VR (virtual reality) is a technology based on computers www.iptech.one/the-most-expensive-gaming-pc/ that simulates three-dimensional (3D) environments, allowing users to experience virtual worlds and interact with them using different devices. Virtual reality can be viewed on mobile device screens, virtual reality rooms of headsets, or even in virtual reality goggles. VR also enables users to manipulate 3D models of human bodies as well as the physical environments through first-person interactions with the models, also known as avatars.
Ivan Sutherland, a Harvard University professor in 1968, created a head-mounted display that was a viable solution (figure 1-17). The system consisted of miniature cathode-ray tube that created stereoscopic images of each eye, and ultrasonic and mechanical trackers to allow users to move around in a digital environment. The VR technology platform was developed because of the advances in computer graphics and computer processing. Oxford Medical Systems, the precursor to Vicon Motion Systems, develops the first commercial motion capture (MoCap) system in 1984. Silicon Graphics, Inc. has developed the VLSI Graphics Engine which is a high-speed computer that is used by a variety of VR facilities.
It has been established that VR can improve the knowledge and skills of health professionals’ education if compared to less interactive digital learning activities. However, it is not yet clear if these effects translate into positive outcomes for patients. VR has also been proven to reduce stress in both health professionals and patients. Nijland et al. found that ICU nurses who used VR relaxation during breaks reported significantly lower levels of stress compared to those who did not use VR. However, it is important to understand that the duration of the VR application could cause hyperstimulation or cybersickness among some patients.
