摘要

As personal robots enter the social environments of our workplaces and homes, it will be important for them to be able to learn from a wide demographic of people. Our research seeks to identify simple, natural, and prevalent human teaching cues that are useful for directing the attention of robot learners so that robots can learn efficiently and effectively from these interactions. This research goal is significant for several reasons. First, most people do not have expertise in robotics or machine learning techniques. Second, personal robots will have to learn new tasks and skills within the bounds of human attention and patience. Third, people bring a lifetime of experience in learning from and teaching others and naturally do quite a lot to socially structure appropriate learning environments and interactions so that others can learn efficiently and effectively. Personal robots should be able to leverage these social interactions to also learn efficiently and effectively from people. The hypothesis that we investigate in this paper concerns the structure of social behavior and embodied interaction that we term "social filters:" dynamic, embodied cues through which the teacher can guide the behavior of the robot by emphasizing and de-emphasizing objects in the environment. Specifically, we conjecture that action timing and "spatial scaffolding" are two important kinds of social filters - simple, natural, and prevalent non-verbal cues in which teachers time their actions and use their bodies to structure the learning environment to direct the attention of the learner. The challenge is to identify when and how these cues are employed in natural learning settings, and how they can be used by a robot to efficiently guide its internal attention and learning processes.
