A device for controlling an electronic apparatus by handling graphic objects. The device includes a visualisation screen, a transparent multi-contact touch sensor for acquiring multi-contact touch information generated by a plurality of pointing devices, and an electronic control circuit for generating control signals based on the touch information and for generating graphic objects on the visualisation screen. Each of the graphic objects is associated with at least one specific processing rule. Each piece of touch information is subjected to a specific processing determined by the location thereof relative to the position of the graphic objects. A first series of main graphic objects and a second series of subordinate graphic objects respectively have main and subordinate complementary functions associated respectively with at least one main specific processing rule and at least one subordinate specific processing rule. All the graphic objects are arranged such that the first series is handled by a first set of pointing devices and the second series is handled by a second set of pointing devices different from the first set, the handling of at least one of the subordinate graphic objects resulting in modifications of the properties of at least one of the main graphic objects.
