本文件规定了交互设备数据格式的语法和语义，通过定义基于XML模式的交互信息描述语言（IIDL），为接口致动器和传感器提供了标准格式。IIDL提供了一个基本结构，其中包含与各种执行器和传感器一致通信的公共信息。定义设备命令词汇表（DCV）是为了提供一种标准化的格式来命令单个执行器，定义传感信息词汇表（SIV）是为了提供一种标准化的格式来保存来自单个传感器的信息，以便从真实世界获取环境信息，或者基于IIDL使用获取的信息来影响虚拟世界的对象。

This document specifies syntax and semantics of the data formats for interaction devices by providing a standardized format for interfacing actuators and sensors by defining XML schema-based language named Interaction Information Description Language (IIDL). IIDL provides a basic structure with common information for communication with various actuators and sensors in consistency. Device Command Vocabulary (DCV) is defined to provide a standardized format for commanding individual actuator, and Sensed Information Vocabulary (SIV) is defined to provide a standardized format for holding information from individual sensors either to get environmental information from real world or to influence virtual world objects using the acquired information on the basis of IIDL.
