Virtual Technology Review

VR (virtual reality) is a technology based on computers that creates three-dimensional (3D) environments that allow users to explore virtual worlds and interact with them through different devices. Virtual reality is viewed via mobile device screens such as head-mounted displays, head-mounted screens, or virtual reality goggles. VR lets users interact with 3D models of the body and environment in a way that is first-person. These models are referred to as avatars.

Ivan Sutherland, a Harvard University professor in 1968, designed a head-mounted display system that was feasible (figure 1-17). The system was comprised of miniature cathode-ray tubes which offered stereoscopic images for each eye, as well as mechanical and ultrasonic trackers to allow users to move around in a virtual environment. The development of the VR technology platform has been https://www.iptech.one/sega-genesis-mini-hack 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., developed the VLSI Graphics Engine which is a super-fast computer used by many VR facilities.

VR has been found to increase knowledge and abilities in health professions education when compared with more inactive digital learning techniques, but it is not clear if these benefits translate into positive outcomes for patients. VR has also been shown to reduce stress in both health professionals and patients. Nijland et al found that ICU nurses using VR relaxation during their breaks experienced significantly less stress than nurses who did not utilize VR. However, it is important to recognize that the duration of the VR application can lead to hyperstimulation or cybersickness among some patients.
