This thesis investigates the design of audio for feedback in human-technology interaction- auditory displays. Despite promising progress in research and the potential benefits, we currently see little impact of audio in everyday interfaces. Changing interaction paradigms, new contexts of use and inclusive design principles, however, increase the need for an efficient, non-visual means of conveying information. Motivated by these needs, this work describes the development and evaluation of a methodological design framework, aiming to enhance knowledge and skill transfer in auditory display design and to enable designers to build more efficient and compelling auditory solutions. The work starts by investigating the current practice in designing audio in the user interface. A survey amongst practitioners and researchers in the field and a literature study of research papers highlighted the need for a structured design approach. Building on these results, paco - pattern design in the context space has been developed, a framework providing methods to capture, apply and refine design knowledge through design patterns. A key element of paco, the context space, serves as the organising principle for patterns, artefacts and design problems and supports designers in conceptualising the design space. The evaluation of paco is the first comparative study of a design methodology in this area. Experts in auditory display design and novice designers participated in a series of experiments to determine the usefulness of the framework. The evaluation demonstrated that paco facilitates the transfer of design knowledge and skill between experts and novices as well as promoting reflection and recording of design rationale. Alongside these principle achievements, important insights have been gained about the design process which lay the foundations for future research into this subject area. This work contributes to the field of auditory display as it reflects on the current practice and proposes a means of supporting designers to communicate, reason about and build on each other's work more efficiently. The broader field of human-computer interaction may also benefit from the availability of design guidance for exploiting the auditory modality to answer the challenges of future interaction design. Finally, with paco a generic methodology in the field of design patterns was proposed, potentially similarly beneficial to other designing disciplines.
