3.1.1

aggregation

relation among objects/components that specifies a whole-part relationship as defined and used in the Unified Modelling Language literature

3.1.2

association

relation among objects/components (and their instances) that they can be linked to each other or combined logically or physically into an aggregation

Note 1 to entry: An aggregation is a specific form of an association as defined and used in the Unified Modelling Language literature.

3.1.3

behaviour

objectorcomponent that describes how certain objects and their attribute values change in time and/or in response to events

3.1.4

content

MAR content

MAR scene

description of mixed and augmented reality based experience to end-users by publishers or media producers

3.1.5

component

MAR component

object

MAR object

self-contained computational entity or model that has one or more input channels and/or one or more output channels

Note 1 to entry: In the context of MAR contents or system, a component has a relevant MAR functionality.

3.1.6

component model

object model

model of a collection of computational objects and their relationships serving a particular purpose or collective function

3.1.7

event mapping

objectorcomponent that maps events produced by the MAR system and maps/relates them to the corresponding ones in the MAR scene/content space

3.1.8

glass-based

type of an optical see-through device that has the form factor of optical glasses

3.1.9

inheritance

association representing a parent and child relationship

Note 1 to entry: In general, the child object, if not specified otherwise, will inherit the attribute model of the parent as defined and used in the Unified Modelling Language literature.

3.1.10

node

term referred to an actual implementation or specific format of an objectorcomponent

3.1.11

optical see-through device

apparatus or device that allows the real/physical world to be seen directly or through optical elements. in addition, the device allows an overlaid display of graphical (or virtual) elements

3.1.12

real transform group

RTG

transform group representing a group of objects situated at a physical/real spatial location

3.1.13

transform

abstract entity representing a relative spatial relationship (translation, rotation and scaling) with another coordinate system (or equally transform)

3.1.14

transform group

tg

component or object that represents a group of objectsorcomponents sharing a common physical or virtual coordinate system

3.1.15

video see-through device

apparatus or device that displays the real/physical world live through a video camera feed

3.1.16

virtual transform group

VTG

transform group representing a group of objects situated at a virtual spatial location
