CareHub: Smart Screen VUI and Home Appliances Control for Older Adults

Abstract

While voice user interfaces (VUIs) are becoming promising tools for users to control home appliances, the VUIs pose great challenges to the older adults. In this paper, I explored how to use multimedia interactions (i.e., voice+visual output) to enhance the VUI for older adults to better control home appliances. I conducted two preliminary studies with six older adults to understand the current usability problems. Given the results, I designed a smart screen prototype with visual-enhanced VUI. The evaluation showed that the participants were highly receptive to the prototype and considered its features effective and accessible.
