Gesture-based interaction in the operating room can provide surgeons with a way to interact with medical images of the patient in a direct and sterile way as opposed to instructing an assistant. The purpose of this study was to determine whether a modern gesture-based interface using the Kinect is considered desirable and feasible during surgical procedures. To this end, we conducted a usability evaluation on a gesture-controlled medical image viewer with surgeons in a controlled operating room environment in the UMCG Skills Lab. Participants indicated that they would like to incorporate the system in the OR, even though performance measures indicated that the tested system is less accurate and slower when compared to asking an assistant. In a second study, we evaluated two popular gesture-based selection techniques (‘Dwell’ and ‘Push’) because of the importance of selection time and accuracy in surgical tasks. Results from this experiment indicated that the tested techniques were moderately less accurate while selection time was higher for gesture-based selection techniques when compared to the mouse condition. Overall, our studies show that GBI in the operating room is promising but possible refinements include additional functionality, recognition accuracy, more precise cursor control and more ‘natural’ gestures for certain functionality.
