Abstract

A method, apparatus and computer program for forming graphics in a drawing area based on user instructions. In response to addition or changing of a first graphical object, an interaction zone is formed around the first graphical object for a given continuation period. It is detected if a second graphical object is drawn starting from the interaction zone during the continuation period and if yes, the first graphical object is changed by merging the second graphical object with the first graphical object.

Claims

1. An apparatus, comprising:

an input configured to receive user instructions for forming graphics in a drawing area based on user instructions;

a processor configured to cause;

in response to addition or changing of a first graphical object, forming an interaction zone around the first graphical object an interaction zone for a continuation period; and

detecting if a second graphical object is drawn starting from the interaction zone during the continuation period and changing the first graphical object by merging the second graphical object to the first graphical object, in response to positive detection.

3. The apparatus of claim 1, wherein the processor is configured to form the interaction zone dynamically during the addition or changing of the first graphical object.

4. The apparatus of claim 1, wherein the processor is configured to form the interaction zone dynamically on drawing a line as if using a pen or a brush.

5. The apparatus of claim 1, wherein the processor is configured to form the interaction zone when the first graphical object is completely added or changed.

6. The apparatus of claim 5, wherein the processor is configured to determine the completion of the adding or changing of the first graphical object in response to a pause signal being received from a user.

8. The apparatus of claim 1, wherein the processor is further configured to cause displaying of the interaction zone.

12. The apparatus of claim 1, wherein the processor is configured to form again the interaction zone around the first graphical object in response to detecting a user pointing at the first graphical object.

13. The apparatus of claim 12, wherein the processor is configured to require a further command for the forming again of the interaction.

14. The apparatus of any of claim 1, wherein the processor is configured to operate in parallel with a plurality of first graphical objects.

15. The apparatus of claim 1, wherein the processor is configured to again invoke the interaction zone in response to detecting a re-invoking command and erasing a portion of the first graphical object in response to detecting drawing of a scribble over the first graphical object.

17. A method for forming graphics in a drawing area based on user instructions, comprising:

in response to addition or changing of a first graphical object, forming an interaction zone around the first graphical object an interaction zone for a continuation period; and

detecting if a second graphical object is drawn starting from the interaction zone during the continuation period and changing the first graphical object by merging the second graphical object to the first graphical object, in response to positive direction.

18. The method of claim 17, further comprising causing drawing of a new second graphical object starting from changed interaction zone.

19. The method of claim 17, wherein the interaction zone is formed dynamically during the addition or changing of the first graphical object.

21. The method of claim 17, wherein the interaction zone is formed when the first graphical object is completely added or changed.

24. The method of any of claim 17, further comprising causing displaying of the interaction zone.

29. The method of claim 17, wherein the method further comprises forming again the interaction zone around the first graphical object in response to detecting a user pointing at the first graphical object.

31. The method of claim 17, wherein the method is applied in parallel for a plurality of first graphical objects.

33. The method of claim 17, further comprising subsequently again invoking the interaction zone in response to detecting a re-invoking command and erasing a portion of the first graphical object in response to detecting drawing of a scribble over the first graphical object.

34. The method of claim 33, wherein the detecting of the drawing of the scribble comprises determining at least two lines being drawn in opposing directions over the first graphical object.

36. A computer program stored in a non-transitory computer readable memory medium, comprising computer executable program code which when executed by at least one processor causes an apparatus to perform;

in response to addition or changing of a first graphical object, forming an interaction zone around the first graphical object an interaction zone for a given continuation period; and

detecting if a second graphical object is drawn starting from the interaction zone during the continuation period and if yes, changing the first graphical object by merging the second graphical object to the first graphical object.
