Virtual Reality simulators are increasingly used for training novice surgeons. However, there is currently a lack of guidelines for achieving interaction fidelity for these systems. In this paper, we present the design of two navigation techniques for a needle insertion trainer. The two techniques were analyzed using a state-of-the-art fidelity framework to determine their levels of interaction fidelity...
Standard 3D widgets are used for object manipulation in desktop CAD applications but are less suited for use on touchscreens. We propose two 3D constrained manipulation techniques for Tablet PCs. Using finger identification, the dominant hand's index, middle and ring fingers are mapped with the X, Y and Z axes. Users can then trigger different manipulation tasks using specific chording gestures. A...
