Immersive Electronic

ursued related work formally and informally with multiple collaborators. In 2002, we presented an intermediate summary of results from a three-year effort incorporating teleimmersion technologies into surgical training. Our goal is to create technologies that let surgeons witness and explore a previous surgical procedure in 3D as if they were present at the place and time of the actual event, with the following added benefits: nonlinear control over time; instruction from the original surgeon or other instructor; and integrated 3D illustrations, annotations, and relevant medical metadata. This would let surgeons integrate the technical aspects of the procedure with the anatomy, radiography, and physiology of the patient's condition, thus best simulating and in many ways augmenting the real-time educational experience of learning how to perform an operative procedure.
