Interactive Gigapixel Prints : Large , Paper-Based Interfaces for Visual Context and Collaboration

For centuries, large paper information graphics such as maps have been important cognitive artifacts in navigation, architecture, design, engineering, and scientific work. Paper-based work practices leverage the high resolution, low cost, reliability, mobility, and flexibility of paper — yet lack the interactivity afforded by digital technologies. This paper introduces Interactive Gigapixel Prints (GIGAprints), computer controlled large-scale paper displays that afford direct pen-based input. These paper prints are augmented with digital displays, integrating the high spatial resolution but low temporal resolution of wide-format printing with the lower spatial resolution but higher temporal resolution of digital displays. Using large paper displays and digital devices together as an ensemble leverages the relative benefits of each medium; GIGAprints afford both ambient awareness and simultaneous viewing and input from multiple users. The pen-based interaction includes selection, progressive information disclosure, filtering, and annotation. This paper contributes a design space for integrated paper and digital interactions, an infrastructure for creating interactive ensembles of large paper displays and digital devices, and four applications built using our infrastructure, each illustrating points in the design space.
