Abstract

The invention relates to a method for displaying route information for individuals located within a predetermined area, route information units being provided at a plurality of orientation points. The inventive method comprises the following steps: -an individual is identified and at least one destination is defined to which the individual is to be guided; -the individual is detected at least at one route information unit; -information on the route the individual has to take to the desired destination is displayed, the individual being identified in a contactless manner. The invention further relates to a device for displaying route information for individuals.

Claims

1. A method for displaying route information for an individual within a predetermined area, the method comprising the following steps:

wirelessly transmitting a two-dimensional barcode to an identification apparatus for identifying the individual, the identification apparatus having a display unit for displaying the two-dimensional barcode;

identifying the individual by interpreting the two-dimensional barcode and establishing at least one destination to which the individual is to be guided;

detecting the individual at at least one route information unit by reading the two-dimensional barcode from the display unit; and

displaying first route information about a further route of the individual to the at least one destination,

wherein the identification of the individual is performed via input in a contactless way of the two-dimensional barcode, and

wherein the first route information is automatically derived from personal data obtained by the identification of the individual.

2. The method according to claim 1, wherein the individual is additionally measured biometrically during the identification.

3. The method according to claim 1, wherein the route information is stored in the identification apparatus.

4. The method according to claim 1, wherein the route information is stored centrally for a plurality of individuals.

5. The method according to claim 1, wherein after the individual has reached the at least one destination, second route information is displayed, the second route information relating to a return route of the individual.

6. The method according to claim 1, wherein the first route information is displayed graphically or is output acoustically.

7. A system for displaying route information for individuals within a predetermined area, the system comprising:

a central unit storing information about topography of an area;

multiple route information units provided at orientation points and comprising display units and communication interfaces, the communication interfaces comprising;

communication interface read units, and

assignment units; and

at least one identification unit comprising an identification unit read unit able to read a two-dimensional barcode wirelessly to identify an individual by interpreting the two-dimensional barcode and input a destination, the at least one identification unit having a display unit for displaying the two-dimensional barcode;

wherein the multiple route information units are implemented for a purpose of detecting the individual by reading the two-dimensional barcode from the display unit of the at least one identification unit;

wherein the display units of the multiple route information units display information about a further route of the individual to the destination after detection of the individual;

wherein the communication interface read units can read two-dimensional barcodes in a contactless manner; and

wherein the assignment units derive the route information automatically from personal data obtained by identification of the individual.

8. The system according to claim 7, wherein the at least one identification unit also has a measuring unit implemented for a purpose of biometrically measuring individuals;

and

wherein the multiple route information units have recognition units, the recognition units recognizing individuals on a basis of biometric data.

9. The system according claim 7, wherein the at least one identification unit further comprises a memory for the route information for the individual.

10. The system according to claim 7, wherein the central unit comprises a memory for the route information for a plurality of individuals.

11. The system according to claim 7, wherein the assignment units derive the route information automatically from personal data obtained by legitimization of the individual.

12. The system according to claim 7, wherein the multiple route information units display route information relating to a return route of the individual after the individual has reached the destination.

13. The system according to claim 7, wherein the multiple route information units can graphically display the route information and/or can acoustically output the route information.
