Representing Experiences of Digital Systems: The Design and Use of Externalising Models

This is a PhD by practice that explores how people’s experiences of digital systems can be made physically and visually apparent using models and activities I have designed. The theoretical context for this PhD centres on internal and external models of people’s experiences with digital systems. This is an AHRC funded PhD written as part of the Creative Exchange, which supports collaborative research projects conducted with industry and academic partners. My primary research question focuses on the design characteristics of visual and physical models that externalise individual and group experiences of digital systems. Secondary questions include: What effects do the material properties of externalising models have on how digital systems are represented? and What types of activities externalise representations of digital systems? These questions are explored through case studies that focus on a set of digital systems identified through the research including web browsing, digital social networks, and image metadata. The first two case studies are exploratory, the third is applied
