Exploring adaptive invitation design: an in situ longitudinal study using a smarter music player for people with dementia

People with dementia can benefit from listening to music in their daily lives, but may have limited access to music due to difficulties in product use and loss of initiative. Addressing these challenges is therefore critical in design for people with dementia. Previous work introduced inviting as a design principle to address the loss of initiative and demonstrated how it can be applied in the design of a music player for people with dementia. This paper explores how adaptive invitation design can better meet the needs of people with dementia in their daily lives. We discuss how we explored the design of adaptive invitations in an in-situ longitudinal study that included people with dementia and their caregivers, using high-fidelity prototypes of a music player. Our main insights relate to the timing of invitations, the possible need for personalised spoken instructions, and to how the product should autonomously behave.
