项目摘要

As a part of study on self-learning system for improving language ability of the hearing-impaired, an electronic sign language dictionary system has been developed. The system is planned for use in analyzing the detail of sign gesture in order to refine the descriptions, as well as for use in self-learning of sign language by beginners.The sign language vocabulary used in this dictionary is a set of 950 sign words which are highly frequent in daily use in Japanese sign language. Each of the selected sign words is labeled with a new descriptive symbol for the hand shape, as well as a description of the position and movement of the hands, and phonetic and orthographic descriptions of corresponding Japanese. Video pictures of these words, signed by a female native signer, are recorded on a lazer disc. These recorded video pictures are linked to a computer controlled laser disc player, so that the corresponding video pictures in the sign language vocabulary can be retrieved instantaneously from any of the descriptive items in the database.The descriptive symbol system for the hand shape proposed here is based on the anatomical structure modelling of finger action, and consists of a combination of primary features of the hand shapes, the mutual relationships among the index, middle, ring and little fingers, and features of the thumb.It is also planned to introduce syntactic information to the database to coordinate each word with other words. In addition to the concatenation between the gestures for successive words, the organization of phase and sentence structure, caused by prosodic features such as the time duration of the words, pause, and facial expression ib to be utilized in the next stage.

作为提高听障者语言能力的自主学习系统研究的一部分，我们开发了一个电子手语词典系统。该系统的目的是对手势的细节进行分析，使其更加精细化，并用于初学者的手语自学。本词典中使用的手语词汇是日语手语中日常使用频率很高的950个手语词汇。每个选定的符号词都标有手形的新描述符号，以及手的位置和运动的描述，以及相应日语的语音和拼写描述。这些文字的视频图片，由一位女性土著签名者签名，被记录在激光光盘上。本文提出的手形描述符号系统是以手指动作的解剖结构模型为基础，由手形的主要特征组合而成，它包括：手形的基本特征、手形的基本特征、手形食指、中指、无名指和小指之间的相互关系，以及拇指的特征。还计划在数据库中引入句法信息，以使每个单词与其他单词相协调。除了连续单词的手势之间的连接之外，由韵律特征（诸如单词的持续时间、停顿和面部表情）引起的短语和句子结构的组织将在下一阶段中被利用。
