Natural Expression of a Machine Learning Model's Uncertainty Through Verbal and Non-Verbal Behavior of Intelligent Virtual Agents
UIST '24: Proceedings of the 37th Annual ACM Symposium on User Interface Software and TechnologyArticle No.: 130, Pages 1–15https://doi.org/10.1145/3654777.3676454Uncertainty cues are inherent in natural human interaction, as they signal to communication partners how much they can rely on conveyed information. Humans subconsciously provide such signals both verbally (e.g., through expressions such as “maybe’’ or “...
