Virtual Technology Review

Virtual reality (VR) is a computing technology that simulates 3D environments. It allows users to interact with virtual environments using various devices. Virtual reality is viewed on mobile devices or in virtual reality rooms with head-mounted displays or virtual reality goggles. VR also enables the user to https://www.iptech.one/sega-genesis-mini-hack manipulate 3D models of human bodies and the physical environments through first-person interactions with these models, referred to as avatars.

In 1968, Ivan Sutherland created a feasible head-mounted display at Harvard University (figure 1-17). The system included miniature cathode ray tubes which gave stereoscopic visual images to each eye, and mechanical and ultrasonic tracking to allow user movement within a virtual setting. The advancement of the VR technology platform has been driven by the advancements in computer processing and the creation 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. is the company that develops the VLSI Graphics Engine which offers a high-speed workstation used by many VR facilities for decades.

VR has been proven to increase knowledge and abilities in the field of health professions education as compared with less interactive digital learning programs however it isn’t certain if these results translate into patient-related outcomes. VR has been proven to decrease both patient and health care provider stress. Nijland et al. found that ICU nurses who utilized VR relaxation during breaks reported significantly lower levels of stress compared to those who did not employ VR. It is important to keep in mind that the length of VR applications can trigger hyperstimulation and cybersickness for some patients.
