In the year 2025, imagine waking up in Pakistan while attending a business meeting in New York through the mesmerizing perception of Extended Reality, the next evolution in human-computer interaction. Extended Reality combines physical and virtual simulated environments, and Virtual Reality (VR) is one of its prominent components. VR allows users to experience three-dimensional scenarios that would otherwise be impossible in reality.It’s a fascinating concept where individuals can immerse themselves in specially designed environments using software and hardware devices. This technology transports users to an artificial world, free from the constraints of reality, with computers serving as gatekeepers to this limitless realm.

Background

The roots of VR can be traced back to 1957 when Morton Heilig, a Hollywood innovator, invented the earliest VR system known as the “sensorama machine.” Heilig wanted to observe people’s reactions to being part of a movie rather than just watching it in cinemas. The sensorama machine provided an immersive simulated city environment that felt remarkably realSince its inception, VR has evolved to its second generation, initially finding applications predominantly in gaming. However, the potential of VR extends far beyond gaming, allowing users to experience and interact with virtual worlds tailored to specific purposes and interests.

Types of Virtual Reality

The man created a deceptive reality-like system that can be categorised into three forms based on the creation type of machines. These types are;

1. Non-immersive VR technology
2. Semi-immersive VR technology
3. Fully immersive  VR Technology

• Non-immersive virtual reality

It is the most common and overlooked type of virtual reality in which. a user interacts directly with computer screens and enjoys VR  in this type of VR a user can handle a few activities and characters only through computer screens. You must have watched children playing games and enjoying the objects’ movements controlled by them,

• Fully immersive VR technology

Many car racing games provide speed and other sensations that are true examples of immersive and interactive situations but fully real-like experiences are yet to be created and around the corner, soon it will be available for further gaming and entertainment purposes.

• Semi-immersive VR technology 

As its name suggests, it can provide a partially believable simulation for educational and trainee purposes to us. Many graphical representations of large projectors are used to teach particular projects to students.

Illusion VR creates

Usually, eyes and brain work in coordination where the eyes see and brain convert visuals into information, memory, learning and perception and send sensations into the body but when it comes to the multidimensional fake world, virtual reality can fool the viewer by creating the same images from two different perspectives and the viewer enjoys the entertaining illusion.

Hardware and Accessories

Without a few devices, it is not possible to take the user into another world, we need controllers, headsets, trackers and different movable treadmills

Let’s discuss a few types of headsets below here;

There are mainly three types of headsets,

1. PC-based VR headsets
2. Standalone headsets
3. Mobile VR headsets

PC-based VR headsets

They are highly prized because of throwing high-quality simulated visuals, powered by external hardware and cable tethered, the display you see built-in motion sensors and a camera tracker assure clear sound and imaginary objects.

• Standalone VR headsets

All-in-one or standalone headsets are wireless and transmit information via mobile and tablets, sometimes wired packed used in a pocket and clipped to clothing.

• Mobile VR headsets

Mobile phones act as VR headsets because lenses separate the screen of smartphones and stereotypic displays have been created, but smartphones are underpowered by gaming consoles.

The other hardware accessories include;

•  3D mouse
•  Optical trackers
• Wired gloves
• Motion controllers
• Omnidirectional treadmills ( ODT)
• Smelling devices

Software used to build VR technology

Without programming its not possible to create illusions to entertain and teach the personals,

Many software developers used,

• Software development kits.
• Content management
• Games engines
• Social platforms
• Training simulators

1. Headsets

Headsets are physical devices and players love to feel the wanted world with fewer essentials so, non-headset technology can destroy the headsets as standards shortly, mobile phones and web browsers are more user-friendly and can attract audiences in a better way

2.  VR and listening

The perceivable images only emulate the desirable world if the audio can resonate with the user’s expectations, so connecting synchronised video and audio can make the optimum VR effects. In the artificial world, the feeling of presence plays a key role and we can induce it more on point if we target the aural sense which is lately called the spatial and binaural audio.

3.  VR created economy

All of us acknowledge the participation of youtube in the socio-economic ecosphere, every one of us is part of youtube directly and indirectly in the start popularity of youtube was not widespread and few people used to share the videos but nowadays we have become video creators, VR technology will replace the simple user interface and have potential to be part of everyone’s life with smartphones because technology will amplify the headsets, VR will enable the storytellers and users to be in other people shoes, and don’t you think that can drag the inclusion, equity, and diversity.

Conclusion

VR has impacted industries ranging from medicine to business and tourism, VR undoubtedly will cover the importance of digitally transforming strategies and the graph of work success can go high if the employees can get training in virtual worlds. No industry will go without this man-created world. Whether it is health, aerospace, entertainment, aviation, art, architecture, Fashion, gaming, dining, manufacturing, museums and marketing and advertising, religion, social media, or support, VR can thrive and manage progress to some extent.
