Medical treatments of a surgeon or a dentist are sometimes documented for teaching, telemedicine, or liability issues using a scene oriented video camera. But the most interesting parts of the scene are often covered by the operators hand or body. The best view to the scene is next to the operators field of view or perfectly: Within his head. Head-mounted scene cameras are used to create this exclusive point of view. Eye tracking systems could be used to emphasize the point of gaze within the scene image. The presented system improves classical eye trackers with an additional gaze-driven camera. The resulting scene image maintains the overall context, while the image from the gaze driven camera acts like a magnifying glass and provides a high-resolution image of the gazed detail using an independent exposure, thus creating a high dynamic range image. We show an application in a real dental treatment scenario.
