Virtual Reality by Mobile Phone: Improving Child Pedestrian Safety Pedestrian injuries are a leading cause of pediatric injury. Effective, practical, and cost-efficient empirically- based and theoretically-driven behavioral interventions to teach young children street-crossing skills are needed. Our laboratory has explored virtual reality (VR) as a means to teach child pedestrian safety skills for several reasons, including: (a) it offers children repeated unsupervised practice in pedestrian crossings without risk of injury, (b) it provides automated feedback to children on crossing success or failure, (c) it can be tailored to child skill levels: (d) it offers an appealing and fun training environment, and (e) most recently given technological advances, it offers potential for broad dissemination using mobile phone technology. Previous work indicated VR was an effective pedestrian safety training tool. The present proposal extends previous findings in two critical ways. First, it will evaluate delivery of a pedestrian VR using a mobile phone and the Google Cardboard platform, technology released in 2014 that enables a standard mobile phone to be used as an immersive virtual reality delivery system. Second, it will overcome the limitation of previous research suggesting children learned some pedestrian skills after six 30-minute training sessions in a VR but did not yet master adult-level pedestrian skills. We will implement a randomized non-inferiority trial with two equal-sized groups of children ages 7-8 (total N = 498). All participants will complete baseline, post-intervention, and 6- month follow-up assessments of pedestrian safety and up to twenty-five 30-minute pedestrian safety training trials until they reach adult levels of functioning. Half the children will be randomly assigned to train in Google Cardboard and the other half in an existing semi-immersive laboratory VR. Primary outcomes will be assessed using ANCOVA models.

手机虚拟现实：改善儿童行人安全 行人伤害是小儿损伤的主要原因。有效，实用且具有成本效益的经验 以理论和理论上驱动的行为干预措施来教幼儿街头交叉技能 需要。我们的实验室探索了虚拟现实（VR），以教导儿童行人安全技能 几个原因，包括：（a）它为行人穿越中反复的无监督练习提供了 受伤的风险，（b）它为儿童交叉成功或失败提供自动反馈，（c）可以量身定制 到儿童技能水平：（d）它提供了一个吸引人且有趣的培训环境，并且（e）最近给出了 技术进步，它提供了使用手机技术进行广泛传播的潜力。以前的 工作表明VR是一种有效的行人安全培训工具。目前的提议扩展了以前的 发现有两种关键方式。首先，它将使用手机评估行人VR的交付 Google Cardboard平台，2014年发布的技术，可将标准手机用作用作 沉浸式虚拟现实交付系统。其次，它将克服先前研究的局限性 建议孩子在VR六个30分钟的培训课程后学习了一些行人技能，但还没有 硕士成人级行人技能。我们将实施一个随机的非效率试验 7-8岁的儿童组（总n = 498）。所有参与者将完成基线，干预后和6-- 行人安全和最多二十五30分钟的行人安全培训评估月的随访评估 试验直到达到成人的功能水平。一半的孩子将被随机分配到Google中训练 纸板和另一半在现有的半脱落实验室VR中。将评估主要结果 使用ANCOVA模型。
