Abstract

A method for presenting at least a part of an object is shown, including at least partially dividing at least one object into a plurality of sub-objects, presenting the plurality of sub-objects in a first representation, making at least one sub-object of the plurality of sub-objects an active sub-object, and in response to a user operation on the at least one active sub-object, presenting at least one of the at least one active sub-objects in a second representation. The at least one object may be a 2D object, e.g. a Hypertext Markup Language HTML page or a page of a text document, or a 3D object, e.g. a Virtual Reality Markup Language VRML object, and the display may be integrated in a portable electronic device. A device, a system, a computer program and a computer program product for performing such methods are also provided.

Claims

1. A method comprising:

at least partially dividing at least one object into a plurality of sub-objects;

causing presentation of said plurality of sub-objects in a first representation, determining at least one sub-object of said plurality of sub-objects to be made an active sub-object;

making said at least one sub-object of said plurality of sub-objects an active sub-object; and

in response to a user operation on said at least one active sub-object, causing presentation of at least one of said at least one active sub-objects in a second representation, wherein said at least partially dividing at least one object into a plurality of sub-objects comprises element-wise rendering elements contained in said at least one object to obtain a rendered object with a height, a width, and a depth, checking if a product of the height, the width, and the depth size of said rendered object exceeds a threshold, and forming one or more parallelepiped from said rendered object in an instance in which said threshold is exceeded.

2. The method according to claim 1, wherein said at least one object and said sub-objects are 3D-objects.

3. The method according to claim 1, wherein said at least one object is a page, and wherein said sub-objects are areas.

4. The method according to claim 1, wherein in said user operation, at least one of said at least one active sub-objects is selected, and wherein at least said selected sub-object is presented in said second representation.

5. The method according to claim 1, wherein at least two sub-objects of said plurality of sub-objects are made active sub-objects.

6. The method according to claim 1, wherein said at least partial division of said at least one object into said plurality of sub-objects is based on a structure of at least a part of said at least one object.

7. The method according to claim 1, wherein said at least partial division of said at least one object into said plurality of sub-objects is based on a sectioning algorithm.

8. The method according to claim 1, wherein in said first representation, at least one sub-object of said plurality of sub-objects is scaled to a size that is smaller than the original presentation size of said respective sub-object.

9. The method according to claim 1, wherein in said first representation, at least one sub-object of said plurality of sub-objects is cropped.

10. The method according to claim 1, wherein in said first representation, at least one sub-object of said plurality of sub-objects is indicated by an icon.

11. The method according to claim 1, wherein sub-objects of said plurality of sub-objects with a size that is above a size threshold, or that contain an amount of information that is above an information threshold are made active sub-objects, or both.

12. The method according to claim 1, wherein at least one of said at least one active sub-objects is automatically focused, or selected according to a selection criterion, or both.

13. The method according to claim 1, wherein in said second representation, said at least one active sub-object is scaled to a size that is larger than its size in said first representation.

14. The method according to claim 1, wherein within at least one of said sub-objects presented in said first representation, elements can be directly selected by a user.

15. The method according to claim 1, wherein said plurality of sub-objects is composed of different types of sub-objects, and wherein at least one group of sub-objects of a second type is associated with at least one sub-object of a first type.

16. The method according to claim 15, wherein said at least one active sub-object that is present in said second representation is said at least one sub-object of said first type, and wherein in response to a further user operation on said at least one sub-object of said first type, said at least one group of sub-objects of said second type associated with said at least one sub-object of said first type is presented.

17. A device for presenting at least a part of an object, comprising:

means for at least partially dividing at least one object into a plurality of sub-objects;

means for causing presentation of said plurality of sub-objects in a first representation;

means for determining at least one sub-object of said plurality of sub-objects to be made an active sub-object;

means for making said at least one sub-object of said plurality of sub-objects an active sub-object; and

means for causing presentation of at least one of said at least one active sub-objects in a second representation, wherein said means for at least partially dividing at least one object into a plurality of sub-objects comprises means for element-wise rendering elements contained in said at least one object to obtain a rendered object with a height, a width, and a depth, means for checking if a product of the height, the width, and the depth Nee of said rendered object exceeds a threshold, and means for forming one or more parallelepiped from said rendered object in an instance in which said threshold is exceeded.

18. The device according to claim 17, wherein said sub-objects are presented on a display of a portable electronic device.

19. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform:

at least partially divide at least one object into a plurality of sub-objects;

cause presentation of said plurality of sub-objects in a first representation;

determine at least one sub-object of said plurality of sub-objects to be made an active sub-object;

make said at least one sub-object of said plurality of sub-objects an active sub-object; and

in response to a user operation on said at least one active sub-object, cause presentation of at least one of said at least one active sub-objects in a second representation, wherein said at least partially dividing at least one object into a plurality of sub-objects comprises element-wise rendering elements contained in said at least one object to obtain a rendered object with a height, a width, and a depth, checking if a product of the height, the width, and the depth size of said rendered object exceeds a threshold, and forming one or more parallelepiped from said rendered object in an instance in which said threshold is exceeded.

20. The apparatus according to claim 19, further configured to check if at least one edge of at least one or more said formed parallelepiped is not straight, and forming a smaller parallelepiped from said rendered object if at least one edge is not straight.

21. A computer program product comprising at least one

non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising:

program code instructions for at least partially dividing at least one object into a plurality of sub-objects;

program code instructions for causing presentation of said plurality of sub-objects in a first representation;

determining at least one sub-object of said plurality of sub-objects to be made an active sub-object;

program code instructions for making said at least one sub-object of said plurality of sub-objects an active sub-object; and

in response to a user operation on said at least one active sub-object, program code instructions for causing presentation of at least one of said at least one active sub-objects in a second representation, wherein said program code instructions for at least partially dividing at least one object into a plurality of sub-objects comprises program code instructions for element-wise rendering elements contained in said at least one object to obtain a rendered object with a height, a width, and a depth, program code instructions for checking if a product of the height, the width, and the depth size of said rendered object exceeds a threshold, and program code instructions for forming one or more parallelepiped from said rendered object in an instance in which said threshold is exceeded.

22. The computer program product of claim 21, further comprising program code instructions for checking if at least one edge of at least one or more said formed parallelepiped is not straight, and program code instructions for forming a smaller parallelepiped from said rendered object if at least one edge is not straight.
