The End-User Engagement Committee aims to actively involve people living with dementia, carers, stakeholders and the public, to work with the research team to review and offer high level adice on the design, development, feasibility implementation, and user acquisition strategy of the MATCH application. It brings together a diverse range of voices and experiences to influence the design and process to help ensure End-Users contribute to the final MATCH mobile application that is safe and acceptable. The Engagement is carried out ‘with’ or ‘by’ members of the public rather than ‘to’, ‘about’ or ‘for’ them.
