Evaluation tests of sign communication with delayed video are reported and the effect of delay on the communication is discussed. The authors constructed the delayed sign dialogue experimental system. Five kinds of tasks were assigned to deaf subjects and videos of performing the task with various delay times were recorded. By analyzing the data, sign communications was found to be more tolerant of the delay time than voice communication.
