Virtual Reality by Mobile Phone: Improving Child Pedestrian Safety

移动的手机虚拟现实：改善儿童行人安全 行人受伤是儿童受伤的主要原因。有效、实用、成本效益高- 基于和理论驱动的行为干预，教幼儿过马路的技能， needed.我们的实验室探索了虚拟现实（VR）作为一种手段，教儿童行人安全技能， 有几个原因，包括：（a）它为儿童提供了反复的无人监督的练习， 伤害的风险，（B）它为儿童提供关于穿越成功或失败的自动反馈，（c）它可以定制 （d）它提供了一个有吸引力和有趣的培训环境，以及（e）最近给予 随着技术的进步，它提供了利用移动的电话技术进行广泛传播的潜力。先前 研究显示，虚拟现实是一种有效的行人安全训练工具。目前的建议扩大了以前的建议， 在两个关键方面的发现。首先，它将评估使用移动的手机和 Google Cardboard平台，2014年发布的技术，使标准的移动的手机能够用作 沉浸式虚拟现实传输系统。其次，它将克服以往研究的局限性 这表明孩子们在VR中进行了六次30分钟的训练后学会了一些步行技能， 掌握成人水平的步行技能。我们将实施一项随机非劣效性试验， 7-8岁儿童组（总N = 498）。所有参与者将完成基线、干预后和6- 一个月的行人安全跟进评估和最多二十五个30分钟的行人安全训练 直到他们达到成年人的功能水平。一半的孩子将被随机分配到谷歌培训 Cardboard和另一半在现有的半沉浸式实验室VR中。将评估主要结局 使用ANCOVA模型。

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.
