+ | ==== 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) | ||
