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).

On this website you will be able to download the open source OpenNI framework, and get information on third-party hardware and middleware solutions which are OpenNI compliant.
