Figure 53.1:An overview of the scenario-based design frame- work. Scenarios serve as a central representation throughout the development cycle, first describing the goals and concerns of current use, and then being successively transformed and refined through an iterative design and evaluation process (from Rosson & Carroll,2001b).HCI human–computer interaction.
