Interaction patterns for auditory user interfaces
MetadataShow full item record
This paper proposes the use of interaction patterns in the design process of auditory displays in human-computer interaction. To avoid introducing visual concepts in auditory design, a common ground for developing user interfaces without determining their means of representation is proposed. This meta domain allows for the design of user interfaces which can be equally realised in different interaction modalities or multi-modal settings. Although this work focuses on the auditory domain the concept shown is developed keeping in mind that it should be equally applicable in other modalities. A set of mode independent interaction patterns for design in the meta domain are introduced along with their transformation into the auditory domain. A real world application was chosen to evaluate the approach. MS Explorer was analysed, described through the mode independent interaction patterns and transformed into the auditory domain making extensive use of 3D audio rendering techniques. The result, a virtual audio reality version of a file manager, was evaluated with normally sighted persons as well as visually impaired and blind participants showing the feasibility and usability of the approach.
