Sign Tutor

In this project, we have conducted research on the analysis of Turkish Sign Language and developed educational tools for teaching Turkish Sign Language, with the support of the Scientific and Technological Research Council of Turkey. Turkish Sign Language (TID) is a visual language, used by the hearing impaired, which consists of hand gestures and facial expressions. The study of sign language is a currently interesting research field both by computer vision researchers and linguists. Beyond the research interest, the development of educational tools for teaching sign language has benefits to the general community. The aim of this project is the development of educational tools for sign language while doing research on sign analysis and recognition from videos. With this purpose, we have worked in five different areas:

  • Development of Turkish Sign language databases for research and education
  • One of the databases collected has been used for a website and stand-alone application program for a TID sign dictionary
  • Research on analysis of sign language from videos and the development of a prototype of an interactive sign tutor
  • The development of Signiary, a Sign Dictionary which uses the Turkish Radio Television’s news for the hearing impaired
  • Research on distributed sign language recognition in a multi-agent environment.

The output of the project is in the form of theses, reports, journal papers and conference papers. In addition, we have produced databases and demonstrator programs.
