Engagement Recognition And Generation For Human-Robot Interaction
Abstract: This talk will discuss our recent results on a computational model of engagement in human-robot interaction. Based on a study of human behavior, we have formalized the timelines for four types of "connection events:" directed gaze, mutual facial gaze, adjacency pairs and backchannels. We have implemented Robot Operating System (ROS) modules for automatically recognizing and generating these connection events between a human and a humanoid robot. Furthermore, the generation module implements policies for appropriately adding gaze and deictic gestures to referring phrases. Finally, we have validated the effectiveness of these modules with a controlled experiment.
Disco: An Open Source Tool for Dialog Management
Abstract: This talk delves into the basic capabilities of Disco, a mature, open-source tool, written in Java, for dialog interpretation and generation based on the work of Grosz, Sidner and Lochbaum. The talk will discuss the overall structure of the system, the CEA-2018 standard used for representing task recipes, and the discourse state update and generation algorithms. The talk will also describe a few recent systems that use Disco for creating agents with dialog capabilities.
