原文：http://en.wikipedia.org/wiki/OpenNI

OpenNI or Open Natural Interaction is an industry-led, not-for-profit organisation focused on certifying and improving interoperability of natural interaction devices, applications that use those devices and middleware that facilitates access and use of such devices
OpenNI（开放式的自然交互）是一个由业界领导的非营利组织。该组织专注与提高和改善自然交互设备,应用软件的互操作能力。通过使用这些硬件和中间件（软件），来很方便的访问和使用一些设备。

History
The organisation has been created on November 2010, with the website going public on December 8th. One of the main members is PrimeSense, the company behind the technology used in the Kinect
历史
该组织创建于2010年11月，网站与12月8号正式公开。主要成员之一是PrimeSense公司，Kinect的核心芯片正是这家公司提供的。（其他成员还有：开发ROS的机器人公司Willow Garage，以及游戏公司Side-Kick）

Natural Interaction Devices
Natural Interaction Devices or Natural Interfaces  are devices that capture body movements and sounds to allow for a more natural interaction of users with computers  in the context of a Natural user interface. The Kinect and Wavi Xtion are examples of such devices.
自然交互设备
通过捕捉身体动作和声音，自然交互设备允许用户通过自然用户界面来更加自然的和计算机交互。Kinect和Wavi Xtion正是这种设备。

OpenNI Framework
The OpenNI framework provides a set of open source APIs. These APIs are intended to become a standard for applications to access natural interaction devices. The API framework itself is also sometimes referred to by the name OpenNI.
OpenNI框架
OpenNI框架提供一套开源的API接口。这些API接口的目的在于形成一个标准，让应用程序访问自然交互设备倍。API框架本身有时候也被称为OpenNI。

The APIs provide support for
1. Voice and voice command recognition
2. Hand gestures
3. Body Motion Tracking
API接口目前支持：
1. 语音和语音命令识别
2. 手势识别
3. 身体运动追踪
