Virtual Technology Review

VR (virtual reality) is a technology based on computers that simulates three-dimensional (3D) environments, allowing users to explore virtual worlds and interact with them using different devices. Virtual reality can be viewed on mobile devices or in virtual reality rooms with headsets, or even in virtual reality goggles. VR also enables https://www.iptech.one/image-hosting users to manipulate 3D models of human bodies and physical environment through first-person interactions with the models, also known as avatars.

Ivan Sutherland, a Harvard University professor in 1968, created a head-mounted display system that was a viable solution (figure 1-17). The system included miniature cathode-ray tubes that provide stereoscopic visuals for each eye and ultrasonic and mechanical tracking that allowed users to move in a virtual world. The development of the VR technology platform has been driven by technological advances in computer processing and the development of new computer graphics technology. 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 which offers the highest-speed workstation for many VR facilities for decades.

It has been shown that VR can increase knowledge and skills for health professionals’ education if in comparison to less interactive online learning interventions. However, it’s not yet clear if these effects translate into improved outcomes for patients. VR has been demonstrated to reduce patient and health care provider stress. Nijland et al found that ICU nurses who utilized VR relaxation during breaks experienced lower stress levels than those not using VR. However, it is important to understand that the duration of the VR application may cause hyperstimulation and cybersickness for some patients.
