Common AR terminologies

Learn the common AR terminologies in Adobe Aero to help you get familiar with the terms associated with augmented reality.

Terms used in AR

action :

An action is the "do something" part of a behavior. For example, spin, bounce, and path are actions that an object can take.

anchor :

An indicated 'trackable' point/area that can be used to position AR content. 

ARkit :

Library for AR features provided on iOS devices by Apple.

behavior :

A behavior is an interactive property that can be added to an object in the scene. An object can have zero, one, or multiple behaviors attached. A behavior is made up of a trigger and an action.

bounding box :

A visualization of the extents of an object or selection of objects.

feature points :

Distinct recognizable features of an environment that can be automatically recognized by tracking engines. These are often corners and other joining edges where there is a detectable difference in color from their surroundings.

image anchor :

An image which is used for an AR tracking engine to recognize and attach content to. A good marker image has edges and other visual features. 


(.real) is the Aero document format.

surface :

A real world surface that is trackable by AR. Surfaces are often interpreted by AR apps from a collection of plane-aligned feature points. For example, the surface of a table.

surface anchor :

An anchor that is used to position and orient digital content on a trackable surface.

trigger :

A trigger is part of a behavior. A behavior is usually in a "waiting" state until the trigger tells it to "run".
