Abstract

Information point having a provider for providing a data structure having entries about different objects, wherein a limited geographical area is associated to every object, and wherein object information is associated to every object, a determiner for determining a geographical position of the information point, an examiner for examining whether the geographical position of the information point lies in the geographical area associated to an object, and a provider for providing object information associated to an object, if the examiner has determined that the information point lies in the geographical area of the object.

Claims

1. An information point, comprising:

a provider for providing a data structure having entries about different objects, wherein a limited geographical area is associated to every object, and wherein object information is associated to every object, and wherein the limited geographical area defines a relevance area, in which the information point has to be so that the object information to which the relevance area belongs can be selected;

a determiner for determining a geographical position of the information point;

an examiner for examining whether the geographical position of the information point lies in the geographical area associated to an object; and

a provider for providing object information associated to an object, if the examiner has determined that the information point lies in the geographical area of the object.

2. The information point according to claim 1, wherein a geographical area associated to an object depends on a topology of the surroundings where the object is located.

3. The information point according to claim 1, wherein a geographical area associated to an object depends on a topology of the surroundings where the object is located and on a geographical area associated to a further object.

4. The information point according to claim 1, wherein an object attribute is associated to a geographical area associated to an object.

5. The information point according to claim 4, wherein the object attribute comprises a selectable object relevance, wherein the selectable object relevance indicates a relevance of the object for a user of the information point.

6. The information point according to claim 1, wherein a geographical area comprises a plurality of subobject areas, which are at different distances to the object, wherein different information is associated to every subobject area.

7. The information point according to claim 1, wherein the determiner for determining the geographical position comprises a GPS receiver.

8. The information point according to claim 1, wherein the determiner for determining the geographical position is implemented to determine a speed of the information point, and wherein the examiner is implemented to determine that the information point lies in the geographical area, when the information point is in the geographical area within a predetermined time interval.

9. The information point according to claim 1, wherein the determiner for determining the geographical position is implemented to detect a speed direction of the information point, and wherein the examiner is implemented to determine that the information point lies in the geographical area, when the object lies within an angle area, determined by a selection angle relative to the driving direction, and to determine that the information point lies outside the geographical area when the object lies outside the angle area.

10. The information point according to claim 1, wherein the determiner for determining the geographical position is implemented to detect a speed direction of the information point, and wherein the examiner is implemented to determine that the information point lies in the geographical area, when the object is located in front of the information point, or to determine that the information point does not lie in the geographical area, when the object is behind the information point.

11. The information point according to claim 9, wherein the provider for providing the data structure is implemented to indicate object information in dependence on a speed or a speed direction of the information point.

12. The information point according to claim 1, wherein a geographical area is defined by a Boolean operation of geometrical forms.

13. A method for information selection, comprising the steps of:

providing a data structure having entries about different objects, wherein a limited geographical area is associated to every object, and wherein object information is associated to every object, and wherein the limited geographical area defines a relevance area, in which the information point has to be so that the object information to which the relevance area belongs can be selected;

determining a geographical position of an information point;

examining whether the geographical position of the information point lies in the geographical area associated to an object; and

providing object information associated to an object if it has been determined that the information point lies in the geographical area of the object.

14. A computer program for performing the method for information selection, comprising the steps of:

providing a data structure having entries about different objects, wherein a limited geographical area is associated to every object, and wherein object information is associated to every object, and wherein the limited geographical area defines a relevance area, in which the information point has to be so that the object information to which the relevance area belongs can be selected;

determining a geographical position of an information point;

examining whether the geographical position of the information point lies in the geographical area associated to an object; and

providing object information associated to an object if it has been determined that the information point lies in the geographical area of the object,

when the computer program runs on a computer.
