Printed Light Tags and the Magic Bookmark
Georgios Bairaktaris, David Mark Frohlich, Radu Alexandru Sporea · 2021
Paper books offer a unique physical feel, which supports the reading experience through enhanced browsing, bookmarking, free-form annotations, memory and reduced eye strain. In contrast, electronic solutions, such as tablets and e-readers, offer interactive links, updatable information, easier content sharing, and efficient collaboration. To combine the best aspects of paper and digital information for reading, we demonstrate two mechanisms for augmenting paper with light sensors that trigger digital links on a nearby smartphone. Light Tags on every page of a book are used in a first demonstration to identify which pages are open. These are replaced with an electronic Magic Bookmark in a second demonstration, avoiding the need to instrument every page.
