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.

拟议研究的目标是设计、开发、测试和演示临床使用 用于视野测试的头戴式仪器。这种重量轻、成本低的设备将是一个商业上可行的、基于虚拟现实显示技术的综合视野测试平台。 视野检查是眼科的基本诊断工具之一。它在青光眼的检测中特别有用，随着新出现的测试程序的引入，测试的灵敏度不断提高。所提出的设备将用于测试视野性能、视力和色觉。它将为患者提供前所未有的头部和身体运动自由度，从而最大限度地减少甚至消除传统视野测试系统常见的压力和疲劳。灵活的计算机化平台和最先进的显示技术将使系统能够轻松重新配置，以适应新兴和未来的测试场景。视线跟踪设备的结合提高了测试的可靠性和准确性。 第一阶段工作的目标是设计和构建头戴式视野仪原型。
