Explore a comprehensive lecture on modeling common ground for multimodal communication presented by James Pustejovsky from Brandeis University. Delve into the evolving landscape of human-computer interactions, focusing on cooperation in shared workspaces to achieve common goals. Examine a prototype system where people and avatars collaborate to build block world structures through language, gesture, vision, and action. Learn about the VoxML modeling language, which encodes objects with rich semantic typing and action affordances, enabling contextually salient inferences in a 3D simulation environment. Discover how this platform facilitates the study of computational issues in multimodal communication and the establishment of common ground in discourse. Gain insights from a walk-through of multimodal communication in a shared task, illustrating the practical applications of this research.
