项目摘要

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：提高儿童行人安全行人受伤是儿童受伤的主要原因。有效、实用且具有成本效益的经验- 基于理论驱动的行为干预来教授幼儿过马路技能需要。我们的实验室探索了虚拟现实（VR）作为教授儿童行人安全技能的一种手段有几个原因，包括：(a) 它让儿童在没有监督的情况下重复过人行横道的练习受伤的风险，（b）它向儿童提供有关穿越成功或失败的自动反馈，（c）它可以定制儿童技能水平：(d) 它提供了一个有吸引力且有趣的训练环境，并且 (e) 最近给予技术进步，它提供了使用移动电话技术广泛传播的潜力。以前的研究表明VR是一种有效的行人安全培训工具。本提案扩展了之前的建议两个关键方面的发现。首先，它将评估使用手机交付行人 VR 以及 Google Cardboard 平台，2014 年发布的技术，使标准手机能够用作沉浸式虚拟现实交付系统。其次，它将克服以往研究的局限性建议孩子们在 VR 中进行六次 30 分钟的训练后学会了一些行人技能，但尚未学会掌握成人水平的行人技能。我们将实施一项随机非劣效性试验，其中有两个同等规模的患者 7-8 岁儿童组（总数 = 498）。所有参与者将完成基线、干预后和 6- 每月的行人安全跟踪评估以及最多 25 次 30 分钟的行人安全培训进行试验，直到达到成人的功能水平。一半的孩子将被随机分配到谷歌接受训练纸板和另一半在现有的半沉浸式 VR 实验室中。将评估主要结果使用ANCOVA模型。
