In search of a decision-making framework for involving users who have learning disabilities or sensory impairments in the process of designing future technologies

A comprehensive literature review was undertaken in order to identify design approaches that have been employed with users who have learning disabilities or sensory impairment; the factors that influenced their choices and the extent to which the approaches and techniques adopted were successful. There was a huge variation across the corpus regarding whether a justification was offered for the choice of approach and the extent to which those justifications were supported by evidence. In addition there was a lack of comprehensive evaluation of the design approaches. Technology designers who intend working with users with learning disabilities or sensory impairments therefore currently have little to help them decide which design approach might be the most appropriate or effective
