Abstract
The SignWriting system (developed at the Center
for Sutton Movement Writing, Ca., USA), is a writing system for
deaf sign languages. In SignWriting, signs are represented as
figures made up of graphic symbols, each symbol schematically
representing an important aspect of the sign gestures: hand configurations,
hand and finger movements, contacts, facial expressions, etc. SWML (SignWriting Markup
Language) is an XML-based format that we are developing for the
storage and processing of SignWriting texts and dictionaries,
allowing the interoperability of SignWriting savvy applications
and promoting web accessibility to deaf people in their own natural
languages. SSS.svg is a standard representation of the whole SignWriting symbol
sequence as SVG symbols, allowing the flexible rendering of signs
written in SignWriting as graphical elements in web pages. This
paper initially presents the SignWriting system and its importance
as a deaf sign language writing system and considers why supporting
written sign languages on the web should be considered both as
an accessibility issue and as a problem of multiculturalism and
multi-linguality in the web. Then, the paper reports on the state
of the work being done on the development of SWML (current status: version 1.0 - draft 2) and states preliminary
ideas for the organization and searching of sign language text
database. Finally, the paper shows the prospects for and the
current status of the development of a SignWriting-based web
application (SW-WebMail)
using SWML and SSS.svg to render sign languages. |
