5. Narrowing our focus
How to select and classify suitable sounds for a particular
interaction design ?
TaDa - select sounds to communicate the dimensions and
directions with relation to their actions and to that of the
system e.g. ears-lead-eyes design pattern
Sounds linked to physical objects as dynamic entities with
manipulation / interaction
Multidimensional information carrier - size, shape,
material, distance, speed, and emotional expression
6. Selection of Approaches
Evaluating Perceptual Qualities of Single Auditory Stimuli
Identification Tasks, Context-Based Ratings, Attribute
Ratings
Evaluating Relations Among Auditory Stimuli
Discrimination Trials, Similarity Ratings, Sorting Tasks
MDS, CA, PCA, Pathfinder Analysis
Evaluation of application
Surveys, Verbal Protocols, Heuristics
7. Previous studies
Identification percents / Causal Uncertainty metric
Multidimensional scaling based on perceived perceptual
property of sounds
Repertory Grid method
8. Findings from previous studies
Explore if mapping human activity to actions rather than to
objects works for task/domain
Consider the possibility of concurrent auditory presentation
Metaphor from the listener’s own textual responses
Verify your mappings - Proximity ratings, paired
comparisons, or similarity judgements
Visual depiction/s of the human perceptual space
underlying the representation of a set of stimuli can help

intriguing, new sounds
clearly heard - not masked by normal activities of the space
mapping was pleasing as well as attention catching
observations and interviews - contributed to the experience
and was non-intrusive
29. Summary
Many open and unanswered questions...
