Sign language communication via videotelephone has demanding visual quality requirements. In order to optimise video coding for sign language it is necessary to quantify the importance of areas of the video scene. Eye movements of deaf users are tracked whilst watching a sign language video sequence. The results indicate that the gaze tends to concentrate on the face region with occasional excursions (saccades). The implications of these results for prioritised coding of sign language video sequences are discussed.
