The March 2013 issue of the International Journal of Human-Computer Studies features a clever new technique for automatically (implicitly) bookmarking recently-visited locations in documents, which (as our paper reveals) eliminates 66% of all long-distance scrolling actions for users in active reading scenarios.
The technique, devised by Chun Yu (Tsinghua University Department of Computer Science and Technology, Beijing, China) in collaboration with Ravin Balakrishnan, myself, Tomer Moscovish, and Yuanchun Shi, requires only minimal modification of existing scrolling behavior in document readers — in fact, our prototype works by implementing a simple layer on top of the standard Adobe PDF Reader.
The technique would be particularly valuable for students or information workers whose activities necessitate deep engagements with texts such as technical documentation, non-fiction books on e-readers, or– of course, my favorite pastime– scientific papers.
