A large percentage of computing tasks in our contemporary environment are spatial problems carried out on mobile or spatially distributed computing devices. In this chapter, the authors evaluate if and how the commonly established metaphor of a windowed user interface may be adapted in order to suit contemporary usability needs. The study observes user behavior and interactions with a set of large-format touch screens in order to assess user's ability to integrate their interpretation and operation with the displayed information across multiple, spatially distributed screens.
