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 on different devices. Virtual reality is viewed through mobile devices‘ screens as well as head-mounted displays or virtual reality goggles. VR allows users to interact with 3D models of bodies and environments in a first-person manner. These models are known as avatars.
In 1968, Ivan Sutherland created a suitable head-mounted display that was used at Harvard University (figure 1-17). The system consisted of miniature cathode-ray tubes which provided stereoscopic images for each eye, and mechanical and ultrasonic trackers to allow user movement within a digital world. The development of the VR technology platform has been driven by advancements in computer processing and the development of new computer graphics technologies. 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 high-speed workstations used by many VR facilities for years.
VR has been proven to enhance knowledge and skills in the field of health professions education as compared with less interactive digital learning interventions, but it is not clear whether these effects translate into outcomes for patients. VR has also been shown to reduce stress in both health professionals and patients. Nijland et al. found that ICU nurses who used VR during breaks reported significantly less stress levels than nurses who did not utilize VR. It is important to know that the length of VR applications can cause cybersickness and overstimulation in some patients.
