A team from Purdue University have developed a system for hands-free image viewing during surgeries. Using Microsoft Kinect 3D cameras, the system is able to continuously track the surgeon and make smart decisions based on the surgeon’s hand movements. The team has worked with veterinary surgeons to come up with a set of hand signals that are natural for clinicians and surgeons. Integrating complex algorithms, the system will be able to distinguish between image viewing commands and other hand gestures. Currently, the system is accurate in translating hand movements approximately 93% of the time.
