Center node: "Harnessing mobile ubiquitous video"
  Abstract: Realityflythrough is a telepresence/tele-reality system that works in the dynamic, uncalibrated environments typically associated with ubiquitous computing. By opportunistically harnessing networked mobile video cameras, it allows a user to remotely and immersively explore a physical space. Live 2d video feeds are situated in a 3d representation of the world. Rather than try to achieve photorealism at every point in space, we instead focus on providing the user with a sense of how the video streams relate to one another spatially. By providing cues in the form of dynamic transitions, we can approximate photorealistic telepresence while harnessing cameras "in the wild." This paper shows that transitions between situated 2d images are sensible and provide a compelling telepresence experience.
