framework for sensor-based 'Natural Interaction'
OpenNI2 is a framework for getting data to support 'Natural Interaction', i.e. skeleton tracking, gesture tracking, and similar ways of getting data from humans. OpenNI2 provides the interface for physical devices and for middleware components. The API enables modules to be registered in the OpenNI2 framework, which then produce sensory data. OpenNI2 also allows selection of different hardware and middleware modules.
