The paper describes a method for acquiring and visualizing the Polish Sign Language gestures along with mimic sub code. The software allowing visualization of sign language gestures is one of the modules of the system for the translation of texts written in the Polish language into appropriate messages of the sign language. Proper understanding of the information communicated in the sign language requires the information to be presented in the multipath manner. In addition to the ideographic communication, i.e. gestures of the sign language alone, also lip movement (many deaf people are able to read the movement of the lips) and elements of the mimic sub code expressing emotions and intentions of the sign language users should be taken into account. Additional paths improving quality of the communication are: the text displayed during the gestures visualization and the audio channel through which the speech synthesis is realized (most deaf people are not completely deaf and the sounds they hear support the communication process). In order to obtain the most accurate and the fullest understanding of the content in the sign language all these channels are transmitted simultaneously. The paper describes process of the acquisition of sign language gestures, modeling of face mimicry, representation and storing of the animation data in the database and visualization of this data using 3D avatar.
