Telepresence robotics is a sophisticated form of robotic remote control in which a human operator has a sense of being on location – that is, of being telepresent. I propose a demonstration of two telepresence robots, one floor model (VGo) and one tabletop model (KUBI). In this proposal, I describe the technology and briefly summarize the research that led to the purchase of the robots. The res...

In this paper we propose an approach to distinguish affordances on a fine-grained scale. We define an anthropomorphic agent model and parameterized affordance models. The agent model is transformed according to affordance parameters to detect affordances in the input data. We present first results on distinguishing two closely related affordances derived from sitting. The promising results supp...

While supportive features that address the needs of students and teachers are critical for the success of educational software, they are only the first step toward adoption and effective use of software in the classroom. As learning technologies gain increasing use in classrooms, designers must pay close attention to the pedagogical and logistical issues that teachers face during their enactmen...
