Center node: "swift a signwriting editor to bridge between deaf world and e learning"
  Abstract: SWift (SignWriting improved fast transcriber) is an advanced editor for SignWriting (SW). At present, SW is a promising alternative to provide documents in an easyto- grasp written form of (any) Sign Language, the gestural way of communication which is widely adopted by the deaf community. SWift was developed for SW users, either deaf or not, to support collaboration and exchange of ideas. The application allows composing and saving the desired signs using elementary components called glyphs. The procedure that was devised guides and simplifies the editing process. SWift aims at breaking the "electronic" barriers that keep the deaf community away from ICT in general, and from e-learning in particular. The editor can be contained in a pluggable module; therefore, it can be integrated everywhere the use of SW might is an advisable alternative to written "verbal" language, which often hinders information grasping by deaf users.
