In this chapter, we present a novel interaction concept for paper-digital hyper-
links. CoScribe supports users in adding own hyperlinks to existing documents in
order to connect printed and digital documents in any combination. Similar to Van-
nevar Bush's early vision of Memex [12], the knowledge worker will be able to cre-
ate a personal Web of information. In contrast to Bush, this closely connects physical
with digital media. Cross-media hyperlinks are not only practical, being faster and
easier to follow, but the conscious selection of passages to be linked supports suc-
cessful learning. By translating contents into higher-level concepts and establishing
relationships between them, learners build structural knowledge, which facilitates
recall and comprehension and is essential to problem solving [51].
As discussed in Chapter 2, several approaches for cross-media hyperlinks have
been presented in the literature. Our concept improves over the literature in several
respects: Previous solutions require the user to switch between different interaction
devices for paper and for digital media. Moreover, they do not integrate hyperlinks
into the larger ecological context of a multi-person-multi-document environment.
Furthermore, existing solutions do not address the collaborative use of hyperlinks.
In contrast, our approach allows the user to create hyperlinks on both media with one
single digital pen and one single pen-based association gesture. Like annotations,
hyperlinks can be shared with other users. An ecological view provides integrated
