Abstract

A system and method is disclosed for generating information for use, for example, in a vehicle for guidance of driver. Information is described by information object specifications determined in part from compiled data related to the vehicle and its immediate environment, navigation area, target area, and user profile. An analysis and control part (320, 340) of the system creates information objects, optionally assigns priority to the same, and assigns a medium for presentation of an information object. A system state may be determined related to current use of available media. An information object of high priority can cause the control part to reallocate a medium to allow presentation of the high priority information object. The system may further determine need for format transcoding to allow presentation of information on the most appropriate medium.

Claims

1. A system for producing guiding information for a user in a vehicle, comprising:

means for receiving information from a plurality of information sources;

means for presenting information through a plurality of media

means for processing information from the plurality of said information sources to create a specification of a message comprising at least one information object,

means for determining preferred medium for presentation of said message in a first format, and for determining an alternative medium for presentation of said message in a second format;

means for retrieving information associated with said at least one information object, and

means for output of information associated with said at least one information object for presentation on a selected one of said preferred medium and said alternative medium.

2. The system of claim 1, wherein said means for output comprises

means for transcoding said message into said second format for presentation on said alternative medium, wherein said second format is different from the original first format specified in the message specification.

3. The system of claim 1, wherein said means for output comprises

means for replacing at least one information object by a stored abstraction of the object from a symbol database.

4. The system of claim 1, wherein said information is related to at least one of a vehicle information object, a navigation information object, a user information object and a target information object.

5. The system of claim 4, wherein the navigation information object includes road section objects having at least one of length, service points, road tolls and points of interest.

6. The system of claim 4, wherein the target information object includes a representation of another moving vehicle and said at least one presentation information object includes a representation of an instantaneous route to a meeting place at least fulfilling predetermined characteristics.

7. The system according to claim 1 further comprising:

means for determining a system state, and

means for enforcement of rules applied to the specification of at least one information object and the system state, the rules further being operative to change the system state.

8. The system of claim 7, wherein:

the system state includes allocation of available media to information objects,

said change of system state involving a reallocation of at least one medium.

9. The system of claim 7, wherein said means for enforcement of rules generates a request for transcoding of said at least one information object.

10. A method for producing guiding information for a user in a vehicle capable of receiving information from a plurality of information sources and presenting information through a plurality of media, comprising the steps of:

processing information from a plurality of said information sources to create a specification of a message comprising at least one information object,

determining preferred medium for presentation of said message in a first format and an alternative medium for presentation of said message in a second format;

retrieving information associated with said at least one information object, and

presenting information associated with said at least one information object on a selected one of said preferred medium and said alternative medium.

11. The method of claim 10, further comprising transcoding said message into said second format for presentation on said alternative medium, wherein said second format is different from the original first format specified in the message specification.

12. The method of claim 10, further comprising replacing at least one information object by a stored abstraction of the object from a symbol database.

13. The method of claim 10, wherein said information is related to at least one of a vehicle information object, a navigation information object, a user information object and a target information object.

14. The method of claim 13, wherein the navigation information object includes road section objects having at least one of length, service points, road tolls, and points of interest.

15. The method of claim 13, wherein the target information object includes a representation of another moving vehicle and said at least one information object includes a representation of an instantaneous route to a meeting place at least fulfilling predetermined characteristics.

16. The method according to claim 13, wherein target information in said target information object is changeable in dependence of information in at least one of said vehicle information object, said navigation information object and said user information object.

17. The method according to claim 10, further comprising the steps of:

determining a system state, and

enforcement of rules applied to the specification of at least one information object and the system state, the rules further being operative to change the system state.

18. The method of claim 17, wherein:

the system state includes allocation of available media to information objects, and

said change of system state involves reallocation of medium.
