General Framework for the Rapid Development of Interactive Paper Applications


Published on

Presentation given at CoPADD 2006, 1st International Workshop on Collaborating over Paper and Digital Documents, Banff, Canada, November 2006

ABSTRACT: We present a component-based framework that supports the rapid development of a wide variety of interactive paper applications. The framework includes authoring and publishing tools as well as a server that supports the linking of active areas on paper to a wide range of different media types and services.
