We h a ve d e v eloped a general webcast production model composed of three stages (i.e., sources, broadcast,(More)
Two-dimensional (2D) videoconferencing has been explored widely in the past 15-20 years to support collaboration in healthcare. Two issues that arise in most evaluations of 2D videoconferencing in telemedicine are the difficulty obtaining optimal camera views and poor depth perception. To address these problems, we are exploring the use of a small array of(More)
We present an overview of multi-year efforts aimed at developing technology to support natural telepresence over time for off-line surgical training, and over space for on-line or " live " remote consultation. Our goal is to capture and display high-fidelity, 3D graphical reconstructions of the actual time-varying events, allowing observers to change their(More)
For over a decade we have been pursuing a vision of three-dimensional (3D) telepresence. Our primary driving problem is 3D medical consultation. Our basic goal is to enhance and expand medical diagnosis and treatment for life-critical trauma scenarios by providing an advising health care provider and a distant medical advisee a " live " high-fidelity sense(More)
