This Small Business Innovation Research Phase I project from Star Mountain, Inc.(which recently bought the Systems Effectiveness Division of Essex Corporation) sets out to develop a portable dynamic visual acuity (DVA) test system. DVA has been described as a global measure that reflects the efficiency of the entire oculomotor system. When compared to measures of static acuity, measures of dynamic resolution for moving targets have shown strong relationships with stimulus and organismic variables and many applied tasks in which dynamic viewing is involved (e.g., driving, flying, sports, etc.). Unfortunately, one cannot purchase a DVA instrument 'off the shelf.` This effort will examine the feasibility of development and initial normative testing of a low-cost, portable DVA apparatus that incorporates available computer and laser technology for the controlled presentation of moving targets. The requisite flexibility and reliability that are needed for its practical use in both applied and research settings are emphasized. DVA changes have been demonstrated in such diverse areas as driving assessment among the elderly, the consequences of alcohol impairment in dynamic settings, and the implications of pathological eye-movement conditions associated with many neurological disorders. In Phase I, the Star Mountain project team will also link performance on the portable device with the traditional laboratory devices for which current predictive validities toward real world settings are available. The next phase of the research will continue development of the device, establish norms, and empirically demonstrate validity of the device. The human factors science and technology communities the interest in and need for a DVA test system keen. Thus sales to military, university and industrial vision laboratories for use in basic research and advanced development studies will be made as soon as a prototype is available (end of Phase I) The larger market would take a little longer to develop and would include incorporation of DVA into driver's license renewal testing, selection for various occupations (pilot, etc.), and identification of functional loss in the elderly.

Star Mountain, Inc.（最近收购了 Essex Corporation 的系统有效性部门）的这一小型企业创新研究第一阶段项目旨在开发便携式动态视力 (DVA) 测试系统。 DVA 被描述为反映整个动眼神经系统效率的全球性衡量标准。 与静态敏锐度的测量相比，移动目标的动态分辨率的测量显示出与刺激和有机变量以及涉及动态观看的许多应用任务（例如驾驶、飞行、运动等）的密切关系。不幸的是，人们无法购买“现成的”DVA 仪器。这项工作将检验低成本、便携式 DVA 仪器的开发和初步规范测试的可行性，该仪器结合了可用的计算机和激光技术来控制移动目标的呈现。 强调了其在应用和研究环境中实际使用所需的必要灵活性和可靠性。 DVA 的变化已在多种领域得到证实，例如老年人的驾驶评估、动态环境中酒精损伤的后果以及与许多神经系统疾病相关的病理性眼球运动状况的影响。 在第一阶段，星山项目团队还将把便携式设备的性能与传统实验室设备联系起来，这些设备当前对现实世界设置的预测有效性是可用的。 下一阶段的研究将继续开发该设备，建立规范，并凭经验证明该设备的有效性。 人因科学和技术界对 DVA 测试系统的兴趣和需求非常浓厚。 因此，一旦原型可用（第一阶段结束），将立即向军事、大学和工业视觉实验室销售，用于基础研究和高级开发研究。更大的市场将需要更长的时间来开发，并将包括将 DVA 纳入驾驶执照更新测试、各种职业（飞行员等）的选择以及老年人功能丧失的识别。
