design. Research in AT design has both drawn from and added to the ID knowledge base. However, mainstream ID operates under different conditions from AT, where the scale of projects is smaller. Semi-structured interviews were carried out with nine designers of assistive technology. This provided raw data on the processes and methods used in a range of products including a children's wheelchair, a wash-basin system, a wheeled walking frame and breathing apparatus. It was found that design for AT has some overlap with design for mainstream ID, but there are important differences of emphasis, in particular: a) that user investigations must draw on stakeholders other than users (carers and medical professionals) when gathering user requirements and conducting verification testing, b) requirements gathering and definition is under-emphasised and c) prototyping becomes a more important element of the design process.
