DESCRIPTION (provided by applicant): Brain injury frequently results in cognitive impairment reducing an individual?s ability to judge driving situations accurately. Rehabilitation professionals use on-road tests to determine if an individual is safe to drive, but these tests are typically performed under calm conditions and offer little information on the individual?s responses to typical, real-life driving challenges. STISIM is a relatively low-cost, high performance, customizable driving simulator based upon standard desktop computer technology. The purpose of this Phase II STTR project is to determine if STISIM can be adapted to the clinical rehabilitation market for use by rehabilitation driving professionals and their client with cognitive impairments. Proof of concept was demonstrated in Phase I which resulted in the creation of a driving scenario that offers increasingly complex driving challenges as the route proceeds, the development of data collection and analysis procedures to quantitatively evaluate driving performance and the pilot testing of the scenario, data collection and processing methods using five subjects with mild cognitive impairments and five age-matched control subjects with no impairments. The result demonstrated that the simulator was capable of identifying significant driving differences between the two groups. In Phase II, impairments to the hardware and software of STISIM will be implemented. A multi-center clinical study will be conducted to evaluate test-retest reliability, discriminant validity and concurrent validity of STISIM when using subjects with cognitive impairments. In addition, an ease-of-use study and a self-awareness pilot study will be conducted. At the end of Phase II, the applicant company (STI) will be prepared to move into a commercialization phase to bring the STISIM simulator into the rehabilitation market.

描述（由申请人提供）：脑损伤经常导致 认知障碍会降低个体的认知能力吗判断驾驶的能力 情况准确。康复专业人员使用道路测试， 确定一个人是否可以安全驾驶，但这些测试通常是 在平静的条件下进行，并提供关于 个人？的反应典型的，现实生活中的驾驶挑战。STISIM是一个 相对低成本、高性能、可定制的驾驶模拟器 在标准的台式电脑技术上。本阶段II STTR的目的 项目是确定STISIM是否适用于临床康复 市场使用的康复驾驶专业人员和他们的客户与 认知障碍 概念验证在第一阶段得到了证明， 驾驶场景提供了越来越复杂的驾驶挑战， 路线收益，开发数据收集和分析程序， 定量评估驾驶性能和试点测试的 使用五名轻度抑郁症受试者的情景、数据收集和处理方法 认知障碍和五个年龄匹配的对照组， 损伤结果表明，该模拟器能够 识别两组之间的显著驱动差异。 在第二阶段，将对STISIM的硬件和软件的损害进行评估。 切实贯彻将进行一项多中心临床研究， 重测信度、区分效度和同时效度 使用认知障碍受试者时的STISIM。此外， 将进行易用性研究和自我意识试点研究。在 第二阶段结束后，申请公司（STI）将准备进入一个 商业化阶段，将STISIM模拟器引入康复 市场
