Abstract

The method of the present invention allows obtaining location associated information (3) through the use of a telecommunications device (2) and a two-dimensional code (1) in which the information is stored. The information obtained relates to the geographical position of the two-dimensional code (1), i.e., the location (3), as well as to additional data such as a description thereof, a contact telephone number or its opening hours. The information may be presented according to the language preferences of the user, the two-dimensional code (1) having at least three languages, and it being possible to access a repository with a great number of alternatives or to also translate the content if the repository does not contain the translation in any of the selected languages. The translation will be obtained by accessing the repository with a unique key which includes data relating to the geographical position of the location (3).

Claims

1. Method for obtaining location associated information (3), said information being contained in a two-dimensional code (1) close to the location (3), scanning said two-dimensional code (1) through a camera comprised in a telecommunications device (2), said telecommunications device (2) comprising an ordered list of languages in which to display information, characterized in that it comprises the steps of:

decoding the scanned two-dimensional code (1), obtaining a message provided in bytes, wherein;

the first and second bytes relate to a signature,

the third byte corresponds to a status byte,

the fourth, fifth and sixth bytes store information with respect to the latitude coordinate of the point where the two-dimensional code (1) is located,

the seventh, eighth and ninth bytes store information with respect to the longitude coordinate of the point where the two-dimensional code (1) is located,

the tenth byte comprises information with respect to a sequential identification number,

commencing from the eleventh byte, the two-dimensional code (1) comprises information relating to the location (3) of the two-dimensional code (1) in at least three languages,

if at least one language of the ordered list of languages of the telecommunications device (2) coincides with at least one of the languages in which the information relating to the location (3) of the two-dimensional code (1) is stored in the two-dimensional code (1), displaying said information in the language coinciding with the language of highest priority in the ordered list of languages of the telecommunications device (2) together with the longitude coordinate and latitude coordinate data,

if none of the languages of the ordered list of languages of the telecommunications device (2) coincides with the languages in which the information relating to the location (3) of the two-dimensional code (1) is stored in the two-dimensional code (1),

a server is accessed for obtaining a translation of the information relating to the location (3) of the two-dimensional code (1), accessing said translation through a unique key based on status information, latitude coordinate, longitude coordinate and sequential number stored in the message together with the ordered list of languages of the telecommunications device (2).

2. Method according to claim 1, characterized in that in the step for accessing a server to obtain a translation of the information relating to the location (3) of the two-dimensional code (1), the server accesses a repository where there is stored for each unique key the information relating to the location (3) of the two-dimensional code (1) translated to at least three languages, returning the information to the telecommunications device (2) in the language coinciding with the language of highest priority in the ordered list of languages of the telecommunications device (2).

3. Method according to claim 2, characterized in that in the event that there is no information in any of the languages of the ordered list of languages of the device in the repository, an automatic translation of the information relating to the location (3) of the two-dimensional code (1) to the language of highest priority in the ordered list of languages of the device is obtained.

4. Method according to claim 3, characterized in that the step for the automatic translation comprises an intermediate step for translation into a third language, said third language acting as bridge between the information relating to the location (3) and the language of highest priority in the ordered list of languages of the telecommunications device (2).

5. Method according to claim 1, characterized in that the status byte comprises information with respect to the version of the code, the most significant bit of the latitude coordinate and the two most significant bits of the longitude coordinate.

6. Method according to claim 1, characterized in that the tenth byte only stores information with respect to the sequential identification number in its eight bits.

7. Method according to claim 6, characterized in that the eleventh and twelfth byte store information of a first height coordinate with respect to a first height reference of the point where the two-dimensional code (1) is located.

8. Method according to claim 1, characterized in that the tenth byte stores in the first four bits information relating to the sequential identification number and in the second four bits the four most significant bits of a second height coordinate with respect to a second height reference of the point where the two-dimensional code (1) is located, and the eleventh byte comprises the eight least significant bits of the second height coordinate of the point where the two-dimensional code (1) is located.

9. Method according to claim 7, characterized in that the unique key additionally comprises the information of the first height coordinate of the point where the two-dimensional code (1) is located.

10. Method according to claim 8, characterized in that the unique key additionally comprises the information of the second height coordinate of the point where the two-dimensional code (1) is located.
