Combining head-mounted and projector-based displays for surgical training

We introduce and present preliminary results for a hybrid display system combining Chapel Hill head-mounted and projector-based displays. Our work is motivated by a surgical training application where it is necessary to simultaneously provide both a high-fidelity view of a central close-up task (the surgery) and visual awareness of objects and events in the surrounding environment. In this article, we motivate the use of a hybrid display system, discuss previous work, describe a prototype along with methods for geometric calibration, and present results from a controlled human subject experiment.
