Information about common technologies


Virtual reality

Virtual reality (VR) is a 3D computer-generated environment which can be a highly imaginative, or a realistic, simulation of the actual world. Depending on the VR environment, people can interact through first-person (through their own eyes or the eyes of a character) or through third person (disembodied) perspectives, or they can switch between the two.

VR can be delivered via a desktop computer, mobile computing device or with a head-mounted display (HMD), which can be a headset or goggles.


Teachers need to consider the safe use of VR with students. As a first step, teachers should consult and follow manufacturers’ guidelines.

Augmented reality

Augmented reality (AR) allows computer-generated information and virtual objects to be overlayed on physical object in real time. AR is a relatively young technology in terms of mass adoption. AR can be delivered by via desktop computers, projector systems, mobile devices, such as smart phones and tablets, and head mounted displays (headsets, goggles or glasses). The most common type of AR is that delivered through mobile devices such as tablets and smart phones.
