• Controlling Social Dynamics with a Parametrized Model of Floor Regulation 

      Chao, Crystal; Thomaz, Andrea L. (Georgia Institute of TechnologyBrigham Young University, 2012)
      Turn-taking is ubiquitous in human communication, yet turn-taking between humans and robots continues to be stilted and awkward for human users. The goal of our work is to build autonomous robot controllers for successfully ...
    • Designing Interactions for Robot Active Learners 

      Cakmak, Maya; Chao, Crystal; Thomaz, Andrea L. (Georgia Institute of TechnologyInstitute of Electrical & Electronics Engineers, 2010-06)
      This paper addresses some of the problems that arise when applying active learning to the context of human–robot interaction (HRI). Active learning is an attractive strategy for robot learners because it has the potential ...
    • Keyframe-based Learning from Demonstration Method and Evaluation 

      Akgun, Baris; Cakmak, Maya; Jiang, Karl; Thomaz, Andrea L. (Georgia Institute of TechnologySpringer, 2012-06)
      We present a framework for learning skills from novel types of demonstrations that have been shown to be desirable from a human-robot interaction perspective. Our approach –Keyframe-based Learning from Demonstration (KLfD)– ...
    • Multimodal Real-Time Contingency Detection for HRI 

      Chu, Vivian; Bullard, Kalesha; Thomaz, Andrea L. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2014-09)
      Our goal is to develop robots that naturally engage people in social exchanges. In this paper, we focus on the problem of recognizing that a person is responsive to a robot’s request for interaction. Inspired by human ...
    • Timing in Multimodal Turn-Taking Interactions: Control and Analysis Using Timed Petri Nets 

      Chao, Crystal; Thomaz, Andrea L. (Georgia Institute of TechnologyBrigham Young University, 2012)
      Turn-taking interactions with humans are multimodal and reciprocal in nature. In addition, the timing of actions is of great importance, as it influences both social and task strategies. To enable the precise control and ...
    • Transparent Active Learning for Robots 

      Chao, Crystal; Cakmak, Maya; Thomaz, Andrea L. (Georgia Institute of TechnologyInstitute of Electrical & Electronics Engineers, 2010)
      This research aims to enable robots to learn from human teachers. Motivated by human social learning, we believe that a transparent learning process can help guide the human teacher to provide the most informative ...
    • Vision-based Contingency Detection 

      Lee, Jinhan; Kiser, Jeffrey F.; Bobick, Aaron F.; Thomaz, Andrea L. (Georgia Institute of TechnologyAssociation for Computing Machinery, 2011)
      We present a novel method for the visual detection of a contingent response by a human to the stimulus of a robot action. Contingency is de ned as a change in an agent's be- havior within a speci c time window in direct ...
