+==== Scenario ====
+The use of one or several cameras can recognize a wide range of activities for equipment less expensive.
+Unfortunatelly these devices are sensitive. They must be fixed and they must to be well calibrated with their associated recognition algorithms.
+The temptation is great to add low cost sensors in the user environment to have more robust detections.
+Nevertheless, this approach drastically increases the combinatorics of possible configurations.
+Also some equipment on moving objects allows to such configurations to vary over time.
+For example, a simple pressure sensor on the cushions of a chair can detect the presence of a seated person. Nevertheless, this chair can move and thus change the inferred position for the seated person.
+A carpet with a pressure sensor as presence detector, bought yesterday, will equally increment the user environment and the capacity of the activity recognition system.
+The recognition system activity should automatically adapt to the appearance / disappearance of new sensors.
+It should still be able to integrate the volley of new measures and merge them for a more robust activity  recognition (with uncertainties evaluation)
