本文档定义了一个参考模型和基本组件，用于表示和控制MAR场景中的单个LAE或多个LAE。它定义了概念、参考模型、系统框架、功能以及如何集成2D/3D虚拟世界和LAEs及其接口，以便为MAR应用程序提供LAEs接口。它还定义了在基于LAE的MAR应用程序之间传输和存储LAE相关数据所需的交换格式。 本文件规定了以下功能: a） MAR中LAE的定义； b） 代表LAE； c） LAE属性的表示； d） 感知物理世界中的LAE； e） 将LAE集成到2D/3D虚拟场景中； f） LAE与2D/3D虚拟场景中的对象之间的交互； g） 在MAR场景中传输与LAE相关的信息。 本文档为基于LAE表示的MAR应用程序定义了一个参考模型，用于在MAR场景的2D/3D虚拟场景中表示和交换与LAE相关的数据。它没有定义操作LAE所需的特定物理接口，也就是说，它没有定义特定应用程序需要如何在MAR场景中实现特定LAE，而是定义了用于表示可在MAR应用程序之间互换使用的LAE的通用功能接口。

This document defines a reference model and base components for representing and controlling a single LAE or multiple LAEs in an MAR scene. It defines concepts, a reference model, system framework, functions and how to integrate a 2D/3D virtual world and LAEs, and their interfaces, in order to provide MAR applications with interfaces of LAEs. It also defines an exchange format necessary for transferring and storing LAE-related data between LAE-based MAR applications. This document specifies the following functionalities: a) definitions for an LAE in MAR; b) representation of an LAE; c) representation of properties of an LAE; d) sensing of an LAE in a physical world; e) integration of an LAE into a 2D/3D virtual scene; f) interaction between an LAE and objects in a 2D/3D virtual scene; g) transmission of information related to an LAE in an MAR scene. This document defines a reference model for LAE representation-based MAR applications to represent and to exchange data related to LAEs in a 2D/3D virtual scene in an MAR scene. It does not define specific physical interfaces necessary for manipulating LAEs, that is, it does not define how specific applications need to implement a specific LAE in an MAR scene, but rather defines common functional interfaces for representing LAEs that can be used interchangeably between MAR applications.
