Connected product lifetime extension tokens (CPLET): Eliciting longevity concepts of connected audio products

Abstract

Designing longer-lasting connected products is a complex problem, as they include multiple components such as connectivity chipsets, batteries etc. Discussing longevity concepts with industry experts can therefore be challenging due to a lack of framework and ambiguous terminology. In this paper, we are proposing a tangible token kit called Connected Product Lifetime Extension Tokens (CPLET) that allows us to elicit data in interviews. CPLET includes longevity concepts derived from Design for sustainability and Sustainable ICT literature. We utilized CPLET as conversation enablers during semi-structured interviews with 16 participants from nine different companies in the audio industry. This paper introduces CPLET, and an overview of the longevity concepts currently applied to improve the longevity of connected sound products. Utilising such a complementary method contributed to richness of the data, simulated further reflections. guided and broadened the discussions and mitigated terminology confusion.
