Abstract

A method for resolving and operating POI stacks in a virtual environment displayed on an image screen surface, automatically scales, upon selecting a first POI stack with a first quantity of POI'"'"'s contained in the POI stack, the representation of the virtual environment such that POI'"'"'s contained in the first POI stack are displayed on the image screen surface such that individual POI'"'"'s, when correctly positioned in the virtual environment, maintain a minimum size and a minimum distance to respective neighboring POI'"'"'s, and, if the minimum distance cannot be maintained, a partial quantity of the quantity of POI'"'"'s of the first POI stack is combined in at least one second POI stack on the basis of the respective position of the individual POI'"'"'s in the virtual environment. A corresponding system is also described.

Claims

1. A method for resolving, operating and displaying POI stacks in a virtual environment displayed on a screen surface, comprising:

when selecting a first POI stack with a plurality of POI'"'"'s contained in the first POI stack, automatically scaling a representation of the virtual environment such that POI'"'"'s contained in the first POI stack are represented on the screen surface so that individual POI'"'"'s maintain a minimum size and a minimum distance to a neighboring POI when correctly positioned in the virtual environment,

when the minimum distance cannot be maintained, combining a subset of the plurality of POI'"'"'s contained in the first POI stack in at least one second POI stack as a function of a respective position of the individual POI'"'"'s in the virtual environment, wherein the minimum distance is formed as a function of a threshold value, which is calculated dynamically and as a function of the available screen surface and of the total number POI'"'"'s to be represented,

displaying the individual POI'"'"'s and the at least one second POI stack on the screen surface,

when the second POI stack is selected by a user, representing the POI'"'"'s contained in the second POI stack and the respective virtual environment in an adapted scale by dividing the second POI stack into its components,

changing and increasing the displayed scale of the geographical map until all or at least a portion of the POI'"'"'s contained in the POI stack can be displayed individually and can be correctly positioned in the virtual environment while still enabling navigation, and

displaying a maximum possible number of POI'"'"'s simultaneously in a meaningful way when correctly positioned in the virtual environment.

2. The method of claim 1, wherein the first POI stack is selected by using an operating logic that is identical to the operating logic used for navigation in the virtual environment.

3. The method of claim 1, wherein the plurality of POI'"'"'s contained in the first POI stack are represented in abstracted form, when scaling of the representation of the virtual environment is insufficient for representing the plurality of POI'"'"'s in the virtual environment at their respective position.

4. The method of claim 1, further comprising

preselecting a POI in the first POI stack that is located closest to a position indicator, and

representing this preselection by an altered crosshair.

5. The method of claim 1, further comprising highlighting a selection of a POI by depicting a visual and logical connection between a selection tool and the selected POI.

6. The method of claim 1, further comprising starting routing to a selected POI upon initiation by a user.

7. A system for resolving, operating and displaying POI stacks in a virtual environment, comprising

at least one display medium for displaying a geographical map and POI'"'"'s contained thereon,

a device for inputting commands from a user that operate the system and enable navigation both on the geographical map and within the POI stack with a control logic,

wherein the system is configured to

when a first POI stack with a plurality of POI'"'"'s contained in the first POI stack is selected by the user, automatically scale the representation of the virtual environment such that POI'"'"'s contained in the first POI stack are represented on the screen surface so that individual POI'"'"'s maintain a minimum size and a minimum distance to a neighboring POI when correctly positioned in the virtual environment,

when the minimum distance cannot be maintained, combine a subset of the plurality of POI'"'"'s contained in the first POI stack in at least one second POI stack as a function of the respective position of the individual POI'"'"'s in the virtual environment,

form the minimum distance as a function of a threshold value, which is calculated dynamically and as a function of the available screen surface and of the total number Pas to be represented,

display the individual POI'"'"'s and the at least one second POI stack on the screen surface,

when the second POI stack is selected by a user, represent the POI'"'"'s contained in the second POI stack and the respective virtual environment in an adapted scale by dividing the second POI stack into its components,

change and increase the displayed scale of the geographical map until all or at least a portion of the POI'"'"'s contained in the POI stack can be displayed individually and can be correctly positioned in the virtual environment while still enabling navigation, and

display a maximum possible number of POI'"'"'s simultaneously in a meaningful way when correctly positioned in the virtual environment.

8. The system of claim 7, wherein a GPS receiver determines a location of the user and transmits the location to the system.
