ABSTRACT

To maintain roadway safety, officers must be trained in the Standard Field Sobriety Test (SFST) which includes a Horizontal Gaze Nystagmus (HGN) component. HGN – a repetitive jerking movement in the eyes – is an effective impairment indicator, but can be subtle and difficult to observe, particularly for inexperienced officers. Therefore, hands-on HGN learning opportunities are important for SFST training. Current HGN training often focuses on wet labs with live participants or observational videos and lectures – both with limitations. This research shows that simulation training with a virtual human is a viable HGN training approach and provides hands-on experience in various situations. Study results from the Individual Nystagmus Simulation Training Experience (INSITE) system are presented with a summary of encouraging results in confidence gains, participant feedback and other areas, particularly for newer officers. A discussion of future potential for both INSITE and virtual human training techniques for law enforcement is included.

摘要

为了保持道路安全，警员必须接受标准现场清醒测试 (SFST) 培训，其中包括水平凝视眼球震颤 (HGN) 组件。HGN——眼睛中的重复抽搐动作——是一种有效的损伤指标，但可能很微妙且难以观察，尤其是对于没有经验的警官。因此，动手 HGN 学习机会对于 SFST 培训非常重要。当前的 HGN 培训通常侧重于有现场参与者的湿实验室或观察视频和讲座——两者都有局限性。这项研究表明，使用虚拟人进行模拟训练是一种可行的 HGN 训练方法，并在各种情况下提供实践经验。个人眼球震颤模拟训练体验 (INSITE) 系统的研究结果附有令人鼓舞的信心增益结果摘要，参与者反馈和其他领域，特别是对于新官员。包括对 INSITE 和虚拟人类执法培训技术未来潜力的讨论。
