LAE Capturer and Sensor

LAE Capturer

• Capturing devices used to capture an LAE in physical world.

LAE Sensor

• Measure various physical properties, interpret and convert the observation into digitals signals related to LAE.

Node for LAE Sensor

Tracker and Spatial Mapper for an LAE

LAE Tracker

• LAE Tracker can track a variety of information that related to LAEs such as real camera information and LAEs themselves in the physical world.
• The spatial mapper for an LAE is to provide spatial relationship information (position, orientation, scale, and unit) between the physical world and the world of the MAR scene by applying the necessary transformations for the calibration of LAEs.

Recognizer and Events Mapper for an LAE

LAE Tracker

• LAE Recognizer is a component that analyzes sensing data related to the representation of an LAE in a MAR world and produces​MAR events and data activated from the LAE through comparison with a local or remote target signal.
• The Event mapper creates the relationship between a MAR event of LAE that obtained from the LAE Recognizer and/or LAE Tracker.

Scene Representation for an LAE

• Scene Representation for an LAE refers to a scene that represents a virtual scene and placeholders. It serves as the implementation structure that combines the physical world scene/objects and the virtual scene/objects.
• It is the observable spatiotemporal organization of physical and virtual objects that have been tracked and recognized by the LAE tracker and LAE recognizer functions.
