In this spirit of simplified interaction with applications and files paper, we examine how the desktop metaphor can be re- and yet better support contemporary knowledge workers’ framed, shifting the focus away from a low-level (and practices by emphasizing activity as the primary organizing increasingly obsolete) focus on documents and applications principle in the interface. Giornata’s enhanced desktop to an interface based upon the creation of and interaction serves not only as a display space for application windows, with manually declared, semantically meaningful activities. but also serves as an active folder for documents and other We begin by unpacking some of the foundational information items associated with the current activity assumptions of desktop interface design, describe an (Figure 1). Giornata utilizes lightweight activity- and activity-based model for organizing the desktop interface document-tagging capabilities that enable informal and based on theories of cognition and observations of real- evolutionary resource organization. Finally, Giornata world practice, and identify a series of high-level system integrates collaboration tools directly into the desktop to requirements for interfaces that use activity as their primary support group information sharing and activity awareness.
