Abstract

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.

Claims

1-18. -18. (canceled)

19. A device for control of an electronic equipment item by manipulation of graphical objects, the device comprising:

a display screen;

a transparent multicontact touch sensor for acquisition of multicontact touch information items produced by a plurality of pointing means; and

an electronic control circuit configured to generate control signals according to the touch information items and to generate graphical objects on the display screen, each of the graphical objects being associated with at least one specific processing rule, each of the touch information items being an object of a specific processing determined by its location relative to the position of the graphical objects;

a first series of main graphical objects and a second series of subordinate graphical objects, each of the main graphical objects having a main function and being associated with at least one main specific processing rule, each of the subordinate graphical objects having a subordinate function and being associated with at least one subordinate specific processing rule, the functions of the subordinate graphical objects being complementary to the functions of the main graphical objects, the subordinate graphical objects being disposed on the display screen at locations different from those of the main graphical objects,

wherein the graphical objects are organized such that the first series is manipulated by a first set of pointing means and the second series by a second set of pointing means distinct from the first set of pointing means, and wherein manipulation of at least one of the subordinate graphical objects leads to modifications of properties of at least one of the main graphical objects.

20. A device according to claim 19, wherein one of the properties of at least one of the main graphical objects modified by the manipulation of at least one of the subordinate graphical objects is the display.

21. A device according to claim 19, wherein one of the properties of at least one of the main graphical objects modified by the manipulation of at least one of the subordinate graphical objects is an associated specific processing rule.

22. A device according to claim 19, wherein one of the properties of at least one of the main graphical objects modified by the manipulation of at least one of the subordinate graphical objects is a location on the display screen.

23. A device according to claim 19, wherein the first set of pointing means is manipulated by one hand.

24. A device according to claim 23, wherein the first set of pointing means comprises a stylet manipulated by one hand.

25. A device according to claim 23, wherein the first set of pointing means comprises at least one finger of one hand.

26. A device according to claim 23, wherein the second set of pointing means is manipulated by one hand.

27. A device according to claim 26, wherein the second set of pointing means comprises at least one finger of one hand.

28. A device according to claim 26, wherein the hands of the first and second sets of pointing means are respectively two different hands of a user.

29. A device according to claim 28, for which the hands of the first and second sets of pointing means respectively comprise a dominant hand and a non-dominant hand, wherein the dominant hand manipulates the main graphical objects and the non-dominant hand manipulates the subordinate graphical objects.

30. A device according to claim 29, wherein a main function of at least one main graphical object is a writing function.

31. A device according to claim 29, wherein a main function of at least one main graphical object is a pointing function.

32. A device according to claim 29, wherein a subordinate function of at least one subordinate graphical object is a function of selection of functions allocated to at least one main graphical object manipulated by the dominant hand.

33. A device according to claim 29, wherein the main and subordinate graphical objects are located such that they are closer to the dominant hand and to the non-dominant hand respectively.

34. A device according to claim 29, wherein the electronic equipment item is portable and the non-dominant hand provides support for the electronic equipment item.

35. A device according to claim 19, wherein the position of at least one subordinate graphical object is modified by the user.

36. A device according to claim 19, wherein the acquisition properties are modified according to the first and second sets of pointing means and the main and subordinate graphical objects.
