Various embodiments relate to remote operator assistance for one or more user commands at a vehicle. A preset number of objects are counted and stored in dedicated chambers, the combination of the numbers of objects within the chambers being known to comprise any number of objects which is desired for dispensing. Viewed in the direction of the transducer wheel, the stop faces are designed relative to one another such that the two diametrically opposed active surfaces of the sensor and of the transducer wheel barely do not touch.
