Abstract
Using the technologies of image processing, spatial/temporal resolution reduction and picture coding, a terminal has been designed and constructed which allows the transmission of deaf sign language over low bandwidth telephone lines in real time. Using the hardware, six deaf subjects have evaluated this system. A series of psycho-physical experiments were conducted to determine the minimum image quality required to convey meaning in hand-sign language as used by the deaf.
