The first versions of simulations in the 1900’s were for groups of people to feel a sense of motion with stereo sound, vibrations, and smells. Some years later, the first head mounted virtual display was developed in 1968 that used two cathode ray tubes mounted to a headband.

A VR system consists of human-interfaces, graphics, sensor technology, high-end computing work together to enable a user interact with an artificial computer-generated environment. The traditional medical training methods depend on available cases and patients with health related issues. Although with a VR system many more cases and scenarios are possible that can be repeated without the possibility of hurting live patients. One of the tools is a fluid flow simulation that is generated from CT scans to show motion through an artery (Djukic, Mandic, Filipovic, 2013). VR systems are also used for education and training for difficult surgical procedures such as bone and dental surgery, intubation and oral cavity procedures, eye surgery, and endoscopic surgeries. Each of these simulators provides education for the doctors as well as a way to practice before a difficult surgery (Ruthenbeck, & Reynolds,

Stop Googling: Let's Talk By Sherry Turkle

The advancement of technology that our society has been privileged with, is starting to take over human’s emotions and replace them with those of a robot. When it comes to the discussion of technology, I have mixed feelings because, in my opinion, we do have a great tool in the palm of our hands. However, I also think human emotions and actions are starting to become robot-like. We need to be able to process emotions so that we can better our understanding of not only each other but also ourselves. I strongly think society needs to evict the virtual world and come back to the real world although it is safe to say I personally have a love-hate relationship with technology.

Taneisha Grant's When The Simulated Patient Is For Real

508 Words | 3 Pages

It has been argued that the shift towards patient-conscious medical aid is necessary and that simulation in its widest sense can be used to support this process. However, sensitivity to what we are simulating is essential, especially when simulations purport to address patient perspectives. The essay first reviews the history of medical education "centeredness," then outlines ways in which real and simulated patients are currently involved in medical education. Patient-focused simulation is described as a means of offering patients' perspectives during the acquisition of clinical procedural and surgical skills. The authors draw on their experiences of developing Patient-focused simulation and preliminary work to "authenticate" simulations from patient perspectives.
