The materials presented in this resources were focused on human-scale Assistive Technology products and designs that were either hand-held or body worn, which included wheelchair accessories. The viewpoint taken in all studies was from that of an Industrial Designer. The context of the evaluation was from within the support and funding structures of United Kingdom (UK) based healthcare. Reference to other International healthcare structures and viewpoints were translated into or compared with a UK context. The context and terminology from definitions related to a Design discipline were from a UK perspective.

The design of medical products, such as those used in secondary care (Medical Hospitals) for example; interior design or architectural issues, such as accessibility and space design, are currently beyond the scope of this resource. Similarly, issues of creativity, design decision-making and innovation are not addressed in the resource, as outside the scope of material.

The material assumes some background knowledge of design or engineering processes. Statistical validation of outcomes are mentioned, but not discussed in detail across all the material.


There are a series of research methods, design methods and design heuristics that are grouped into phases of a design process. The process is based on United Kingdom standards and a consensus of conventions. The grouping of methods and heuristics has been made based on the experience of working in the field of assistive technology design for the last 30 years.
