Beyond paper

TLDR

Reading involves not only viewing words but also underlining, highlighting, and commenting, a practice known as active reading that combines reading with critical thinking and learning. The authors aim to test whether computation can enhance active reading by building the XLibris active reading machine. XLibris uses a high‑resolution pen tablet and a paper‑like interface to let users hold a scanned page and annotate it with digital ink, while automatically monitoring these annotations to organize, search, and retrieve related material in a Reader’s Notebook and margin links. The system shows that computers can aid active readers in organizing and locating information while preserving many benefits of paper reading.

Abstract

Reading frequently involves not just looking at words on a page, but also underlining, highlighting and commenting, either on the text or in a separate notebook. This combination of reading with critical thinking and learning is called active reading [2]. To explore the premise that computation can enhance active reading we have built the XLibris “active reading machine.” XLibris uses a commercial high-resolution pen tablet display along with a paper-like user interface to support the key affordances of paper for active reading: the reader can hold a scanned image of a page in his lap and mark on it with digital ink. To go beyond paper, XLibris monitors the free-form ink annotations made while reading, and uses these to organize and to search for information. Readers can review, sort and filter clippings of their annotated text in a “Reader's Notebook.” XLibris also searches for material related to the annotated text, and displays links to similar documents unobtrusively in the margin. XLibris demonstrates that computers can help active readers organize and find information while retaining many of the advantages of reading on paper.
