Virtual reality (VR) is a computer technology that creates 3D environments. It allows users to interact with virtual environments using various devices. Virtual reality is viewed on mobile devices, head-mounted displays, or virtual reality goggles. VR also enables users to manipulate 3D models of human bodies and their physical environments through first-person interactions with the models, also known as avatars.
Ivan Sutherland, a Harvard University professor in 1968, designed a head-mounted display that was viable (figure 1-17). The system consisted of miniature cathode ray tubes that offered stereoscopic images for each eye, and ultrasonic and mechanical trackers designed to let users move around in a digital environment. The advancement of the VR technology platform has been driven by the advancements in computer processing and the development of new computer graphics technologies. Oxford Medical Systems, the precursor to Vicon Motion Systems, develops the first commercial motion capture (MoCap) system in 1984. Silicon Graphics, Inc. creates the VLSI Graphics Engine that provides an extremely fast workstation that has been used by many VR facilities for decades.
It has been demonstrated that VR has the ability to improve knowledge and skills for health professionals’ education when in comparison to less interactive online learning interventions. However, it’s not certain if these benefits translate into outcomes for patients. VR has also been shown to reduce stress among health professionals and patients. Nijland et al. found that ICU nurses who utilized VR relaxation during breaks reported significantly less stress than nurses who did https://www.iptech.one/the-most-expensive-gaming-pc not utilize VR. However, it is important to realize that the length of the VR application can lead to hyperstimulation or cybersickness among some patients.
