Urgent information presentation using listed sign language

Abstract

This paper proposes a listed sign language system that combines written expressions in table form with sign language fragments. The system generates urgent video style messages that offer rapid, certain, and easy understanding for environments such as railway carriages. We developed a prototype of the system and conducted an evaluation experiment. The results show that the system improves the level of understanding urgent messages. Participants confirmed that the messages scored highly in terms of ease of understanding, high accuracy, rapid understanding, and sense of security. © Springer-Verlag Berlin Heidelberg 2007.
