This paper provides a novel approach for training in collaborative environment by integrating collaborative virtual environment (CVE) and haptic joystick. Active World is used as the CVE and Novint Falcon is the preferred haptic device to send force back to the user(s). As our test scenario, we consider cardiopulmonary resuscitation (CPR) skills training(More)
OBJECTIVES We present a dental training system with a haptic interface that allows dental students or experts to practice dental procedures in a virtual environment. The simulator is able to monitor and classify the performance of an operator into novice or expert categories. The intelligent training module allows a student to simultaneously and proactively(More)
Central venous catheter related complications are a large burden on our healthcare system. Many of these complications can be prevented by the use of proper technique. One methodology to aid in the teaching non-technical aspects of procedures, serious games, has not been utilized in our field. The authors therefore set out to design a serious game aimed at(More)
BACKGROUND Advanced Cardiac Life Support (ACLS) is a series of team-based, sequential and time constrained interventions, requiring effective communication and coordination of activities that are performed by the care provider team on a patient undergoing cardiac arrest or respiratory failure. The state-of-the-art ACLS training is conducted in a(More)
– The traditional approach to dental skills training has drawbacks in terms of cost, availability, and lack of real-world cases. We develop a virtual reality (VR) dental training system utilizing a haptic (force feedback) device. We generate three-dimensional surface model of the teeth from patient's data and a realistic model of a dental handpiece with a(More)
The use of virtual reality (VR) training tools for medical education could lead to improvements in the skills of clinicians while providing economic incentives for healthcare institutions. The use of VR tools can also mitigate some of the drawbacks currently associated with providing medical training in a traditional clinical environment such as scheduling(More)
Cerebral venous sinus thrombosis (CVST) is a rare but serious disorder that is associated with a poor clinical outcome. We report a 35-year-old man who had a severe headache and diplopia while climbing Mount Everest. His MR venography showed right transverse and right sigmoid sinus thrombosis. He improved on anticoagulant and symptomatic measures. Cerebral(More)
