ALT Journal cover for Integrative and Comparative Biology, a journal of the Society for Integrative and Comparative Biology. Cover features a snake with large fangs exposed, and three smaller illustrations of fangs puncturing into layers of tissue.

ALT The bite-bot robo-physical model. The model has a swing arm with a fang at its end, which sits above a small piece of equipment that holds a sponge. The model's height is adjustable. Image text: "Bite-Bot can independently vary: Venom pressure, pressure duration, venom viscosity, fang size, fang angle, fang shape, fang canaliculation state, bite force, bite speed."

ALT Robots are increasingly integrated into everyday contexts, including museums, where they can both entertain and educate visitors. To enhance visitor experience and engagement, we present a novel mixed-agent tour guide system that combines a physical robot with a projected virtual agent that actively participates in the tour through conversation and interaction, achieving the interaction richness of two mobile agents from a single platform. We validate the system through a within-subjects study with 30 participants to assess engagement, quality of experience, and learning performance. Participants experienced different conversational styles and agent configurations, and data were collected via surveys, behavioral sensors, and interviews. Results showed that engagement and quality of experience remained consistent across conditions. Learning performance revealed a significant gender-moderated difference: the mixed-agent conditions improved learning performance for female participants. Th
