This research proposes a picture card dictionary authoring system to support young language learners perform communicative tasks using daily-life words, without teaching them the vocabulary directly. The system uses a flashcard metaphor, and it provides 3 functions; 1) a teacher creates picture cards by putting the spellings of photos or video taken by learners, 2) stores those cards to the network server as a picture dictionary, and 3) provides an interface to utilize the vocabulary list. These cards will be displayed on an interactive whiteboard, and learners can touch them to hear their pronunciation generated by text-to-speech synthesis, for vocabulary support.
