Interactive systems for sign language learning

In the article the problems of communication of deaf people uses sign language are consider. An analysis of sign language information transfer which includes human hands, body, fingers movements, change of mimicry and emotions on human face is brought. Conception is developed and new information technology is proposed for sign language modeling on the base of human spatial model. For the transmission of movements of the real human-informant of sign language on a spatial model technology of motion capture is used. For dactyl alphabet modeling technology that uses a three-dimensional model of a hand based on a informational-parametric model has been developed. Efficiency of the developed information technology is shown on realization of Ukrainian sign language. The proposed approach is carried by universal character and can be used for the modeling of other sign languages.
