Abstract - Virtual Reality is changing the way people perceive reality, interact with people, and understand life. The paper aspires to explain virtual reality, its architecture, and lastly, the rapid growth of VR into most fields. Virtual reality is sprouting into all arenas: from games to health. With every passing day, Virtual Reality progresses toward a state in which there is no difference between what's real and what isn't. While this paper has also pointed out the challenges of VR, like realism and latency, with evolution in AI, displays, and haptics, it would be bona fide to state that a more accessible and realistic VR future is yet to come. As adoption continues to rise, virtual reality will change industries and redefine human- computer interactions.

Key Words: Immersive Experience, Impact, Realism, Human Computer Interactions

1.INTRODUCTION

Virtual Reality (VR) represents a transformative technology that immerses users into a computergenerated,interactive,three-dimensionalenvironment.Over the past few decades, VR has evolved from a concept primarilyassociatedwithsciencefictiontoacriticaltoolin fields such as not only gaming but also in education, healthcare,and industrial training. Theunderlying goal of VR is to simulate real or imagined environments which enables users to interact with them in ways that feel intuitiveandimmersive,oftenusingdevicessuchasheadmounted displays(HMDs), motion controllers, and haptic feedbacksystems.

As technological advancements have made VR more accessible, its potential applications have broadened significantly, expanding it into areas such as virtual trainingsimulations,therapeuticinterventions,andetc.With continued developments in hardware, software, and networkinfrastructureslike5G,VRispoisedtoplayakey role in the future of human-computer interaction, reshaping industries and redefining how we engage with digital content. This review paper explores the architectureofVRsystems,somerecent

applications, how VR impacts us, and future trends that promisetopushtheboundariesofvirtualexperienceseven further.

By examining these aspects, we aim to highlight the growing impact of VR in research and practical applications, as well as the key innovations that are drivingitsrapidadvancement.

1.1 Brief Past

One of the earliest and most notable milestones in VR history was the creation of the "Sensorama" by Morton Heilig in 1962. Heilig, often referred to as the "Father of Virtual Reality," developed this mechanical device to engage multiple senses and provided an immersive experiencethatpredictedwhatVRwouldlaterbecome.

In 1968, Ivan Sutherland, another VR pioneer, introduced the first head-mounted display (HMD), known as the "SwordofDamocles."

Presence in Virtual Reality on almost all articles describes the sensation of truly "being there" in a virtual environment, despite knowing it is computergenerated.Itactsonapsychologicalstatewhereusersfeel fullyimmersedandinteractnaturally,asifthevirtualworld werereal.

1.3 Types of VR

Stimulating the user’s presence, the VR technology can be generalizedintomajorthreetypes:

 FullyimmersiveVR

 SemiimmersiveVR

 MobileVR

These types reflect the varying levels of immersion and interaction,cateringtodifferentneedsandindustries.

2. VR Architecture

The architecture consists of several interconnected components that work together to create immersive and interactivevirtualenvironments.Here’sabreakdownhow thesegmentationoccursinfollowingway:

3. How VR Impacts us

3.1 Brain Simulation

Virtual Reality acts as a brain simulator, immersing users in environments that trick the senses into perceiving the virtual as real. By providing carefully crafted sensory inputs visual, auditory, and tactile VR engages the brain's natural processes for interpreting reality, triggering emotional and physical reactions similar to thoseinreallife.

VR effectively blurs the line between the virtual and real, demonstrating how easily the brain can be influenced to experiencethingsthatdon’tphysicallyexist.

Virtual Prosthetics

Virtual Reality (VR) can be beneficial for amputees by leveraging principles from the ‘Rubber Hand Illusion’ to enhance body ownership and sensory integration. The "rubber hand illusion," whereby a virtual hand replaces the real hand of the user and stroking of the virtualhand thusinducesanillusoryfeeloftouchupontherealhand.

By using VR to simulate the presence and movement of a virtual limb, amputees can receive visual feedback that alignswiththeirremainingsensations.VRtherapycan also aid in rehabilitation by allowing amputees fostering both physicalandpsychologicalrecovery.
