There are currently few Virtual Reality simulators for orthopedic trauma surgery. The current simulators provide only a basic recreation of the manual skills involved, focusing instead on the procedural and anatomical knowledge required. One factor limiting simulation of the manual skills is the complexity of adding realistic haptic feedback, particularly(More)
In this paper, we will demonstrate how force feedback, motion-parallax, and stereoscopic vision can enhance the opportunities for learning in the context of dentistry. A dental training workstation prototype has been developed intended for use by dental students in their introductory course to preparing a tooth cavity. The multimodal feedback from haptics,(More)
Natural orifice transluminal endoscopic surgery (NOTES) is a novel technique in minimally invasive surgery whereby a flexible endoscope is inserted via a natural orifice to gain access to the abdominal cavity, leaving no external scars. This innovative use of flexible endoscopy creates many new challenges and is associated with a steep learning curve for(More)
Haptic devices tend to be kept small as it is easier to achieve a large change of stiffness with a low associated apparent mass. If large movements are required there is a usually a reduction in the quality of the haptic sensations which can be displayed. The typical measure of haptic device performance is impedance-width (z-width) but this does not account(More)
