Abstract
Recently it has become possible for the hearing impaired in remote locations to communicate via sign language using video phones and video conferencing systems. In the future, it appears likely that these technlogies will make it possible to provide remote sign language interpretation services. In actually attempting visual communication for the hearing impaired, however, critical problems must be take in account, besides the issue of video quality, picture quality and refresh rate, that is currently being examined. with our classes we are conducting experiments of remote sign language interpretation, and show that the sub window is effective for the remote sign language interpreting.
