Extended Reality: XR, VR, AR and 360 Video

Umbrella icon by Freepik on Flaticon.comWhat is Extended Reality (XR)?

Extended reality "is the umbrella term which covers all forms of combined real-and-virtual environments, including augmented reality (AR), virtual reality (VR) and mixed reality (MR)". (Scott Likens, PwC)

You will likely see this acronym used more and more at QUT to encompass a wide variety of immersive, interactive visual media.

Virtual Reality by Bharat from the Noun ProjectWhat is Virtual Reality (VR)?

Virtual Reality (also referred to as VR) may be described as an experience whereby a person uses a computer or headset to transport them into an alternative world. VR usually refers to interactive environments, where the viewer can move around and change things in the virtual world, but is sometimes used to describe animated 360 videos which are non-interactive.

Augmented Reality by Evangeline La from the Noun ProjectWhat is Augmented Reality (AR)?

Augmented Reality (also referred to as AR) is a technology that adds digital enhancements to the physical environment.

Probably the most well-known example of AR is the game Pokémon Go, where players use a mobile app to find the virtual creatures at specific physical locations.

The level of interactivity possible with AR varies widely. Some augmentations can only be viewed, others will respond to the user's input or gestures.

Similarly, AR content may be designed for use via a standard smartphone, or with more advanced devices like smartglasses or a headset that still allows users to see their physical environment.

What is Mixed Reality (MR)?

Mixed Reality (also referred to as MR) is a technology that uses a combination of both Virtual Reality and Augmented Reality.

In a nutshell, MR allows the viewer to see virtual objects that appear real, accurately mapped into the real world. - Kharis O'Connell (2016) Designing for Mixed Reality. Ch 1, para 4.

360° Video by Morgan McIlwain from the Noun ProjectWhat is 360° Video?

4 digital cameras attached around a pole360° videos are videos where the user can turn their head (or viewing window) to see the environment in all directions.

This is usually created by 'stitching' together footage shot from multiple cameras pointing out from a single point, like the 360° camera rig at right. 360° video may also be animated.

Generally 360° video is immersive but not interactive; the user cannot move around the environment, only look around from a fixed point.

360° video can be viewed with any headset for an immersive experience, or on any device screen using click-and-drag to look around.

Below are 360° video tours of the QUT Library on both the Kelvin Grove and Gardens Point campuses. You can interact with the videos to explore all aspects of the image. Just use your mouse or your finger.
