Technological supports have the potential to greatly improve the quality of life and independence of adults with severe speech and physical impairments (SSPI). In particular, augmentative and alternative communication (AAC) devices can enable people with little or no speech to communicate with others. However, the rate of rejection of AAC devices is estimated to be as high as 53.3%. It is suggested that a major reason for this rejection is a lack of user-centred design in the development of these devices. As part of a wider study looking at involving adults with SSPI in all stages of user-centred design, this paper looks at the use of focus groups in requirements gathering with this user group.
