ABSTRACT
We now move down from an analytical scale of decades and years to one of weeks, days, and minutes of designing usage, and follow a series of design meetings in the mechanical design of second-generation Vivago in late 1999 and early 2000. We focus on how usage is shaped in a design process and, in particular, how, in situated action, user-representations enter into design, how they are worked on there, and how they depart from the process of design. To study the entry and transformation of user-representations in design, we examine four interrelated “micro-biographies” of central user-representations in the design of second-generation VivagoWristcare: inventing a new push-button solution, incorporating an LCD screen, creating auto-adjusting width of a bracelet, and that of an attempt to make the surfaces of the device anti-soiling.
