Head motion and eye gaze are general models of natural human interaction. Recent computer vision based head tracking and eye tracking technologies have expanded the possibilities of designing and developing more natural and intuitive user interfaces for a wide range of applications. In this work, we focus on common hands-busy situations in teleoperation activities, where operators often have to control multiple devices simultaneously by hand in order to accomplish operational tasks. This overloads an operator's hand control ability and also reduces productivity. We present an empirical user study comparing head motion and eye gaze as different input modalities for remote camera control when a user is carrying out a hands-busy task. Both objective measures and subjective measures were used for the study. According to the results, we demonstrate the advantages of using gaze for remote camera control in such hands-busy settings.
