Pre-printed surface for handwriting, comprising a pre-printed graphical representation of the passing of a period of time, and associated computer program

1. A stationery system comprising:

a collection of pre-printed surfaces on which handwritten entries can be made, wherein each pre-printed surface comprises

a pre-printed graphical representation of passing of at least one segment of a plurality of segments of a period of time,

at least one entry creation zone for user entry and identification of at least one segment,

at least one pre-printed mark for local identification of the at least one entry creation zone,

at least two pre-printed marks for global identification of the pre-printed surface and which establish reference positions on the pre-printed surface, and

a graphical code comprising

information for identifying, using the graphical code, the respective pre-printed surface within the collection of pre-printed surfaces,

composition of the respective pre-printed surface with respect to arrangement of the at least one entry creation zone, and

dimensional parameters of the pre-printed surface; and

a computer program including a sequence of instructions which, when executed by a computer processor,

process images of respective pre-printed surfaces,

correct perspectives of the images of respective pre-printed surfaces, produced by angled imaging of the pre-printed surfaces, using the pre-printed marks for global identification and the dimensional parameters of the graphical code of the respective pre-printed surface,

identify an entry creation zone in an image of a respective pre-printed surface, using the at least one pre-printed mark for local identification and the at least two pre-printed marks for global identification,

identify on a respective pre-printed surface, within the collection of pre-printed surfaces, a handwritten entry created by the user in an entry creation zone and corresponding to a segment, and

create a time entry in a database associated with an electronic planner, based on identifying of the handwritten entry created by the user, using the segment appearing in the entry creation zone.

2. The stationery system according to claim 1 , wherein

the at least one pre-printed mark for local identification comprises a plurality of pre-printed marks for local identification, and

each pre-printed mark for local identification facilitates identification of a respective subdivision of the entry creation zone and corresponding to a respective segment of the period of time.

3. The stationery system according to claim 1 , wherein the at least one pre-printed mark for local identification comprises a mark facilitating identification of a subdivision of the entry creation zone situated centrally on the pre-printed surface.

4. The stationery system according to claim 1 , wherein the at least one pre-printed mark for local identification helps in identifying a border of the at least one entry creation zone.

5. The stationery system according to claim 1 , wherein the at least one pre-printed mark for local identification comprises at least one mark at a head and at least one mark at a foot of an entry creation zone elongated parallel to a pre-printed graphical representation of the passing of the period of time.

6. The stationery system according to claim 1 , wherein

the at least one pre-printed mark for local identification comprises at least three marks along an entry creation zone elongated parallel to the pre-printed graphical representation of the passing of the period of time, and

the at least three marks are separated from one another along the entry creation zone elongated parallel to the pre-printed graphical representation of the passing of the period of time.

7. The stationery system according to claim 1 , wherein

the at least one entry creation zone is elongated parallel to the pre-printed graphical representation of the passage of the period of time, and

the at least one pre-printed mark for local identification identifies the at least one entry creation zone in a direction perpendicular to elongation of the entry creation zone that is elongated.

8. The stationery system according to claim 1 , wherein the pre-printed graphical representation of the passing of the period of time comprises a printed scale included in the at least one entry creation zone and printed with a lighter color or lower intensity relative to the at least one pre-printed mark for local identification.

9. The stationery system according to claim 1 , wherein the pre-printed graphical representation of the passing of the period of time comprises a scale printed outside the at least one entry creation zone, at a distance from the at least one pre-printed mark for local identification.

10. The stationery system according to claim 1 , further comprising a zone in which handwritten notes may be entered, wherein the zone in which handwritten notes may be entered is associated in pre-printing with respective segments of the period of time.

11. The stationery system according to claim 1 , wherein

the period of time is equal to three or four days and represents one week over two opposite pages of the pre-printed surfaces, or

the time period is equal to one week shown on a single page of the pre-printed surfaces or two weeks shown on a single page of the pre-printed surfaces.

12. The stationery system according to claim 1 , wherein the collection of the pre-printed surfaces forms a calendar comprising a pre-printed surface in which the period of time is in a range from 3 to 24 months.

13. The stationery system according to claim 1 , wherein the computer program includes a sequence of instructions which, when executed by a computer processor, search for any handwritten entry in the at least one entry creation zone, and, if a handwritten entry is found,

create an electronic entry, in an electronic representation, of the period of time that has been entered, and

associate the electronic entry with the segment of the period of time.

14. The stationery system according to claim 13 , wherein the computer program, when executed, extracts at least one time range by analyzing handwritten entries found in the at least one entry creation zone in a timescale pre-printed on the pre-printed surface.

15. The stationery system according to claim 13 , wherein the computer program, when executed, handles any conflicts between a handwritten entry found on the pre-printed surface and an electronic entry in the electronic representation that has been created.

16. The stationery system according to claim 13 , wherein the computer program, when executed, extracts information from a zone of the pre-printed surface associated with the passing of the period of time, and stores the information in the electronic representation of the passing of the period of time.

17. The stationery system according to claim 13 , wherein the computer program, when executed, creates an alarm to alert a user before beginning of the segment of the period of time.
