Exploring the use of meaningful VR experiences for those living with dementia

This thesis explores the potential of immersive technology as a tool for people living with dementia, focusing on designing and optimising immersive experiences to align with their unique needs and preferences. The research is structured around three interrelated studies, each exploring different insights into immersive interventions for dementia care. The first study investigates the feasibility and usability of a VR prototype application for dementia care through the development and evaluation of a VR video player application. This application enables individuals living with dementia to watch VR videos tailored to their interests and cognitive abilities. The study reveals both the potential of VR to enhance engagement and relaxation and the challenges posed by communication difficulties to understand the preferences of the participants. Building on these findings, the second study adopts a participatory forward-thinking approach, allowing people living with dementia to create physical model boxes comprising of items and environments that are meaningful to them. These physical models are then transformed into personalised digital VR environments. This study highlights the creative potential of people living with dementia and the importance of co-design in building emotional connection and meaningful engagement, while also identifying continued barriers in verbal communication. The third study pivots to the development of innovative design directions for immersive interventions. These directions are informed by findings from the first two studies and are structured around key features such as memory recall, physical interaction and creative expression. This study proposes concepts for immersive experiences that address the unique challenges faced by those living with dementia. Each design aims to provide opportunities for meaningful and recreational engagement. Together, these studies present a comprehensive investigation into the design, evaluation, and innovation of immersive technologies for people living with dementia. The findings inform practical recommendations for creating immersive experiences that are engaging, accessible, and personalised, with significant implications for enhancing quality of life in dementia care.
