Personas and usability testing
Designing a home assistant for older adults
Designing usability tests for a home assistant with voice and visual interfaces.
Design question
How could we evaluate whether an LLM-powered home assistant supports older adults with everyday tasks, including people with varying voice or visual abilities?
Approach
We developed user personas and designed usability tests for voice and visual interactions. The evaluation covered task completion, how often people had to repeat themselves, and whether they could use the device under conditions of voice or visual impairment.
Outcome
The project report earned first place at Student Career and Professional Day during the 68th Human Factors and Ergonomics Society Annual Meeting (ASPIRE).
