This paper proposes a Navigator system in ubiquitous learning log system called SCROLL(System for Capturing and Reminding Of Learning Log). Navigator system supports learning in terms of visualization of learning logs stored in SCROLL system. It informs learners of what and where other learners have learned visually and recommend other learning logs which are located close to them and navigate them to the recommended logs. By letting them aware of other learning logs around them and guide to show them where they are located, it provides them more opportunities to learn from experience where they can make discoveries through first-hand observations, instead of reading or hearing about the knowledge. It is thus expected to lead learners to gain more knowledge. © 2012 IEEE.
