Abstract

An object location indication apparatus which includes a position determination system adapted to determine the position of the apparatus a plurality of audio channels, each connected to an audio output device wherein each channel is associated with a direction, an audio signal supply element adapted to supply an audio component signal to each channel, said plurality of audio component signals in combination providing a substantially continuous composite audio signal, wherein the audio signal supply element modulates each audio component signal depending on the direction of travel required to reach the object from the position determined for the apparatus.

Claims

1. An object location indication apparatus which includes,

a position determination system configured to determine the position of the apparatus relative to the object, and

a plurality of audio channels, each connected to an audio output device, wherein each channel is associated with a direction, and

an audio signal supply element configured to supply an audio component signal to each channel, said plurality of audio component signals in combination providing a substantially continuous composite audio signal, and

an orientation determination system configured to determine the orientation of the apparatus,

wherein the audio signal supply element modulates each audio component signal to each channel depending on the direction of travel required to reach the object from the position determined for the apparatus.

2. An object location indication apparatus as claimed in claim 1 wherein the orientation determination system is provided by an electronic compass.

4. An object location indication apparatus as claimed in claim 1 which is portable.

5. An object location indication apparatus as claimed in claim 1 wherein the composite audio signal delivered by the audio signal supply element is representative of entertainment media.

6. An object location indication apparatus as claimed in claim 1 which is employed to guide a user along a route to an object.

7. An object location indication apparatus as claimed in claim 1 wherein the object is a location.

8. An object location indication apparatus as claimed in claim 1 wherein the object is mobile.

9. An object location indication apparatus as claimed in claim 1 wherein the audio component signal is modulated by having its signal amplitude modified.

10. An object location indication apparatus as claimed in claim 1 wherein the channel associated with the direction required to reach a destination has the audio component signal supplied to it modulating so as to increase the volume of the signal in that channel.

11. An object location indication apparatus as claimed in claim 10 wherein the channel associated with the opposite direction has its volume modulated so as to decrease the volume of the signal in that channel.

12. An object location indication apparatus as claimed in claim 1 wherein the composite audio signal provided is composed of left and right channel audio component signals.

13. An object location indication apparatus as claimed in claim 1 wherein an audio channel is formed from a signal transmission line connected to a speaker.

14. An object location indication apparatus as claimed in claim 1 which includes a pair of audio channels connected to a pair of sound output speakers.

15. An object location indication apparatus as claimed in claim 14 wherein the pair of channels and speakers is formed as a portable headphone set capable of being worn by a user.

16. An object location indication apparatus as claimed in claim 1 wherein the position determination system includes a global positioning satellite (GPS) receiver system.

17. An object location indication apparatus as claimed in claim 1 wherein the position determination includes a cellular telephone receiver.

18. An object location indication apparatus as claimed in claim 1 wherein the position determination system is configured to receive signals from customised beacons.

20. An object location indication apparatus as claimed in claim 1 which includes a user interface element used to control the modulation applied to audio component signals.

21. An object location indication apparatus as claimed in claim 1 which includes a user input system which allows a user to identify a particular object which is to have its location indicated.

22. An object location indication apparatus as claimed in claim 1 including a mapping module containing a model of a geographical region containing the object and the apparatus.

23. An object location indication apparatus as claimed in claim 5 wherein the mapping module incorporates a microprocessor and a memory configured to include a model of the geographical region containing the object and the apparatus.
