  Conference Proceeding: Action parsing and goal inference using self as simulator

  [show abstract] [hide abstract]
  ABSTRACT: The ability to understand a teammate's actions in terms of goals and other mental states is an important element of cooperative behavior. Simulation theory argues in favor of an embodied approach whereby humans reuse parts of their cognitive structure for not only generating behavior, but also for simulating the mental states responsible for generating that behavior in others. We present our simulation-theoretic approach and demonstrates its performance in a collaborative task scenario. The robot offers its human teammate assistance by either inferring the human's belief states to anticipate their informational needs, or inferring the human's goal states to physically help the human achieve those goals.

  Conference Proceeding: Working collaboratively with humanoid robots

  ABSTRACT: This paper presents an overview of our work towards building humanoid robots that can work alongside people as cooperative teammates. We present our theoretical framework based on a novel combination of joint intention theory and collaborative discourse theory, and demonstrate how it can be applied to allow a human to work cooperatively with a humanoid robot on a joint task using speech, gesture, and expressive cues. Such issues must be addressed to enable many new and exciting applications for humanoid robots that require them to assist ordinary people in daily activities or to work as capable members of human-robot teams.

  Conference Proceeding: Social robots: beyond tools to partners

  C. Breazeal, J. Gray, G. Hoffman, M. Berlin
  [show abstract] [hide abstract]
  ABSTRACT: This work presents our efforts towards building sociable autonomous robots that can work in collaboration with people. In teamwork, it is critical that a robot partner be able to infer and understand the human's goals and intentions in order to anticipate the person's needs and offer appropriate assistance in a timely manner. We present our framework for human-robot collaboration based on joint intention theory, and our initial efforts to develop a simulation-theoretic approach for anticipating the human partner's goals to proactively offer help. These abilities would enable many new and exciting applications for robots that require them to play a long-term, supportive, and helpful role in people's daily lives.

  Conference Proceeding: Interactive robot theatre

  C. Breazeal, A. Brooks, J. Gray, M. Hancher, C. Kidd, J. McBean, D. Stiehl, J. Strickon
  [show abstract] [hide abstract]
  ABSTRACT: This work motivates interactive robot theatre as an interesting test bed to explore research issues in the development of sociable robots and to investigate the relationship between autonomous robots and intelligent environments. We present the implementation of our initial exploration in this area highlighting three core technologies. First, an integrated show control software development platform for the design and control of an intelligent stage. Second, a stereo vision system that tracks multiple features on multiple audience participants in real-time. Third, an interactive, autonomous robot performer with natural and expressive movement that combines techniques from character animation and robot control.
