Taking the Long View: Structured Expert Evaluation for Extended Interaction

This paper proposes first steps in the development of practical techniques for the expert evaluation of long-term interactions driven by the need to perform expert evaluation of such systems in a consultancy framework. Some interactions are time-limited and goal-driven, for example withdrawing money at an ATM. However, these are typically embedded within longer-term interactions, such as with the banking system as a whole. We have numerous evaluation and design tools for the former, but long-term interaction is less well served. To fill this gap new evaluation prompts are presented, drawing on the style of cognitive walkthroughs to support extended interaction.
