Abstract:
1. An audio user-interfacing method 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 method comprising the steps of: (a) determining, for each said sound source, an associated rendering position at which the sound source is normally to be synthesized to sound in the audio field; (b) modifying said rendering positions of the sound sources to angularly dilating dilate a region of the audio field set relative to a focus reference by modifying and to adjust said rendering positions of some of the sound sources outside said region to accommodate that region; and (c) generating, using audio output devices, an audio field in which said sound sources, including those outside said region as well as inside, are synthesized at their associated modified rendering positions after any modification effected by step (b).
