The goal of the proposed research is to design, develop, test and demonstrate clinical use of a head-mounted apparatus for visual field test. This low-weight, low-cost device will be a commercially viable, comprehensive visual field test platform based on virtual reality display technology. The visual field test is one of the basic diagnostic tools of ophthalmology. It is especially useful in the detection of glaucoma, where sensitivity of the test has been increasing with introduction of newly emerging test procedures. The proposed device will find a use in testing of visual field performance, visual acuity, and color vision. It will allow the patient an unprecedented freedom of movement of the head and body, thus minimizing or even eliminating the stress and fatigue common with the conventional visual field testing systems. Flexible, computerized platform, and state-of-the art display technology will enable easy re-configuration of the system to accommodate emerging and future test scenarios. Incorporation of gaze tracking device increases test reliability and accuracy. The goal of Phase I work is to design and construct a prototype of head-mounted visual field apparatus.

拟议研究的目的是设计，开发，测试和证明 视觉现场测试的头部安装设备。基于虚拟现实显示技术，这种低重量，低成本的设备将是一个商业上可行的，全面的视野测试平台。 视野测试是眼科的基本诊断工具之一。它在检测青光眼的检测中特别有用，在引入新出现的测试程序随着测试的敏感性增加。所提出的设备将在测试视野性能，视力和色觉来测试中使用。这将使患者具有前所未有的头部和身体运动自由，从而最大程度地减少甚至消除了与常规的视野测试系统常见的压力和疲劳。灵活的，计算机化的平台和最先进的展示技术将使系统轻松地重新配置，以适应新兴和未来的测试场景。凝视跟踪设备的合并提高了测试可靠性和准确性。 第一阶段工作的目的是设计和构建头部安装的视野设备的原型。
