Digital pen technologies bridge the paper-digital divide by enabling user actions on paper to be tracked. Handwritten notes and sketches can be digitally captured. Active areas on paper can be defined that link to digital content and services and users activate them by simply touching them with the pen. Possibilities abound for publishing new forms of interactive documents and providing paper-based interfaces to applications.
We have developed a platform and range of tools to support the rapid prototyping and production of all kinds of interactive paper applications.
iPaper is a framework that supports the rapid development and deployment of interactive paper applications. Active areas can be defined on paper and linked to various forms of digital media and services. By providing an extensive library of active components, users can rapidly develop a wide range of applications without having to do any programming. iPaper was developed as a component of iServer, a general cross-media server, which means that active areas can be linked to and from a wide range of physical and digital media including web pages, images, video, flash animations, databases and RFID tags as well as application programs. »»
iGesture is a general and extensible framework to support the development and deployment of gesture recognition algorithms. The API makes it simple for application developers to define their own gesture-based interfaces. It is device independent and can be used with a mouse, tablet or digital pen as input. »»
Interactive applications are developed by authoring active areas within pages and defining links to digital content and services. Depending on whether the application is a simple paper-based form interface to an existing application or a large-scale cross-media publication, different styles of authoring and publishing are appropriate. We therefore have developed a suite of tools that include support for everything from the manual authoring of active areas and links to full-scale publishing tools that automatically generate printable versions of documents and link definitions based either on a semantic analysis of existing PDF documents or a content publishing approach.
