SUMMARY
The aim of this study is to present an overview about computer singed language course with module for automatic signed language recognition as a part of language acquisition test. The idea to create an interactive sign language learning system seems to be a new one. We hope that this solution helps to overcome the barrier between the silent and hearing world. On the other hand, we concentrate our efforts to create a system for a home use that will not need any sophisticated hardware. Moreover, we put pressure on utilization of already proposed and popular description scheme. The MPEG-7 standard formally called the Multimedia Content Description Interface has been chosen. This standard provides a rich set of tools for complete multimedia content description. The most important application for sign language is the possibilities to describe static and dynamic features of objects in image sequences both. This description schema gives the opportunity to create description of signing person on required level of granularity. In the article a brief description of many suggested solutions for semiautomatic or automatic sign language recognition systems is given. Besides, there are described some implemented learning application which aim was to learn sign languages. The main groups, which could be distinguished are: animated avatars observation, messenger for deaf people, testing progress in learning sign languages by using education platforms.
