Using Interactive Virtual Presence to Remotely Assist Parents with Child Restraint Installations

使用交互式虚拟在线状态远程帮助家长安装儿童安全座椅 每3小时就有一名美国儿童死于汽车撞车事故。正确安装后，Car 座椅(也称为儿童约束装置)可降低婴幼儿严重受伤和死亡的风险。 坠毁了大约三倍。不幸的是，在美国公路上行驶的儿童约束中，有很大一部分 安装不正确。由训练有素的技术人员组成的网络，其中许多人隶属于安全儿童全球公司，在全球各地工作 国家通过预定的“汽车安全座椅检查”，帮助父母正确使用儿童安全座椅。 在那里，技术人员与父母合作，在他们的车辆上安装约束装置。汽车座椅检查在以下方面有效 减少儿童安全带安装中的错误。然而，由于存在障碍，这些服务的利用率严重不足 通道、调度复杂性和配置汽车座椅检查人员的资源足以满足需求。 本研究评估了交互式虚拟呈现技术(也称为交互式合并)的使用 现实)-联合和同时的远程语言和视觉交互以及接触到相同的3D刺激-TO 远程帮助父母将儿童安全座椅正确安装到他们的车辆上。如果有效，这项技术可能会 补充或更换汽车座椅检查，显著减少汽车座椅安装错误的数量 在全国范围内，并彻底改变政府、行业和非营利性机构帮助父母设置限制措施的方式。 基于对这一主题的小型初步研究，我们建议进行一项大型随机非劣势试验，以 评估父母，特别是农村地区服务不足的父母和/或代表性不足的父母 种族或少数民族背景，在与远程专家交流时安装儿童限制器 技术人员通过交互式虚拟呈现实现安全无与伦比的安装和学习 对于安装了限制器的父母，他们与现场的远程技术人员住在一起。非自卑试验是一种 随机试验，通过一种新的治疗方法(在这种情况下，互动虚拟存在来安装儿童约束装置) 与已知有效的现有治疗方法进行比较(在这种情况下，活的一对一安装 限制)，以证明新的治疗方法的效果并不比已知的现有治疗方法差 有效。为了实现我们的目标，我们将在全国7个安全儿童地点招募1476名家长，并 随机分配同意安装儿童安全带的父母，通过交互式虚拟存在或使用 现场技师。安装安全的正确性将使用客观的检查表进行评估，这两个检查表如下 安装，并在4个月后再次安装。我们的目标是证明儿童安全带安装是准确的(&gt；90% 正确)，当通过交互式虚拟存在远程进行时，此类安装不逊于 与现场专家一起安装的准确性，以及父母了解和保留有关正确信息的信息 儿童安全带装置。

Using Interactive Virtual Presence to Remotely Assist Parents with Child Restraint Installations Motor vehicle crashes cause the death of an American child every 3 hours. When installed correctly, car seats (also called “child restraints”) reduce risk of serious injury and death to infants and young children in a crash roughly threefold. Unfortunately, a very large portion of child restraints traveling on American roadways is installed incorrectly. A network of trained technicians, many affiliated with Safe Kids Worldwide, work across the country to assist parents in achieving correct use of child restraints through scheduled “car seat checks,” where technicians cooperate with parents to install restraints in their vehicles. Car seat checks are effective in reducing errors in child restraint installations. However, the services are highly underutilized due to barriers in access, scheduling complications, and resources to staff the car seat checks sufficiently to meet demand. The present study evaluates use of interactive virtual presence technology (also called interactive merged reality) – joint and simultaneous remote verbal and visual interaction and exposure to the same 3D stimuli – to remotely assist parents to install child restraints correctly into their vehicles. If effective, this technology could supplement or replace car seat checks, significantly reduce the number of errors made in car seat installations nationwide, and revolutionize how government, industry, and non-profit agencies help parents install restraints. Building from small preliminary studies on the topic, we propose a large randomized non-inferiority trial to evaluate whether parents, including especially underserved parents in rural areas and/or of underrepresented racial or ethnic minority background, who install child restraints while communicating with a remote expert technician via interactive virtual presence achieve installations and learning that are not inferior in their safety to parents who install restraints live with a remote technician on-site. Non-inferiority trials are a type of randomized trial whereby a novel treatment (in this case, interactive virtual presence to install child restraints) is compared to an existing treatment known to be effective (in this case, live one-on-one installation of restraints) to demonstrate the novel treatment does not perform inferiorly to the existing treatment known to be effective. To accomplish our goals, we will recruit 1476 parents at 7 Safe Kids locations nationwide and randomly assign consenting parents to install their child restraint either via interactive virtual presence or with a live technician. The correctness of installation safety 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 via interactive virtual presence, that such installations are not inferior to the accuracy of installation with a live on-site expert, and that parents learn and retain information about correct child restraint installation.
