Project Summary Visionize has developed a sophisticated wearable state of the art low vision aid by reprogramming a readily available low cost off the shelf Virtual Reality system. The device operates in three main modes: 1) The patient views the real world with adjustable magnification power and area within the overall scene. 2) The patient also has access to the full complement of digital media ranging from digital news and email to digital streaming media like Netflix and you tube. 3) The clinician has diagnostic capability via remote access to patient display and responses. The device is built from the Samsung Galaxy S7 phone, one of the most advanced on the market, inserted into a Samsung Gear VR headset. On the phone display the low vision user sees an enhanced version of the visual world tuned to specific visual deficit. The goal of this project is to refine the function of the device to a level where it can be successfully deployed to a population of test patients at the Johns Hopkins low vision clinic. Then the device will be further refined and enhanced through feedback from the patient population. The end goal is to develop a low vision aid with superior performance that can be distributed to a large low vision population worldwide at an affordable price.

项目摘要 Visionize开发了一种复杂的 可佩戴的最先进的低视力辅助器， 重新编程一个现成的低成本 虚拟现实系统。的 该装置以三种主要模式操作：1） 患者通过可调节的方式观察真实的世界 放大率和面积内 整体场景。2)病人也可以 数字媒体的全面补充 从数字新闻和电子邮件到数字 像Netflix和YouTube这样的流媒体第三章 临床医生具有诊断能力， 远程访问患者显示器， 应答该设备是建立在三星Galaxy S7手机，其中一个最先进的 市场，插入到三星齿轮VR耳机.在手机显示屏上， 看到的是一个针对特定视觉缺陷的增强版视觉世界。这个目标 该项目的目的是将设备的功能细化到可以成功部署到 约翰霍普金斯低视力诊所的测试患者群体。那么该装置将进一步 通过患者群体的反馈进行改进和提高。最终目标是发展 具有上级性能的低视力辅助器，可分发给大量低视力人群 在全球范围内以合理的价格。
