Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), eXtended Reality (XR) : Whats The Difference ?

by ATLAS Reality Posted in ATLAS Update

eXtended Reality (XR) refers to technology that improves or replaces our worldview. This is done by superimposing or immersing electronic text and visuals into real-world or virtual settings.

XR includes AR, VR, and MR (MR). All three realities have overlapping characteristics and needs, but distinct goals and technology.

XR will shape the metaverse. The 'next phase of the Internet' will merge real, virtual, and digital worlds via Arm-powered 'gateway' devices like VR headsets and AR smart glasses.

XR technologies are comparable. All XR wearables employ visual input modalities including object, movement, and eye tracking to navigate and display situationally information. Depth and location allow depth perception and mapping.

XR devices differ by kind of VR, AR, and experiences and use case complexity.

Augmented Reality

Augmented reality (AR) improves our perception of the real world by superimposing computer-generated information on top of what we see. This technology is now widely used in smartphone augmented reality apps that enable the user to retain their mobile next to them. The app can display additional context or deliver digital entertainment and social experiences which seem to be grounded in the real world by trying to take the picture from the screen and sorting it in real time.

While smartphone augmented reality has come a long way in the last decade, its applications are still limited. Wearable smart glasses are increasingly being used to deliver a much more holistic AR experience. These gadgets must merge an ultra-low-power cpu with multiple sensors, including visual processing and tracking, all in a light and comfortable form factor that can be worn for long periods of time.

While wearing AR smart glasses, users require always-on, straightforward, and secure navigation. This necessitates significant advancements in depth, geometric distortion, semantic and syntactic, location, alignment, position, present, and gesture and eye tracking, among other features.

Virtual Reality

Virtual reality (VR) replaces the user's vision entirely, immersing them in a pc virtual world. This sort of XR tech has been around for a long time, and it's just gotten better. It's mostly utilized for entertainment events like gaming, concerts, movies, and sports, but it's also making inroads into the social realm. Volumetric capture, HD rendering pipeline, 6DoF motion tracking, and a facial expression capture will all be required for engaging entertainment experiences in VR.

Virtual reality is also employed in training, education, and healthcare, including rehabilitation. VR technology frequently focuses on high-quality video and rendering as well as ultra-low latency to make these experiences viable for the end-user.

Mixed Reality

As it blends the actual and virtual worlds, MR falls midway between AR and VR. For this form of XR technology, there are three main situations. The first method involves using mobile or AR wearable technologies to superimpose virtual items and characters onto real-world settings, or vice versa.

The Pokémon Go mobile game, which debuted in 2016, uses a smartphone camera to overlay virtual Pokémon in real-world locations. This game is sometimes hailed as a game that revolutionizes augmented reality, but it's really a superb example of mixed reality (MR), which combines real-world situations with computer-generated items.

MR is also being utilized to superimpose virtual reality real-world players into video games, bringing real-world characters to game broadcasting platforms like Twitch and YouTube.
