| Summary: | BackgroundPersons living with dementia and their caregivers experience frequent emotional health challenges. Across the illness spectrum, engaging in shared pleasant activities is an important feature of well-being for persons living with dementia–caregiver dyads. Under the umbrella of virtual reality, immersive virtual environment technology (IVET) offers artificial sensory experiences and shows promise in this population. IVET development benefits from a user-centered design approach, and as an emerging field, preliminary testing of safety, usability, and engagement for person living with dementia–caregiver dyads is required.
ObjectiveWe aimed to develop a preliminary IVET intervention for psychosocial health among person living with dementia–caregiver dyads. In doing so, we highlight design considerations and user preferences to ensure the safety and usability of technology-based interventions in the context of dementia.
MethodsWe engaged 10 clinicians, 8 caregivers, and 3 persons living with dementia in 5 rounds of focus groups to evaluate the safety and usability of preliminary intervention features. Following prototype development, we engaged caregivers and persons living with dementia (n=9 dyads) in beta testing workshops to observe real-time user interaction with the intervention and guide refinements. Rapid data analysis was used to extract themes relevant to intervention development.
ResultsThe following themes emerged from focus groups to inform prototype development: (1) designing flexibly to allow users to tailor the intervention experience to their own environmental context and circumstance, (2) designing with the dyad’s clinical and relational needs in mind, and (3) accounting for illness and aging-related challenges in design. The following themes emerged from workshops to inform prototype refinements: (1) increasing user support through more feedback and (2) increasing variety of visual and auditory feedback.
ConclusionsUsing user feedback throughout the development process, we developed a prototype of an IVET intervention, Toolkit for Experiential Well-Being in Dementia (the Isle of TEND), tailored to the needs of persons living with dementia and their caregivers. Our prototype uses specific design features to promote safety, usability, and engagement in the context of dementia. Future feasibility testing of the intervention is warranted.
