There are many applications of virtual reality (VR). Applications have been developed in a variety of domains, such as architectural and urban design, industrial designs, restorative nature experiences, healthcare and clinical therapies, digital marketing and activism, education and training, engineering and robotics, entertainment, virtual communities, fine arts, heritage and archaeology, occupational safety, as well as social science and psychology. Virtual Reality (VR) is revolutionizing industries by enabling immersive, interactive simulations that greatly improve the work of professionals in these industries. VR is changing how experts approach problems and come up with creative solutions in a variety of fields, including architecture and urban planning, where it helps visualize intricate structures and simulate entire cities, and healthcare and surgery, where it enhances accuracy and patient safety. As evidenced by successful collaborative operations using VR platforms, advancements in VR enable surgeons to train in risk-free environments and sketch out treatments customized for particular patients. VR applications promote technical proficiency, offer practical experience, and improve patient outcomes by decreasing errors and boosting productivity in medical education. Beyond healthcare, virtual reality (VR) plays a key role in improving education and training through realistic, interactive settings, designing safer workplaces, and producing calming nature experiences. These developments demonstrate VR's ability to revolutionize a variety of industries, but issues like affordability, usability, and realism still need to be addressed. VR also extends its impact into the marketing world, where immersive 3D experiences engage customers in unique ways that get them excited about products. Additionally, VR's role in mental health through therapies for PTSD and anxiety disorders demonstrates its psychological value.
Architecture and urban design One of the first recorded uses of virtual reality in architecture was in the late 1990s when the University of North Carolina virtually modeled Sitterman Hall, home of its computer science department. Designers wore a headset and used a hand controller to simulate moving around a virtual space. With an Autodesk Revit model, they could "walk through" a schematic. VR enables architects to better understand the details of a project, such as the transition of materials, sightlines, or visual displays of wall stress, wind loads, solar heat gain, or other engineering factors. The application of VR expanded from single buildings to city-scale environments during the late 1990s through digital city initiatives. For example, the "Helsinki Arena 2000" project, initiated in 1996, featured a 3D model of the city that served as a technical interface where citizens could communicate via two-way live video within the virtual space. Similarly, Digital City Kyoto (launched in 1998) served as an advanced testbed connecting physical urban environments with virtual spaces, utilizing its 3D virtual city for practical applications such as disaster evacuation simulations using autonomous agents. By 2010, VR programs had been developed for urban regeneration, planning and transportation projects. Entire cities were simulated in VR.
Industrial design Virtual reality and artificial intelligence are used by automotive firms like Porsche and BMW to optimize their production chains. Software developers are building VR solutions to skip redundant design workflow phases and meet end-user expectations faster and more accurately.
Restorative nature experiences
Studies on exposure to nature environments show how they are able to help individuals relax, recover attention capacity and cognitive function, reduce stress and stimulate positive moods. The Attention Restoration Theory and Stress Recovery Theory explain the mechanisms by which VR nature environments can lead to mental restoration. This is in contrast to urban environments that have shown to be less restorative. Immersive virtual reality technology is able to replicate believable restorative nature experiences, either using 360 degree video footage or environments created from 3D real-time rendering, often developed using game engines like Unreal Engine or Unity. This is useful for users who cannot access certain areas, for example, senior citizens or residents of nursing homes who face physical restraints or complications. In 2016, the Southwest Florida Eagle Cam introduced a spherical webcam offering a live immersive virtual reality experience.
Healthcare and medicine VR is being applied to a wide range of medical areas, including medical education, training, surgery and diagnostic assistance for healthcare staff. For healthcare professionals, by exploring computer generated, three-dimensional (3D), multimedia sensory environments in real time, whether realistic or artificial, they can gain practical knowledge that can be used in clinical practice. For patients, VR can be utilised for surgery, rehabilitation and training to alleviate medical symptoms and cure diseases. VR began to appear in rehabilitation in the 2000s.
Training for healthcare professionals With the rise of COVID-19 in 2020, opportunities for clinical training and education were greatly reduced due to the lack of availability of clinical educators and the need to establish social distancing by avoiding in-person interaction. However, in recent years, there has been a resurge in funding, thus, many institutions have developed simulations to teach their medical students. Particularly in the field of diabetes, a study named DEVICE (Diabetes Emergencies: Virtual Interactive Clinical Education) allowed non-specialist clinics to undergo training so that they can better identify and treat diabetes patients.
