What if voice interfaces were designed using conceptual metaphors?

Traditionally, voice interfaces are designed based on a ‘humanness’ metaphor—to act like an assistant, a teacher, or even a grandma. But is this a good idea? Spoiler: It’s not. In this project, we explain why this simplistic role reproduction is a bad idea and how we can design better voice interfaces using conceptual metaphors.

How do older and younger adults learn health information with voice interfaces?

In this study, we investigate the feasibility of delivering health information with voice interfaces to younger and older adults. We designed a voice interface, “Health Buddy,” capable of implementing self-regulated learning and metacognition strategies.

Can older adults learn health information with a murder mystery story told by a smart speaker?

We designed “Mystery Agent,” a storytelling voice assistant teaching health information to older adults using an interactive murder mystery story.

Can older adults use voice interfaces to exercise?

We built a voice agent capable of acting as an exercise instructor to support older adults seeking to live an active life.
