PACALL: Supporting language learning using SenseCam

The authors' research defines a ubiquitous learning log (ULLO) as a digital record of what a learner has learned in the daily life using ubiquitous technologies. In their previous works, the authors proposed a model named LORE (Log - Organize - Recall - Evaluate) to describe the learning process of ULLO and developed a system named SCROLL to implement this model. This paper focuses on Log among 4 factors in LORE and proposed a passive way to log ULLOs. They use SenseCam to capture a learner's learning activities and propose a system named PACALL to support reflection of what s/he has seen. This system filters bad photos that taken by SenseCam and helps learner find learning content. The author use this system in language learning and help learners learn the foreign name of objects around.
