![]() Efficiency, measured as time used to pass the scenario, was best when using the mouse (M = 109.10s, SD = 25.96), followed by gesture-controlled (M = 214.97s, SD = 46.29) and oral instructions (M = 246.33s, SD = 76.50). ![]() Nine standardized scenarios were used.Results30 physicians and senior medical students participated in the experiment. For each group, the order for testing the three modes was randomly assigned. In a crossover randomized controlled trial participants were attributed block wise to six experimental groups. ObjectiveIn this work, we aim at comparing formally three different interaction modes for image manipulation that are usable in a surgery setting: 1) A gesture-controlled approach using Kinect ® 2) oral instructions to a third part dedicated to manipulate the images and 3) direct manipulation using a mouse.Materials and methodsEach participant used the radiology image viewer Weasis with the three interaction modes.
