Abstract
An audio-based guide arrangement is provided for guiding a user along a target path by the use of stereo audio cues. The user's current location is sensed and compared to the target path. Sounds are fed to the user through left and right audio channels and these sounds are varied to indicate the user's divergence from the target path. In particular, the left and right channel sounds are varied in a complementary manner preferably by increasing the frequency of the sound in one channel whilst simultaneously decreasing the frequency of the sound in the other channel and vice versa.
