Virtual reality (VR) is a computer technology that simulates 3D environments. It allows users to interact with virtual worlds on different devices. Virtual reality can be viewed on mobile devices or in virtual reality rooms with head-mounted displays, or with virtual reality goggles. VR allows users to 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, developed a head-mounted display system that was a viable solution (figure 1-17). The system consisted of miniature cathode ray tubes that offered stereoscopic images for each eye, as well as ultrasonic and mechanical trackers designed to allow user movement within a digital world. The development of the VR technology platform is fueled by technological 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 utilized by a number of VR https://www.iptech.one/sega-genesis-mini-hack facilities.
It has been demonstrated that VR can improve knowledge and skills for health professionals’ education, when compared to less interactive digital learning techniques. However, it’s not evident if these results translate into improved outcomes for patients. VR has also been proven to reduce stress among health professionals and patients. Nijland et al found that ICU nurses who utilized VR relaxation during breaks experienced significantly lower stress levels than those who did not utilize VR. However it is crucial to recognize that the duration of the VR application could cause hyperstimulation and cybersickness for some patients.
