Explore a 22-minute conference talk from the ACM Symposium on Spatial User Interaction 2019 that introduces the concept of blended agents in mixed reality environments. Dive into how these agents can manipulate physical objects through robotic actuators and thermochromic ink. Learn about the study conducted to investigate the effects of virtual-physical interactions on perceived social and spatial presence. Discover the potential implications for improving realism and user experience in mixed reality scenarios. Gain insights into the challenges and future directions for integrating virtual agents with physical environments.
