Abstract (in Japanese) (See Japanese page) 
(in English) Japanese sign language and Pidgin sign Japanese express themselves by coordinating manual signals such as hand shapes，movements and positions with non-manual signals such as mouth gesture，facial expressions and head movements．Manual signals are mainly used to express words，and non-manual signals are used to express grammatical structures such as adverbs and clauses．It is difficult for novice to learn phoneme of non-manual signals because non-manual signals change their meaning depending on the timing of sign language expression．So，many novice neglect learning of non-manual signals．
We extract keyframes in which the locus of manual signals in a sign language video changes significantly for novice to synchronize manual signals and non-manual signals appropriately and to express sign language correctly．Then，by visualizing the amount of change in the head movements included in the keyframes, we are investigating a sign language learning support system that promotes understanding of the coordination and timing gap between manual signals and non-manual signals．In this paper，we focus on head movements such as nodding and shaking head，and investigated how to highlight head movements．As a result of experimental verification using a prototype of this sign language learning support system, we report that significant learning effects were obtained for learning of head movements in both self-assessment by novice learners themselves and assessment by advanced sign language learners．
