Virtual reality (VR) is a computer technology that simulates 3D environments. It lets users interact with virtual environments https://www.iptech.one/the-most-expensive-gaming-pc using different devices. Virtual reality is viewed on mobile device screens as well as virtual reality rooms on headsets, or even in virtual reality goggles. VR also enables users to manipulate 3D models of human bodies as well as the physical environment by using first-person interactions the models, also known as avatars.
In 1968, Ivan Sutherland created a viable head-mounted display at Harvard University (figure 1-17). The system consisted of miniature cathode-ray tubes which gave stereoscopic images to each eye, as well as ultrasonic and mechanical trackers designed to allow users to move around in a digital space. The VR technology platform was developed because of advances in computer graphics and computer processing. 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 high-speed computer used by numerous VR facilities.
It has been demonstrated that VR has the ability to improve knowledge and skills for health professionals education when contrasted with less interactive digital learning programs. However, it’s not yet clear if these effects translate into positive outcomes for patients. VR has also been proven to reduce stress levels in health professionals and patients. Nijland et al. found that ICU nurses who utilized VR relaxation during breaks reported significantly less stress levels than nurses who didn’t use VR. However, it is important to be aware that the duration of the VR application may cause hyperstimulation and cybersickness for some patients.
