The following guide, download codes and texts are from http://www.openni.org/, the primary website for the OpenNI Framework which enables the use of Natural Interfrace in various programs and devices. The OpenNI is one of the primary frameworks used by Kinect hackers and developers in utilizing the Kinect’s motion-capture technology into a Natural Interface command panel. We thank the OpenNI.org for sharing this guide.
The OpenNI organization is an industry-led, not-for-profit organization formed to certify and promote the compatibility and interoperability of Natural Interaction (NI) devices, applications and middleware.
As a first step towards this goal, the organization has made available an open source framework – the OpenNI framework – which provides an application programming interface (API) for writing applications utilizing natural interaction. This API covers communication with both low level devices (e.g. vision and audio sensors), as well as high-level middleware solutions (e.g. for visual tracking using computer vision).
