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.

一个新的基于微型计算机的“智能”原型 放大镜，数字文档放大镜（DDM）， 被构造成用作低视力辅助器。 DDM使用高 分辨率扫描仪，提供类似CCTV的轻松文档图像 采集和图像质量，以及方便 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”的功能 以前的任何放大系统都没有提供。 该系统 完全由轨迹球、鼠标或操纵杆控制，包括 用户可通过下拉菜单修改参数。 预计专用的独立便携版 根据第二阶段的建议，可以设计出这样的分布式防御系统， 最终用户成本低于2500美元。
