Interactive-Wear: An Intelligent Watch Application to Aid Memory for Intentions and Everyday Functioning in Older Adults with Cognitive Impairments

In this technical paper, we review an innovative speech-to-text wearable watch application (app) called Interactive-Wear (I-Wear) designed to improve memory for intended actions of individuals with Alzheimer's disease (AD). I-Wear transcribes speech spoken into the wearable app to text displayed on a web-based platform, Interactive-Care, designed to improve everyday functioning of individuals with AD and their caregivers. Regarding performance metrics, we achieved a low word error rate of 2% (98% accuracy) and a fast execution time (M=1.5 seconds). The user interface was evaluated by AD experts who rated it as highly accessible and intuitive. They also reported high ease of use and potential benefit for both individuals with cognitive impairment and their caregivers. Next, we will deploy the I-Wear to AD participants and will utilize multi-modal sensing (I-Wear + unobtrusive sensors) and artificial intelligence models to improve our understanding of cognitive and functional trajectories, detection of cognitive and health changes, and just-in-time interventions to enhance independence.
