The Dual Reality Lab is an experiment aimed at an interface between distributed sensor networks (which collect information about the real world), and online worlds (which allow people to interact and create in a virtual environment). In this case, we are connecting multimodal sensor data taken throughout the Media Lab to events happening in a virtual version of the Media Lab in the online world of Second Life. We hope to discover how data from sensor networks can be used as a creative medium to enhance virtual worlds, and how virtual worlds can act as an intuitive means for browsing sensor data.
