A prototype of a new microcomputer-based "intelligent" magnifier, the Digital Document Magnifier (DDM), will be constructed for use as a low vision aid. The DDM uses a high resolution scanner to provide CCTV-like ease of document image acquisition and image quality, together with the convenience of magnified image manipulation of previous computer-based magnifiers, as well as offering low vision "user friendly" features not provided on any previous magnification system. The system is controlled entirely by a trackball, mouse or joystick, including parameter modification by the user via pull down menu. It is anticipated that a dedicated standalone portable version of the DDM could be designed, under a Phase II proposal, that could be produced at an end user cost of less than $2,500.

基于微电脑的新型“智能”原型 放大镜，数字文档放大镜（DDM），将 专为低视力辅助设备而设计。 DDM采用高 分辨率扫描仪可提供像闭路电视一样轻松的文档图像 采集和图像质量，以及便利性 以前基于计算机的放大图像处理 放大镜，以及提供低视力“用户友好”功能 任何以前的放大系统都没有提供。 该系统是 完全由轨迹球、鼠标或操纵杆控制，包括 用户通过下拉菜单修改参数。 预计将有一个专用的独立便携式版本 根据第二阶段提案，DDM 的设计可以 最终用户的生产成本低于 2,500 美元。
