Developing virtual environments for older users: Case studies of virtual environments iteratively developed for older users and people with dementia

This paper describes two case studies of virtual environment systems designed for older people. In particular, the paper outlines the process and technology used to develop the virtual environments as well as the lessons learnt from the iterative design process. The first case study describes two multi-user virtual environments that were designed as a social interaction platform for older people staying at home. This system was conceptualized through an initial focus group session and was refined through iterative testing. The second case study describes a virtual environment system that was developed for a care home setting to encourage interaction between People with Dementia and their care givers. To better facilitate engagement for such users, the system made use of tangible user interfaces through physical artifacts embedded with NFC tags.
