This paper examined the relative effectiveness of three communication modalities in a collaborative virtual environment. Communication modalities of verbal only (V), haptic only (H), and both (HV), were used in a 2D pointing task. A total of 36 participants were paired into 18 dyads. In each dyad, there was a supervisor and an acting agent. The supervisor used one of the three modalities to guide...
Minimally invasive surgery uses optical cameras and special surgical tools in order to operate from an environment one step removed from the body cavity of interest to the surgeon. It has been suggested that constraints posed by this arrangement, in particular the lack of direct haptic feedback to the surgeon, may affect the surgeon's ability to identify tissues and accurately maneuver inside the...
To overcome existing barriers in medical robotics education, this paper presents work done during a joint-collaboration project that creates a new educational toolset and associated curriculum for demonstrating telesurgery applications. Created using the LEGO MINDSTORMS NXT robotics set, programmed with LabVIEW, and capable of doing real-time closed-loop control over large distances, the project team...
