in a low-cost camera or partial occlusion of the object. With the Playstation Move,
several of these common problems are addressed on the Playstation 3 console before
the data is ever handed over to the developer.
16.2.2.2 Sensor Fusion
The results of the image analysis are combined with the inertial sensor data using
a modified unscented Kalman filter. The details of this state estimation technique
are beyond the scope of this chapter (though basic common Kalman Filters are pre-
sented later), but there are many excellent explanations available [
