360 Degree Video - Videos or still images that have been captured in a full 360 degree field of view allowing you to tilt or pan right the way round the scene, though they are not usually stereoscopic. They can be viewed through a VR headset for an immersive experience, though an app may be required.

Augmented Reality (AR) - The projection of computer generated images on top of an image of the real world. Very popular and useful on modern smartphones (Pokémon Go!) but can also work with headsets such as Google Glass.

Head Mounted Display (HMD) - HMDs, also known as headsets, are devices worn on your head with an integrated display for projecting computer generated imagery. Virtual reality headsets cover both eyes and often have built in headphones for a more immersive experience, whereas augmented reality headsets may only cover one eye so that the image can be projected over what you are seeing in the real world.

Immersive Technology - Any technology which creates an effect of embedding you into a virtual world, such as a combination of a head mounted display and headphones.

Mixed Reality (MR) - An advanced form of augmented reality which allows you to physically interact with objects in both the real world and computer generated objects overlaid onto the real world.

Stereoscopic - A technique for creating the illusion of a field of depth (3D) by projecting a slightly different image to each eye. Used in virtual reality headsets.

Virtual Reality (VR) - A computer generated 3D world which a person can be inserted into by using various immersive technologies, typically at least a head mounted display.
