Study to reveal what makes a virtual assistant trustworthy
NCT ID NCT07666295
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the design and performance of virtual assistants—like chatbots or avatars—affect how people feel about them. About 400 adults will interact with these assistants in simulated service situations, such as tourism or retail. Afterward, they will answer questions about trust, satisfaction, and whether they would use the assistant again. The goal is to better understand human interaction with AI, not to test any medical treatment.
