Sign-Language Subtitling

Wednesday, 3 August, 5:15 - 5:55 pm
Room 502B

A new method of sign-language subtitling for motion pictures aimed at deaf children who cannot read English yet and can communicate only via signs. The method is based on the recently introduced concept of "semantroid" (an animated 3D avatar limited to head and hands) and on implementation of a new scrolling technique that allows for concurrent display of four subtitling windows at the bottom of the screen.

The highlights of the presentation are:
  • The semantroid model optimized for maximum visibility and readability of face and hands configurations
  • Advantages and disadvantages of the semantroid model versus human signers and full-body avatars
  • Difficulties with traditional sign-language subtitling methods
  • The new scrolling subtitling technique applied to an educational video of a chemistry experiment.
  • Report on testing and evaluation of the method.
