Introduction

This document defines a representation model for real-time human figures and entities (LAE) in mixed and augmented reality (MAR) worlds:

Scope and key concepts: Related terms, definitions, and a common system architecture together constitute the MAR applications, components, systems, services this document defines the representation and rendering of LAE in MAR scenes, as well as the the LAE defines a set of principles, concepts and functions applicable to all current and future MAR standards:

The reference model specifies the necessary functional modules, basic functional requirements, relevant information content, and the information that should be provided and (or) supported information models: Including (but not limited to) the following:

---Introduction to the fields and concepts of mixed and augmented reality standards;

---Representation model of LAE in MAR scene;

---3D modeling, rendering and simulation of LAE in MAR scenes;

---Attributes of LAE in MAR scene;

---Sensing representation of LAE in MAR scenario;

---Interface representation for controlling LAE in MAR scenario;

---Functions and basic components used to control LAE in MAR scenarios;

---Interaction interface between LAE and MAR scenes;

---Interface with other MAR components;

--- Relationship with other standards;

---Example:

The objectives of this document are as follows:

--- Provide a reference model for MAR applications based on LAE representation;

---Use the attributes of LAE to manage and control it in the MAR environment;

---Integrate LAE into 2D and/or 3D virtual scenes in MAR scenes;

---Realize the interaction between LAE and 2D and/or 3D virtual scenes in MAR scenes;

---Provide the exchange format required to transfer and store data between (LAE-based) MAR applications:

This document has the following document structure:

---Chapter 4 describes the concept of LAE-based systems represented in MAR;

---Chapter 5 explains how sensors can capture LAE in the physical and virtual worlds;

---Chapter 6 describes the mechanism for tracking the position of the LAE and specifies the spatial mapper between physical space and MAR space:

---Chapter 7 describes the mechanism for identifying LAE behaviors and defines the MAR events of LAE and the MAR content creator specified the association between conditions or events;

---Chapter 8 describes a LAE-oriented scenario, which consists of virtual scenes, sensor data, spatial scenes, events, targets, etc:;

---Chapter 9 describes how the MAR scene system renders scenes, LAE maps, events, etc:, so that they can be displayed on a given display device:

--- Chapter 10 describes types of displays, including monitors, head-mounted displays, projectors, tactile devices, and sound output devices:

Equipment, used to display LAE in MAR scene;

---Chapter 11 identifies and describes virtual LAEs, such as virtual 3D models (avatars) and virtual LAEs (such as those in MAR systems):

--- Chapter 12 states any issues related to system performance in the LAE of the MAR;

--- Chapter 13 states any issues related to operational safety in the LAE in the MAR;

--- Chapter 14 states any consistency-related issues with LAE in MAR;

--- Appendix A gives examples of representative LAE representation systems in MAR:

1 Scope

This document defines a reference model and basic constructs for representing and controlling a single LAE or multiple LAEs in a MAR scenario:

The concept, reference model, system framework, functions and how to integrate 2D/3D virtual world and LAEs and the interface between them are defined:

It also defines the transmission and storage of LAEs between MAR applications based on LAE:

The exchange format required to store LAE related data:

This document specifically describes the following features:

a) Definition of LAE in MAR;

b) representation of LAE;

c) Representation of LAE attributes;

d) LAE's perception of the physical world;

e) Integrate LAE into 2D/3D virtual scenes;

f) Interaction between LAE and objects in 2D/3D virtual scenes;

g) Transmit LAE related information in MAR scenarios:

This document defines a reference model for MAR applications based on LAE representation, which is used for 2D/3D virtual scenes in MAR scenarios:

It does not define the specific physical interface required to operate LAE, that is, it does not it does not define how a specific application implements a specific LAE in a MAR scenario, but rather defines a way to represent the LAE that can be used in a MAR application:

Programs can interchangeably use LAE's common functional interface:
