Supporting ubiquitous learning by linking physical objects and videos

This paper proposes a personal learning assistant called LORAMS (Link of RFID and Movies System), which supports the learners with a system to share and reuse learning experience by linking movies and environmental objects. These movies are not only kind of classes' experiments but also daily experiences movies. LORAMS can infer some contexts from objects around the learner, and search for shared movies that match with the contexts. We improved two functions of the pervious version of LORAMS. One function is to compare the learner's video with the video of a similar situation. By this function, the learner can notice her/his good and bad actions. The other function is to allow the learner to add video annotations. By this function, the learners can obtain information that it's difficult for them to understand from only the video. We think that these videos are very useful to learn various kinds of subjects. We did an experiment (cooking), and we investigated the effect of using the video comparison. Then, we got the result that the learner's performance of doing a task using this comparison system is better than before.
