There are various notations for recording the gestures of sign languages (Hamnosys, Stokoe, SignWriting, and others), but none of them are routinely used by deaf people to write in. Such systems have generally been developed by and for people, deaf or otherwise, engaged in the study of sign languages.
Work has been done on recognising signing from video, but it is a very difficult problem and little has been achieved. Translating signing notation to an animated avatar is easier (I’ve been involved with such a project myself), and various demonstration systems have been made, but nothing beyond that.
