With the number of people living with dementia expected to significantly rise over the coming years, development of assistive technologies is more important than ever. Integrating AI into these may help address the changing needs of older adults living with dementia (OALWD). However, in order to better recognize and serve those needs, a firm grounding in disability justice (DJ) is necessary in the research, development, and dissemination of assistive technologies. The objective of this paper is to evaluate emerging assistive technologies featuring AI for dementia based on disability justice principles and Nancy Fraser’s three-dimensional framework for social justice, adapting and applying Fraser’s framework as a means of working towards the principles wherever appropriate with the aim of identifying gaps for further research. Tools from four primary areas of relevant technological development for dementia are selected and evaluated, and the possibilities of these tools perpetuating existing injustices is explored.
