In this paper, we discuss the number of images and their contents required for a good remote sign language interpretation service. Our approach uses dual-video transmission which gives interpreters full view of the remote place. For example, the interpreter can see the face of a hearing speaker giving a presentation and the faces of the deaf audience at the same time. Evaluation experiments were conducted for two kinds of scenes, a conversation scene and a lecture scene. The experimental system of remote sign language interpretation service and subjective evaluations are described. A questionnaire survey has shown dual-video transmission to be highly practical for remote sign language interpretation services.
