Virtual reality (VR) is a computing technology that simulates 3D environments. It allows users to interact with virtual worlds using different devices. Virtual reality can be experienced on https://www.iptech.one/what-is-a-virtual-data-room mobile device screens, virtual reality rooms of head-mounted displays or virtual reality goggles. VR allows the user to interact with 3D models of bodies and spaces in a first-person perspective. These models are called avatars.
Ivan Sutherland, a Harvard University professor in 1968, developed a head-mounted display system that was a viable option (figure 1-17). The system was comprised of miniature cathode-ray tubes that created stereoscopic images of each eye, and ultrasonic and mechanical trackers designed to let users move around in a virtual environment. The advancement of the VR technology platform has been driven by advances in computer processing and the development of new computer graphics technology. Oxford Medical Systems (the predecessor to Vicon Motion Systems) develops the first commercial Motion Capture (MoCap) system in 1984. Silicon Graphics, Inc. creates the VLSI Graphics Engine that provides a high-speed workstation used by many VR facilities for years.
VR has been shown to enhance knowledge and skills in the field of health professions education as compared with less interactive digital learning strategies, but it is not certain if these results translate into patient-related outcomes. VR has been proven to reduce both the health care provider and the patient stress. Nijland et al found that ICU nurses who used VR relaxation during breaks experienced less stress than nurses who didn’t use VR. However it is important to understand that the duration of the VR application may cause overstimulation and cybersickness in some patients.
