Crossing spaces: towards cross-media personal information management user interfaces

Nowadays, digital and paper documents are used simultaneously during daily tasks. While significant research has been carried out to support the re-finding of digital documents, less effort has been made to provide similar functionality for paper documents. In this paper, we present a solution that enables the design of cross-media Personal Information Management (PIM) user interfaces helping users in re-finding documents across digital and physical information spaces. We propose three main design requirements for the presented cross-media PIM user interfaces. Further, we illustrate how these design requirements have been applied in the development of three proof-of-concept applications and describe a software framework supporting the design of these interfaces. Finally, we discuss opportunities for future improvements of the presented cross-media PIM user interfaces.
