Information technologies applications for sign languages investigations

In the paper the problems of information technologies creation for sign language modeling and investigation are considered. 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 an informational-parametric model has been developed. Efficiency of the developed information technology is shown on realization of Ukrainian sign language. The proposed approach carries a universal character and can be used for modeling of other sign languages.
