To create a virtual reality (VR) femoral nailing simulator combining haptics and image intensifier functionality then carry out validation studies to assess its educational value. The consisted of 3D environment, haptic device printed drill handle VR headset. environment was created using video game development engine, interfaced with plugins allow feedback functionality. Two tasks were within ...

We propose an efficient and effective image generation system for an experimental mixed-reality traffice space. Our enhanced traffic/driving simulation system represents the view through a hybrid that combines virtual geometry with real images to realize high photo-reality with little human cost. Images for datasets are captured from the real world, and the view for the simulation system is cre...

Recent research has shown that students should be familiar with computer history. This paper examines three projects whose goals are to bring history of computers and technology into the computer science classroom in innovative and interesting ways – a video of the PDP-11/10, a virtual reality simulator of the ENIAC computer, and a videotaped interview with one of the principal designers of the...

This study describes our experience with using a virtual reality simulator, CricSim, to enhance the training of combat medics to perform a cricothyroidotomy (surgical airway) while in Iraq. Over a six month period, 65 medics used the simulator as part of a Combat Medic Advanced Skills Training class while in Iraq and were asked to evaluate it. Students self-assessed comfort level with the proce...

We are working towards the development of a robotic handheld surgical device for laparoscopic interventions that enhances the surgeons’ dexterity. In this paper, the kinematics of the end effector is studied. Different choices of kinematics are compared during an evaluation campaign using a virtual reality simulator to find the optimal one: the Yaw-Roll (YR) kinematics. A proof of concept proto...

We propose a novel design of a parallel manipulator of Stewart Gough type for virtual reality application of single individuals; i.e. an omni-directional treadmill is mounted on the motion platform in order to improve VR immersion by giving feedback to the human body. For this purpose we modify the well-known octahedral manipulator in a way that it has one degree of kinematical redundancy; name...

For a number of years, simulators have been used in aviation, nuclear power, military flight operations and other industries as a training tool and method to assess performance. Their use is nearly universal in high reliability organizations. Recently the use of simulation in medicine has increased markedly, in part due to greater awareness of the importance of patient safety. Defined broadly, ...

A simulation system for flexible endoscopy is described, based on virtual reality techniques. The physician moves the flexible endoscope inside a pipe, in which forces are applied to it. In addition the navigation wheels provide force feedback from the bending of the endoscope’s tip. The paper focuses on the design and implementation of the special purpose haptic display which actively generate...
