CareHub: Smart Screen VUI and Home Appliances Control for Older Adults
Ningjing Sun · 2020
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.
