Method and arrangement for guiding a user along a target path
First Claim
1. An arrangement for guiding a user along a target path, the arrangement comprising:
- user-location determining means for determining the position of the user relative to the target path;
beacon-location determining means for determining locations at which to position multiple virtual audio beacons such that the audio beacons together form a succession of beacons with each beacon being successively further down said target path onward from the user; and
audio-beacon means comprising audio output devices carried by the user for rendering virtual audio beacons at the locations determined by the beacon-location determining means.

Abstract
An audio-based guide arrangement is provided for guiding a user along a target path by the use of virtual audio beacons. The user'"'"'s current location is sensed and compared to the target path. Sounds are fed to the user, for example through stereo headphones, to simulate one or more audio beacons appearing to be located in a direction at least approximating the direction of the target path onward from the user'"'"'s current position. Preferably, each successive location of the audio beacon is determined by determining a segment onward from the user'"'"'s current position of a piecewise linear approximation to the target path, and setting the apparent location of the beacon at or relative to the end of this segment.
