Background: In this presentation we discuss two examples of how designers use high-fidelity prototypes throughout the design and development of wearable technologies for hearing loss (hearing aid and cochlear implant technologies). These carefully designed and considered prototypes enabled co-design with participants and interdisciplinary teams in a generative way throughout the design and development processes.
Aims: Through the work we aimed to create high quality, aesthetically refined hearing technologies in a collaborative way, with technology users and interdisciplinary teams. The projects drew from a wide range of approaches to involve technology users throughout development, one particularly effective approach was by leveraging the ‘power of prototypes’.
Methods: The projects draw on a mixture of product-focused design, participatory processes (co-design and user centred design), action research and ethnography.
Results: Through our research we found that the use of high fidelity prototypes as generative artefacts in the design of wearable health technologies had an outsized impact on improving final outcomes. These artefacts are part of the design process, yet bringing them into participatory engagements has a defined impact on collaborators and future users.
Conclusions: Use of high fidelity additive manufactured prototypes at all stages of design and development has a positive impact on the ability for technology consumers to participate in technology development processes. The prototypes: provoke feedback and engagement; enable participants to speculate on future uses and forms; and scaffold collaboration across interdisciplinary teams.
