Contemporary use of sound as artificial information display is
rudimentary, with little 'depth of significance' to facilitate users'
selective attention. We believe that this is due to conceptual
neglect of 'context' or perceptual background information. This
paper describes a systematic approach to developing 3D audio
information environments that utilise known cognitive
characteristics, in order to promote rapidity and ease of use. The
key concepts are perceptual space, perceptual significance,
ambience labelling information and cartoonification.

In addition, auditory interfaces can now be more easily supported through advanced mobile computing capabilities. Although different types of gesture techniques have been proposed for handheld devices, there is still little knowledge about the acceptability and use of some of these techniques, especially in the context of an auditory interface. In this paper, we propose a novel approach to the problem by studying the design space of gestures proposed by end-users for a mobile auditory interface. We discuss the results of this explorative study, in terms of the scope of the gestures proposed, the tangible aspects, and the users’ preferences. This study delivers some initial gestures recommendations for eyes-free auditory interfaces.
Sonification of Emotion State In Family-Run Businesses

The auditory display is an emotion mapping of the company-family structure, and thereby transmits the emotional impact of possible future scenarios if no intervention takes place. The structural parameters ‘family complexity’, ‘company complexity’, ‘company structure’ and ‘structural risk’ are mapped to structural aspects of the auditory display that contain sufficient similarity to be readily appreciable with minimal preparation. The result is that the implicit emotional state of the analysis subject – a member of the family – is represented in the audio stream. This facilitates other family members’ empathy, because it circumvents subjective semantic interpretations and potential rejection of a purely verbal interpretation of the data. The technique is general and may be applied to other collaborative situations where a self-learning approach is preferred.

The children with dyslexia were slower (p = 0.039) than the CA controls in their reactions to non-verbal auditory onsets (tones), were less able to recognize the first stimulus of a sequence of tones (p = 0.022), and were less accurate in identifying the initial phoneme of a sequence of three (p < 0.001). These characteristics may be manifestations of an impaired temporal processing system for rapid auditory stimuli. CA controls responded more quickly to tone onsets than to tone offsets (p = 0.025), but the dyslexic and RA groups showed no significant difference (p > 0.05) in their reaction times to onsets and offsets of these non-verbal auditory stimuli. Dyslexic readers showed impairment compared with CA controls in responding to the last of a sequence of three non-verbal visual stimuli (shapes), p = 0.02. Reaction times in the visual and auditory onset and offset tasks were richly intercorrelated in the control groups, but the dyslexic group did not show as many significant correlations in reaction times between the auditory and visual domains, or between the onset and offset RTs within each modality. These results suggest that there may be a less integrated cross-modal and intra-modal temporal system in children with dyslexia than in controls. In many of the measures in this study, the performance of the dyslexic group resembled that of the RA control group but differed from CA controls, which implies a developmental delay. The possibility that such a cognitive delay may be related to an underlying neurological disorder is discussed.
