Development and dissemination of USB adaptive devices for children with physical disabilities

在这个项目的第一年，作者研究了最优的USB（通用串行总线）IC控制器，用于身体残疾儿童的自适应设备，以有效地使用键盘导航。目的的观点如下：1)控制器的特点和价格，2)开发工具的功能和价格，3)耐用性和普及性。选用美国国家半导体公司生产的USBN9602芯片，开发了USB自适应器件的软件程序。在该项目的第二年，作者开发了Wing-USB，这是一种为身体残疾儿童设计的USB自适应设备。该器件配备USBN9602和PIC16F877，有8个输入端口，为8个操作开关准备。Wing-USB根据键盘导航规范生成专用线。进行了实地研究。测试结果表明，这些设备完全可以在最新的操作系统上运行，比如Windows 98和Macintosh。讨论了进一步的影响。

For the first year of this project, the authors investigated optimal USB (Universal Serial Bus) IC controllers for the adaptive devices for children with physical disabilities to use keyboard navigation effectively. The points of view for the purpose are as follows : 1) the characteristics and prices of the controllers, 2) functions of development tools and prices, 3) durability and popularity. The authors choose USBN9602 manufactured by National Semiconductor Inc. and developed software programs for USB adaptive devices.For the second year of the project, the authors developed Wing-USB, USB adaptive devices for children with physical disabilities. The device, equipped with USBN9602 and PIC16F877, has eight input ports prepared for eight operating switches. Wing-USB generates special cords according to keyboard navigation specification. Field studies were conducted. The results indicated that the devices worked fully on the latest OS, such as Windows 98 and Macintosh. Farther implications were discussed.
