FAAST is middleware to facilitate integration of full-body control with games and VR applications. The toolkit relies upon software from OpenNI and PrimeSense to track the user’s motion using the PrimeSensor or the Microsoft Kinect sensors. FAAST includes a custom VRPN server to stream the user’s skeleton over a network, allowing VR applications to read the skeletal joints as trackers using any VRPN client. Additionally, the toolkit can also emulate keyboard input triggered by body posture and specific gestures. This allows the user add custom body-based control mechanisms to existing off-the-shelf games that do not provide official support for depth sensors.
