Virtual Reality is one of the latest innovations that change the way people experience their digital world. This technology enables users to enter a computer-generated reality that responds to their inputs and provides them with an immersive experience.
Definition and Overview
Virtual Reality is a technology that creates immersive digital experiences where you can interact with computer-generated simulations that are perceived as real. Unlike traditional modes of display, VR replaces your visual field with a virtual environment that transports you and puts you right in the middle of the action.
In essence, Virtual Reality Technology aims to trick your senses into perceiving virtual elements as real. By simulating a 3D environment and using audio, VR creates an embodied sense of presence, which is a feeling of being physically present and interacting with the surroundings in the virtual environment. This is in contrast to a traditional 2D computer interface that puts you in a position to look at something, not be in it.
Currently, VR has gone from being an experimental technology to becoming a multi-billion-dollar industry with applications in Gaming, Education, Healthcare, Productivity, and more. With new VR devices such as the Meta Quest 3 and Apple Vision Pro, VR experiences are now more accessible than ever.
History of Virtual Reality
The term Virtual Reality was coined by a computer scientist and entrepreneur Jaron Lanier in the 1980s. Lanier founded VPL Research, the first VR company in the world that designed and sold VR hardware. He also pioneered many VR concepts that are in use today. Many corporations such as NASA, automakers, and others were among the first to adopt VPL’s VR technology and systems to develop some of the earliest VR applications.
Key Milestones
The 2010s saw the resurgence of VR with the invention of Oculus Rift by Palmer Luckey. As a teen, Luckey built a prototype from off-the-shelf components that could deliver higher-quality VR at an affordable price. The project’s credibility skyrocketed after renowned game developer John Carmack joined the team. The company successfully raised $2.4M on Kickstarter in 2012, which led to the current VR era.
In 2014, Facebook acquired Oculus for $2B, indicating the tech giant’s interest in the potential of VR to drive the next phase of computing. The acquisition also spurred the entrance of other tech companies such as Google, Sony, Valve, Snapchat, Lenovo, and others into the VR space. Currently, Apple’s new Vision Pro in 2024 marks the end of the experimental phase and catapults VR to the established computing category. Presently, Virtual Reality and Augmented Reality are referred to as Spatial Computing.
How Virtual Reality Technology Works
Virtual Reality technology works by fooling your senses into believing that what you are seeing and hearing is happening in real life. For a convincing simulation, VR headsets had to overcome several challenges such as high-resolution displays, accurate spatial tracking, and 3D spatially rendered audio.
Head Mounted Display (HMD)
VR head-mounted displays or HMDs are the devices that give you a window into the VR world. This is the main component of a VR system which contains several other parts that work together to create an immersive visual and audio experience.
An important Features Of Virtual Reality is the use of OLED panels close to the eye in modern VR HMDs. They operate at 90Hz or higher refresh rates to avoid motion sickness and provide visual comfort while reducing input lag. The display technology works based on optical magnification via Fresnel or pancake lenses to create a wide field of view, with each eye seeing an image on the screen to form a stereoscopic image that replicates natural binocular vision.
Inside the HMDs are tracking sensors such as accelerometers, gyroscopes, and magnetometers that allow the headset to determine the orientation and rotation of the user’s headset. Additionally, most modern VR HMDs use inside-out tracking technology with a set of cameras on the headset. They use computer vision to track the user’s position in the real world to update the graphics and display in real-time.
For a truly immersive experience, hand and controller tracking is essential. Modern VR systems utilize a combination of sensor-based and computer vision-based tracking. In sensor-based VR systems, the controllers have built-in tracking sensors. In computer vision systems, the software tracks the position of your hands and recognizes your gestures.
Virtual Reality (VR) vs Augmented Reality (AR)
Virtual Reality and Augmented Reality are often grouped together under the mixed reality umbrella but have some differences. VR and AR both have similar underlying technological components but differ in the level of immersion they offer to the user. Understanding the differences can help you to know when to use each technology.
Differences between VR and AR
While VR completely transports you to another world, AR overlays digital elements on top of reality. A VR headset typically blocks your view of the real world as it provides you with entirely computer-generated visuals and 3D audio. With VR, you become part of an immersive and interactive virtual world that may take the form of a training simulation or game.
An AR headset, on the other hand, does not replace the real-world environment but adds digital elements on top of it. With AR, you can see the real world but with the addition of digital features such as animated elements, holographic projections, and data visualizations. These digital elements are spatially aware, which means that they can exist in the same space as real-world objects.
Similarities between VR and AR
The two technologies have some components that are similar. For example, both VR and AR devices use display screens and tracking systems. The main difference between AR and VR is the level of immersion, with VR being higher than AR. With VR, you are immersed in a completely different world as it replaces your real-world visual and audio perception. On the contrary, the level of immersion with AR is low as it only adds digital elements to the real world. With current VR headsets, you cannot see real-world objects, but with AR devices, you can.
Another distinction between the two is that VR is generally not spatially aware unless it is a mixed reality headset while AR is inherently spatially aware. In other words, digital elements in AR are aware of their position in real space, which makes it possible for the objects to exist and behave as if they are part of the real world.
In essence, Mixed reality is a term that refers to applications and devices that utilize aspects of VR and AR. It enables users to experience an environment where real-world elements blend with digital elements seamlessly. Unlike VR, mixed reality does not totally immerse the user in computer graphics but rather enhances the real world with digital elements. Additionally, unlike AR, mixed reality is more immersive as it enables the digital elements to interact with the real world.
Extended Reality (XR) and Spatial Computing
Extended Reality or XR is sometimes used to refer to the combined experience of VR, AR, and Mixed Reality. The term XR is a technical way of referring to VR, AR, and Mixed Reality technologies. With the recent launch of Apple Vision Pro, another term used to describe VR and AR is Spatial Computing. In short, Spatial Computing and XR refer to the same technology.
Spatial Computing is a buzzword that encapsulates all the immersive technologies such as VR, AR, and Mixed Reality. It is a term that describes a new era of computing where people can interact with computers in a 3D environment. The term refers to the convergence of digital and physical realities that is made possible by VR, AR, and Mixed Reality headsets. Similarly, XR is also a buzzword used to describe spatial computing by tech companies.
