  • Patent number: 6477239
    Abstract: A sign language telephone device is offered which enables an aurally handicapped person who uses the sign language to converse with a normal person at a distant place who does not know the sign language. The sign language telephone device is placed on the side of the aurally handicapped person, and hand gestures of the sign language inputted from a sign language input means are recognized as the sign language, and the recognized sign language is translated to Japanese. The translated Japanese word train is converted to synthesized voices and it is transmitted to a videophone on the side of a normal person. The voices from the videophone are recognized, and the recognized Japanese is translated to the sign language to generate sign language animations and they are displayed on the screen of a TV set on the side of the aurally handicapped person.

  • Patent number: 5990878
    Abstract: A sign language editing apparatus includes a glove-type sensor for converting movement of fingers in the sign language into an electrical signal to produce time series data of sign language words, a sign language word data editing device for adding predetermined additional data to the time series data inputted from the glove-type sensor to process the time series data, a sign language word dictionary for storing the time series data of sign language words processed by the sign language word data editing device, a sign language sentence data editing device for reading out the time series data of sign language words stored in the sign language word dictionary in accordance with the predetermined characters inputted from the input unit and adding predetermined additional information to the time series data of sign language words to produce time series data of sign language sentence, a sign language animation synthesizing device inputted with the time series data of sign language sentence produced by the sign lan

  • Patent number: 5953693
    Abstract: A sign language interpretation apparatus for performing sign language recognition and sign language generation generates easily read sign language computer graphics (CG) animation by preparing sign language word CG patterns on the basis of actual motion of the hand through the use of a glove type sensor to generate natural sign language CG animation, and by applying correction to the sign language word CG patterns. Further, in the sign language interpretation apparatus, results of translation of inputted sign language or voice language are confirmed and modified easily by the individual input persons, whereby results of translation of the inputted sign language or voice language are displayed in a combined form desired by the user to realize smooth communication. Also, candidates obtained as a result of translation are all displayed and can be selected easily by the input person with a device such as a mouse.

  • Patent number: 5734923
    Abstract: An information output apparatus which outputs guide information in combination with image, text, voice and sign-language so that hearing impaired, handicapped people can easily recognize the guide information. The sign-language is automatically generated by computer graphics on the basis of text information inputted to the apparatus. A user can edit the generated sign-language. When it is desired to perform a generating operation over additional sign-language information, a transitional picture is automatically inserted between the sign-language words to provide clear discrimination between the words. The inserting manner can be specified by the user.
