1.1.  Brief Overview of AR/VR Technology

Understanding the differences between Virtual Reality (VR) and Augmented Reality (AR) is necessary before we proceed. Despite the fact that most people confuse and use both names interchangeably, they are entirely different. While an AR developer uses mobile apps to build a layer of digital experience in our reality—such as the game Pokemon Go—a VR developer creates entirely new digital environments that users can see through a device like the Oculus headset.

Therefore, while Augmented Reality (AR) enriches and expands upon our current surroundings, Virtual Reality (VR) transports us to a completely other universe. Additionally, whereas AR does not require headsets—the usage of lenses suffices—VR requires a headset in order to immerse us in the virtual world. As a result, despite their differences, both are expanding quickly in our highly technologically evolved society.

Virtual reality, or VR, is a concept that uses headsets to radically alter your environment and transport you to another place.  To put it simply, it transports you to an entirely new world. You step into a completely new universe in this, one that appears real to you but is actually virtual. It describes the process of creating a virtual world with computer technology, one in which we can experience and live as if we were a part of it. SENSORAMA is referred to as the origin of VR technology. VR examples include Google Cardboard, Galaxy VR, and others.

However, AR can be thought of as virtual reality's next development. It simply adds a display to your existing surroundings rather than altering them. It implies that it enriches the world that already exists. It enhances the real world by adding virtual things in it. As a result, it blends the actual and virtual worlds, earning it the moniker mixed reality. Augmented reality includes apps like Snapchat and games like Pokémon Go. Compared to virtual reality, augmented reality is more expensive.

As mentioned before, businesses outside of the video game industry are also utilizing AR/VR technologies. Additionally, museums are utilizing this technology to offer distinctive visitor experiences. One of the most common uses of augmented reality (AR) is to provide information about art pieces that users can scan with their camera.  Other museums are using technology to present visitors with historical images of the relics or structures. However, it is possible to envision utilizing virtual reality to attend online medical education courses. Without needing to be physically present in a classroom, students can learn about surgeries and medical treatments in a realistic way.

The technologies of Augmented Reality (AR) and Virtual Reality (VR) produce captivating digital experiences that improve and change our lives. Augmented Reality (AR) integrates digital components, such as texts, photos, and videos, into the surrounding actual world. Virtual reality (VR) creates fully virtual experiences that take us to virtual worlds.

Augmented Reality (AR): Experiences range from minimum interaction to completely immersive. Spatial AR is at the lighter end; it modifies our immediate surroundings. AR elements are focused on actual items in object AR total submersion. The smooth merging of virtual and real-world components is made possible by AR. Virtual reality (VR) includes open VR worlds, arcades, movies, and 360-degree experiences. Certain AR applications incorporate location triggers, haptics, audio, images, and multisensory stimulation.

Virtual Reality (VR): In addition to realistic audio specialisation, virtual reality offers an intense visual-spatial experience. Both strive toward more organic interactions, smoother world-to-world transitions, and all-encompassing experiences. Emerging hybrids include AR/VR live streaming, AR movies, and comic books.

Advantages:

Easy-to-use interfaces, captivating experiences, increased productivity, inclusive access, cost/time savings, safety enhancements, and advantages for therapy and education are just a few of the advantages of AR/VR. Distraction, discomfort, privacy/security concerns, and biased/misleading content are among the risks. In order to achieve benefits and prevent putting users or society in danger, development must be done responsibly.

As AR and VR technology progress, they can offer experiences that are immersive, intuitive, and transformative. More expanding fields of view, more precise tracking and response times, lifelike graphics, natural interfaces, multi-sensory stimulation, and better video quality/resolution are some of the improvements. Prices are coming down and capacities are growing, making use more widely available.

AR/VR is improved by integrating it with other technologies, such as artificial intelligence (AI). Through AR/VR experiences, AI offers personalization, education, skill acquisition, remote collaboration, and more. When these technologies are combined, the digital and real worlds around us can offer genuinely immersive, customized, and seamless hybrid experiences.

The development and ethical application of these technologies, advancing humankind rather than abusing its potential, is essential to the advancement of augmented and virtual reality. AR and VR, when used thoughtfully and with intention, can inspire constructive change in the world. However, that journey starts now with each decision made with the greater good in mind above all else.

1.2.  What Exactly is Augmented Reality (AR)?

The ideal fusion of the digital and physical worlds to create an artificial environment is known as Augmented Reality, or AR. AR-enabled desktop and mobile applications that seamlessly integrate digital elements into the physical world. AR stands for Augment Reality in its full form. For instance, augmented reality technology makes it possible to see score overlays during live sporting events and to see 3D images, emails, and texts.

Thus, an interactive experience that blends computer-generated material and the actual world is called Augmented Reality (AR). Multiple sensory modalities, such as visual, aural, haptic, somatosensory, and olfactory, may be covered by the material. Three fundamental components make up augmented reality (AR) systems: a blend of the real and virtual worlds, real-time interaction, and precise 3D registration of virtual and real things. Constructive (i.e., adding to the natural environment) or detrimental (i.e., obscuring the natural environment) sensory information can be superimposed. Because of how well this experience is integrated with the real world, it appears to be an immersed part of it.  In this sense, virtual reality fully replaces the user's real-world surroundings, whereas augmented reality modifies an individual's continuing perspective of a real-world environment. Mixed reality and augmented reality are essentially the same thing. Terminology used to describe computer-mediated reality and extended reality also overlaps.

The main benefit of augmented reality is how elements of the virtual world are integrated with how an individual perceives the real world. This is done by integrating immersive sensations that are interpreted as organic elements of the surroundings, rather than just data being displayed. The Virtual Fixtures system, created in 1992 at the Armstrong Laboratory of the U.S. Air Force, was the first operational augmented reality system that offered users immersive mixed reality experiences. These systems were created in the early 1990s.  The first industries to offer commercial augmented reality experiences were entertainment and gaming. Applications for augmented reality have since spread to commercial sectors like communications, education, healthcare, and entertainment. Content in education can be accessed through mobile picture viewing or scanning.

Augmented reality provides perceptually rich experiences and is used to improve natural environments or situations. Advanced augmented reality technologies (such as object identification, computer vision, and AR camera integration with smartphone apps) enable users to interact with and manipulate their immediate environment digitally. The actual world has information about its things and surroundings superimposed on it. This data may be digital in nature. Any artificial experience that enhances reality or the real world is known as augmented reality. Examples of this include viewing real sensed or measured data, like electromagnetic radio waves, superimposed in precise alignment with one's actual location in space.

The collection and exchange of tacit knowledge is another area where augmented reality has great promise. Real-time augmentation methods are usually applied in semantic contexts with surrounding elements. Sometimes additional information, such as scores over a live video feed of a sporting event, is integrated with immersive perceptual information. This combines the advantages of heads-up displays (HUDs) and augmented reality technology.

1.3.  What Exactly is Virtual Reality (VR)?

A computer-generated simulation of a different reality or universe is known as Virtual Reality, or VR. Video games and 3D films both use it. Using computers and sensory apparatus like gloves and headsets, it helps to immerse the spectator in realistic-looking simulations.

Virtual reality is utilized not only for games and enjoyment but also for science, education, and training. Virtual reality is VR in its entirety.

Pose tracking and 3D near-eye displays are two techniques used in virtual reality (VR) to create a simulated environment that gives the viewer a sense of immersion. Virtual reality has applications in business (virtual meetings), education (medical or military training), and entertainment (video games, in particular). While terminology is still being worked out due to the industry's youth, augmented reality and mixed reality—also known as Extended Reality (XR)—are other discrete forms of VR-style technology.

To provide realistic visuals, sounds, and other sensations that mimic a user's physical presence in a virtual environment, conventional virtual reality systems now use either multi-projected environments or virtual reality headsets. When utilizing virtual reality gear, an individual can look about, move around, and interact with virtual objects or features.

The effect can also be produced in specially built rooms with several huge screens. Virtual reality headsets, which typically comprise of a head-mounted display with a small screen in front of the eyes, are used to achieve this effect. Although audio and visual feedback are commonly included in virtual reality, haptic technology may also provide additional forms of sensory and force feedback.
