Intelligent assistive technology devices for persons with dementia : a scoping review

Abstract

Assistive technology with context-aware computing and artificial intelligence capabilities can be applied to address cognitive and communication impairments experienced by persons with dementia (PwD). This research aims to provide an overview of current literature regarding characteristics of intelligent assistive technology devices (IATDs) for cognitive and communicative impairments of PwD as well as of the areas of impairment addressed by the IATDS. A multi-faceted systematic search strategy involving three electronic database platforms, two electronic databases and three electronic journals yielded records produced over the past decade. Predefined criteria were applied for inclusion and data extraction. Data was thematically analysed and synthesised. This review demonstrates that the bulk of research involving IATDs over the past decade has focused on cognitive impairments of PwD and has not yet evolved past the conceptual or prototype stages of development. A summary of commercially available IATDs for PwD is provided at the end of this review. This research concluded that IATDs for PwD primarily focus on social robots, especially PARO, and that they address cognitive impairments of attention and affect, as well as social-pragmatic communicative impairments. Few IATDs address the linguistic impairments experienced by PwD. Future research should involve collaboration between computer engineering and health practitioners to address the identified gaps and to contribute to evidence-based decision making for PwD.
