本文介绍了一个多媒体系统的开发，以帮助盲人学习盲文音乐的乐趣和兴趣，并讨论了该系统作为一种教学工具的意义。该系统由这里开发的软件、个人计算机系统、盲文针显、盲文打印机和音响设备组成。系统的主要特点如下：1.系统的功能。在计算机CRT显示器上，通过鼠标操作，可以很容易地将墨水书写的音符和符号放在五线谱上。CRT显示器上的音符和符号在电脑上被翻译成盲文音乐，操作方便。因此，即使一个人不知道盲文音乐的复杂规则，也可以很容易地将墨迹音乐翻译成盲文音乐。这种便利导致了与翻译有关的社会福利活动的活跃。2. 在课堂上，老师能够根据学生的知识水平和目前所需的课程内容输入一个音符或一个符号。学生可以通过手指触摸来阅读翻译的盲文音乐，通过点击CRT显示器上的按钮，音乐就会显示在pin-display上。然后，课程的灵活性将是预期的。3. 对于视力有障碍的系统用户，可以通过电脑中准备的电子乐器（乐器的选择是可选的）来收听各种音乐。同时，点字音乐显示在针脚显示器上。然后，用户可以通过媒体、声音（音乐表演）和盲文音乐来学习音乐。很明显，与传统的盲文课程相比，使用该系统学习的学生能够轻松，愉快地学习盲文音乐，并且具有良好的动力。认为该系统的多媒体技术在其中起着重要的作用。

This report deals with the development of a multimedia system to aid the blind learning braille music with joy and interest, and the significance of the system as a teaching tool is discussed. The system is composed of software developed here, a personal computer system, a braille pin-display, a braille printer and audio instruments.Features of the system are as follows : 1. On a computer CRT display, ink-written musical notes and symbols are easily put on the staff notation by mouse operation. The notes and symbols on the CRT display are translated into braille music on a computer with easy operation. Therefore, even a person who does not know complicated rules about braille music is able to translate an ink-written music into braille music easily. This ease leads to the active social welfare activities concerned with the translation. 2. In a class, a teacher is able to input a musical note or a symbol according to the student's level of knowledge and the content of the lesson required at the moment. The student is able to read the translated braille music by finger touch, that was presented on a pin-display by clicking a button on the CRT display. Then, the flexibility of the lesson will be expected. 3. The system user, who has a handicap in sight, is able to listen to various music performed by electronic musical instruments (the selection of instruments is optional) prepared in the computer. Simultaneously, the braille music is presented on the pin-display. Then, the user is able to learn the music by both media, sound (musical performance) and braille music.It became clear that students learned with the system were able to learn braille music easily, pleasantly, and well motivated in comparison with a conventional lesson by a sheet in braille. It is suggested that the multimedia of this system plays an important role.
