There are a lot of equipment such as the video screen, the sign language interpreter images, and key word PC screens within the range in hearing impaired student's view. Result of the questionnaire from a free description in the hearing impaired student after experiments shows :・It is important that all screens enter in view at the same time.・ The difference of the depth between presentation information is not so anxious.The sign language interpreter of remoteness also necessary to see a lot of screens, for example hearing impaired students image, lecture room image, keywords, etc. at the same time while reading and expressing sign language. Result of questionnaire shows :・To use the chroma-key synthesis easily from two screens arranged at the top and bottom.That is, the presentation method with a little glance movement is preferable in the sign language expression and reading.Experiment to the academic conference was tried basing these results. The image presented to the sign language interpreter was made only a plasma display 50 inch one screen in the experiment. All images, the hearing impaired image, the speaker image, the presentation slide, and the key word, were synthesized in one screen.
