Abstract
In a telepresence scenario with remote users discussing a document or a slide, it can be difficult to follow which parts of the document are being discussed. One way to address this problem is to provide feedback by showing where the user's hand is pointing at on the document, which also enables more expressive gestural communication than a simple remote cursor. An important practical problem is how to transmit this remote feedback efficiently with high resolution document images. This is not possible with standard videoconferencing systems which have insufficient resolution. We propose a method based on using hand skeletons to provide the feedback. The skeleton can be captured using a depth camera or a webcam (with a deep network algorithm), and the small data can be transmitted at a high frame rate (without a video codec).
