Abstract
Abstract In a sign-language learning system, the data of sign-language desired by a learner can be outputted quickly and accurately and moreover in the display method matching the requirement of individual learner and the individual learners can easily make additional registration. The sign-language data is preserved in a sign-language dictionary (1) and a desired sign-language data is searched on the basis of an entry word or contents by means of a dictionary search device (2). The searched sign-language data is displayed in a display output device (8) in accordance with a requirement of a learner by means of image synthesis. The sign-language data is registered by a dictionary registration device (3).
