INTELLIGENT ELECTRONIC MAGNIFIER LOW-VISION PATIENTS

一种新型微机化“智能”系统的原型 数字文档放大镜(DDM)将是 作为低视力辅助器而建造的。DDM使用高电平 分辨率扫描仪可提供类似CCTV的轻松文档图像 采集和图像质量，再加上 以前基于计算机的放大图像处理 放大镜，以及提供低视觉“用户友好”的特点 以前的任何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。 预计专用的独立便携版本 DDM可以根据第二阶段提案进行设计，可以 以不到2,500美元的最终用户成本生产。

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.
