机动车碰撞是造成美国1-5岁儿童死亡的第三大原因。如果安装正确，儿童约束装置（汽车座椅）可以降低严重伤害和死亡的风险。然而，大多数约束装置安装不正确。目前正确安装汽车座椅的黄金标准是系统的汽车座椅检查，由认证的技术人员帮助父母，但由于访问、调度和资源方面的障碍，汽车座椅检查的使用率非常低。目前的研究方案描述了评估使用交互式虚拟存在技术（交互式合并现实）的计划——联合、同步远程口头和视觉交互以及暴露在相同的3D刺激下——以帮助远程定位的父母安装儿童约束装置。如果有效，这项技术可以补充或取代面对面的检查，并彻底改变政府、行业和非营利组织帮助父母正确安装儿童约束装置的方式。在初步研究的基础上，我们提出了一项随机的非劣效性试验，以评估通过智能手机上的交互式虚拟存在与远程专家技术人员交流时安装儿童约束装置的父母是否安装了儿童约束装置，并且在安全方面的学习能力并不逊于与现场技术人员安装约束装置的父母。我们将在美国7个地点随机分配1476名护理人员，通过互动虚拟在场或现场技术人员安装儿童约束装置。安装后和4个月后，将使用客观检查清单评估安装的正确性。我们的目标是证明儿童约束装置在远程安装时是准确的（bbbb90 %正确率），这种安装不低于现场专家的安装准确性，父母学习并保留有关儿童约束装置安装的信息。
Motor vehicle crashes are the third-leading cause of death to American children aged 1–5 years. When installed correctly, child restraints (car seats) reduce risk of serious injury and death. However, most restraints are installed incorrectly. The current gold standard for correct installation is systematic car seat checks, where certified technicians help parents, but car seat checks are highly underused due to barriers in access, scheduling and resources. The present study protocol describes plans to evaluate use of interactive virtual presence technology (interactive merged reality)—joint, simultaneous remote verbal and visual interaction and exposure to the same 3D stimuli—to assist remotely located parents installing child restraints. If effective, this technology could supplement or replace in-person checks and revolutionise how government, industry and non-profits help parents install child restraints properly. Building from preliminary studies, we propose a randomised non-inferiority trial to evaluate whether parents who install child restraints while communicating with remote expert technicians via interactive virtual presence on their smartphones achieve installations and learning not inferior in safety to parents who install restraints with on-site technicians. We will randomly assign 1476 caregivers at 7 US sites to install child restraints either via interactive virtual presence or live technicians. Correctness of installation will be assessed using objective checklists, both following installation and again 4 months later. We aim to demonstrate that child restraint installation is accurate (>90% correct) when conducted remotely, that such installations are not inferior to installation accuracy with live experts and that parents learn and retain information about child restraint installation.
