Augmented Reality for Enterprise Alliance

Key AR terms

Area Glossary

Augmented Reality has been the subject of scientific and engineering research for decades but has only recently been brought to the attention of wider audiences. As the concept is broad, it is easily confused with other new and emerging technologies with which it shares attributes.

The AREA has compiled the following list of key AR terms and their definitions to help enterprises understand what distinguishes AR from other technologies and to provide a helpful reference when reading about AR-specific tools and concepts.

Egocentric Space

Egocentric Space (also known as user-centric space) is one of two reference systems used to map the location of digital content in an AR application. It uses the user’s body and, specifically, the center of the user’s perceptual system, often identified with the head, as the reference point in the AR application. The other reference system, Allocentric Space, uses the object of interest as the reference point.
