Audio user interface with multiple audio sub-fields
First Claim
1. An audio user-interfacing method in which items are represented in an audio field by respective synthesized sound sources from where sounds related to the items appear to emanate, the method comprising the steps of:
- (a) setting the location of each sound source relative to an associated one of multiple audio-field references;
(b) independently controlling an offset between each audio-field reference and a presentation reference determined by a mounting configuration of audio output devices through which the sound sources are rendered in the audio field, (c) determining a rendering position for each sound source based on its location set in step (a) and the offset of the associated audio-field reference;
(d) rendering said sound sources at their associated rendering positions in the audio field.

Abstract
An audio user interface is provided in which items are represented in an audio field by corresponding synthesized sound sources from where sounds related to the items appear to emanate. The location of each sound source is specified relative to an associated one of multiple audio-field references. The offset of each of these audio-field references relative to a presentation reference is independently controllable whereby to adjust the rendering position of the associated sound sources in the audio field. The offset of each audio-field reference is controlled in response to user input and/or to achieve a particular stabilisation of the associated sound source; this stabilisation may be different for different ones of the audio-field references. One audio-field reference can be dedicated to an audio-cursor sound source. Another audio-field reference can be dedicated to world-stabilised sound sources through which compass direction can be announced.
