Audio Descriptive Analysis & Mapping of Spatial Sound Displays
نویسندگان
چکیده
This study presents a method termed Audio Descriptive Analysis & Mapping (ADAM) to a study of spatial sound displays. Several subjective tasks were performed including a preference experiment, descriptive language development and lastly scaling of all stimuli based on developed attribute scales. The process associated with the descriptive language and attribute scale development is described in detail. A large number of stimuli (104) were employed comprising of 8 audio recording/reproduction techniques in 13 different sound environments, in an effort to broadly evaluated spatial sound displays. Preference data was submitted to a principle components analysis to study the underlying structure of the data. In order to study how subjective preference is formulated, preference data and direct attribute data were submitted to a preference mapping procedure employing partial least square regression.

Diary in the Sky: A Spatial Audio Display for a Mobile Calendar
We present a spatial audio display technique that overcomes the presentation rate bottleneck of traditional monaural audio displays. Our compact speech display works by encoding message semantics into the acoustic spatialisation. In user testing, this display facilitated better recall of events than a conventional small screen visual display. Moreover, results showed that this mapping aided in ...
متن کاملExploratory Sound Analysis: Sonifying Data about Sound
Sound is commonly analysed subjectively by listening to it. However, when we want to analyse a sound objectively, we often switch domains, and change to visual or numerical displays. While it is likely that, generally speaking, the visual sense dominates other senses, when the data being explored are sound the question naturally arises as to whether these data may be statistically represented i...

We conducted an experiment to evaluate the effectiveness of spatial audio displays on target acquisition performance. Participants performed a visual search task with and without the aid of a spatial audio display. Potential target locations ranged between plus and minus 180 degrees in azimuth and from -70 degrees to +90 degrees in elevation. Independent variables included the number of visual ...

This paper presents the results of an experiment comparing two spatial audio display segmentation techniques by investigating the relative salience of target width versus distance to target in a gesture based spatial audio selection task. The first technique, MINIMAL, occupies as little of the display area as possible with sounds placed as close to each other as possible. The second technique, ...

This paper presents the work on a prototype spatial auditory display. Using high-definition audio rendering a sample application was presented to a mixed group of users with visual disabilities and normal sighted users. The evaluation of the prototype provided insights into how effective spatial presentation of sound can be in terms of human-computer interaction (HCI). It showed that typical ap...
