In-Home Reading-Eye-Movement Training System

鉴于人口迅速老化，加上与年龄有关的眼疾的发病率， 在未来几十年中，视力低下的人数预计将急剧增加。 中央视力丧失的患者不能再使用他们的中央凹，偏心视网膜必须 用于执行视觉任务。由于周边视网膜的感觉能力降低， 改变的视觉行为，日常视觉任务的表现，如阅读， 非常困难。个人独立性、自信心和隐私可能会受到损害， 因为个人可能不得不依赖他人来阅读他们的私人信件。中 低视力患者最重要的目标是保持/获得阅读技能。此前我们 开发并验证了一个有效的临床培训计划，以提高阅读速度， 低视力的人。本项目的主要创新之处在于开发了 一种用于训练眼动控制以提高个人阅读速度的家庭平台 视力受损的人个人电脑技术目前可用于制作界面 方便视障人士使用，包括英特尔实感3D摄像头;触摸屏;以及 可靠的语音控制。此外，新的眼动监测硬件（例如，Tobii EyeX）是 坚固耐用，价格实惠。我们建议开发一种家庭阅读眼动训练 系统互联网连接将提供对培训的日常监测。该项目有四个 具体目标：（1）在第一个月，我们将开发和完善的PC硬件与眼睛 跟踪.这将包括确定硬件的各个方面，使其在家庭中有用;（2）在 在未来三个月内，我们会开发一套可供家居使用的界面软件;（3）在 在接下来的两个月里，我们将与8名视障人士测试用户界面，并使用 他们的反馈，使系统可用于家庭培训;和（4）在最后六个月， 我们将在有20名视力受损参与者的家庭中进行概念验证测试， 可用性、可接受性和有效性。统计方法将使我们能够解决以下问题 可用性两个问题：至少80%的视障参与者是否能够至少 90%的训练成功，并且在家进行眼动训练效果显著 至少70%完成培训的受试者的阅读能力得到提高？

Given the rapidly aging population and the incidence of age related eye diseases, the number of individuals with low vision is expected to increase dramatically in the next decades. Patients with central vision loss can no longer use their foveas and eccentric retina must be used to perform visual tasks. Since the peripheral retina has reduced sensory capabilities and altered oculomotor behavior, performance of everyday visual tasks, such as reading, are extremely difficult. Personal independence, self-assurance, and privacy may be compromised, as individuals may have to rely on others to read their personal correspondence. Among the most important goals of low-vision patients is maintaining/gaining reading skills. Previously, we have developed and validated an effective clinical training program to increase reading speed in individuals with low vision. The major innovation of the current project is the development of an in-home platform for training eye movement control to improve reading speed in individuals with vision impairment. Personal computer technology is currently available to make interfaces accessible to visually impaired people, including Intel RealSense 3D camera; touch screens; and reliable voice control. In addition, new eye movement monitoring hardware (e.g., Tobii EyeX) is robust and affordable. We propose to develop an in-home reading-eye-movement training system. Internet connection will provide daily monitoring of training. The project has four specific goals: (1) In the first month, we will develop and refine the hardware of the PC with eye tracking. This will include determining aspects of hardware to make it useful in home; (2) In the next three months, we will develop the software for an accessible in-home interface; (3) In the next two months, we will test the user interface with 8 visually impaired participants and use their feedback to make the system usable for in-home training; and (4) In the final six months, we will conduct proof of concept testing in homes with 20 visual impaired participants to assess usability, acceptance, and efficacy. Statistical methods will allow us to address the following usability two questions: Can at least 80% of the visually impaired participants perform at least 90% of the training successfully, and does the in-home eye movement training significantly improve the reading ability in at least 70% of the subjects that completed the training?
