Abstract

A portable information-providing apparatus comprising a position detector, a direction detector, a processor, a memory, and information output device. The position detector provides data of a use'"'"'s position. The direction detector provides data of a direction as determined by the user. The processor operates to correlate said position and direction data with information of features in the user'"'"'s surroundings as stored in the memory. The information output device provides the information to the user, the information being related to a feature in the user'"'"'s surroundings generally along the direction determined by the user.

Claims

1. A portable information-providing apparatus comprising a position detector which provides data of a user'"'"'s position;

a direction detector which provides data of a direction as selected by the user by pointing the apparatus along a line towards a specific feature of interest within the user'"'"'s general view;

a processor which operates to correlate said position and direction data with a corresponding record of said specific feature of interest in a database containing multiple records associated with different features in the user'"'"'s surroundings, each record comprising data of the position of the feature and user information about the feature; and

an information output device operative to output the user information from the record of said specific feature of interest at which the user has pointed the apparatus.

2. A portable information-providing apparatus according to claim 1, in which the direction detector is separate from the position detector.

3. A portable information-providing apparatus according to claim 2, in which the direction detector defines a three-dimensional direction vector.

4. A portable information-providing apparatus according to claim 3, in which the vector is determined from azimuthal bearing data and angle of inclination data, the direction detector comprising an azimuthal bearing sensor and tilt sensor.

5. A portable information-providing apparatus according to claim 1, in which the direction detector comprises an electronic compass or dead-reckoning module.

6. A portable information-providing apparatus according to claim 1, in which the position detector defines the user'"'"'s position in three dimensional space.

7. A portable information-providing apparatus according to claim 1, in which the position detector includes radio positioning apparatus operative to define the user'"'"'s position.

8. A portable information-providing apparatus according to claim 7, in which the radio positioning apparatus receives satellite and/or terrestrial radio transmissions for positioning.

9. A portable information-providing apparatus according to claim 7, in which the position detector includes a GPS or a dGPS or a CPS CURSOR or a GLONASS receiver.

10. A portable information-providing apparatus according to claim 1, including a target proximity indicator to provide the user with a cue to assist direction selection or pointing in relation to a target feature.

11. A portable information-providing apparatus according to claim 10, in which the indicator provides visual, audible and/or tactile cue(s).

12. A portable information-providing apparatus according to claim 11, in which the indicator comprises a visible light beam that is directed by the user at a target feature and forms a light spot as a visual cue on the feature.

13. A portable information-providing apparatus according to claim 11, in which the indicator responds directly to direction data from the direction detector and provides a visual cue on a “

magic eye”

type indicator or an audio cue.

14. A portable information-providing apparatus according to claim 11, in which in use, the user scans the surroundings with the apparatus to point in different directions, and variations in the cue from the indicator helps guide this pointing activity towards the target feature.

15. A portable information-providing apparatus according to claim 10, in which the target proximity indicator incorporates a sensitivity controller that adjusts directional, lateral, radial or vertical sensitivity of the apparatus dependent upon the distance of target features from the user, the type of features, or spacing of features.

16. A portable information-providing apparatus according to claim 15, in which the sensitivity controller is operative to adjust the directional sensitivity in terms of both azimuth angle and angle of inclination.

17. A portable information providing apparatus according to claim 1, in which the information output device presents the selected information in any suitable form or forms whether visual, audible and/or tactile.

18. A portable information-providing apparatus according to claim 17, in which the information is provided in plain text or natural language.

19. A portable information-providing apparatus according to claim 17, in which the information output device comprises a Braille generating device for the use of the blind and/or deaf-blind.

20. A portable information-providing apparatus according to claim 17, in which the information output means is remote and receives information by radio or infra-red or PAN-type body-modem broadcast.

21. A portable information-providing apparatus according to claim 1, in which the processor operates to provide information to the information output device dependent on a command or commands signal from the user.

22. A portable information-providing apparatus according to claim 21, in which the user presses a button to send a command.

23. A portable information-providing apparatus according to claim 21, in which the apparatus comprises a monitor to monitor eye-blinking of the user and to send a command signal upon an eye-blink being detected.

24. A portable information-providing apparatus according to claim 1, in which the information stored in the memory is supplied on a removable medium.

25. A portable information-providing apparatus according to claim 1, in which the information stored in memory, is enlarged, enhanced or updated by received information broadcast from a remote station.

26. A portable information-providing apparatus according to claim 1, in which the information stored in the memory comprises information of natural features.

27. A portable information-providing apparatus according to claim 1, in which the information stored in the memory comprises information of man-made features.

28. A portable information-providing apparatus according to claim 1, in which the information stored in the memory comprises information of mobile features.

29. A portable information-providing apparatus according to claim 28, in which mobile features send information of their position and identification to a remote station which provides this information to the apparatus.

30. A portable information-providing apparatus according to claim 1, in which information is provided of a feature or features known to have been present at a predetermined time in the past or expected to be present at a predetermined time in the future.

31. A portable information-providing apparatus according to claim 1, further comprising timer means operative to provide timing data to the processor for selection of time-dependent information of features and/or information of features present at other than the present time.

32. A portable information-providing apparatus according to claim 31, in which timing data includes date data.
