After a brief review of the origin and present state of sign-language as the principal means of communication among the deeply deaf, the main existing proposals for enabling telecommunications for this sub-community of handicapees are reviewed. Arising from this analysis, a new system is proposed, based on the transmission of a severely simplified image sequence, using extraction of contours to obtain the effect of a real-time animated cartoon drawn from the actual scene. Some preliminary experimental results are presented, together with a discussion of the future stages of the investigation. An appendix describes a contour extraction algorithm applied in this work.
