STTR Phase I: Synchronizing Video Imagery with Wearable Sensor Data and Side-by-Side Modeling Software to Develop Healthy Habits in Children Who Participate in Sports

这个STTR第一期项目将开发Android和苹果iPhone应用程序，以便在体育活动中快速纠正不正确或危险的技术。该项目的目标是消除年轻运动员的危险、不健康行为，代之以非破坏性的技能和技术。在最简单的形式中，这项技术向玩家展示了他们自己行为的视频片段，与使用穿戴式传感器测量的头部撞击数据和基于物理的模拟相匹配，显示了在危险的撞击中大脑发生了什么。定量生物力学数据用于预测可能的功能性脑缺陷，并以适合年龄的方式呈现给用户。通过将口腔防护装置与传感器、场边视频回放技术、基于物理的大脑模拟、在线指导和观察学习相结合，教练和训练员将能够在体育活动中发生危险技术和行为时纠正它们。教练和训练员还可以向运动员展示他们自己在头部受到重大冲击后的技术视频，旁边是运动员完成相同动作但没有头部受到冲击的同步片段。因此，儿童和青少年将了解到，永远没有一个可以接受的头部接触水平。无论是适用于足球，曲棍球，长曲棍球，足球或任何数量的体育活动之一，这个教练工具将提供即时指导和自我强化的行为修正。该技术通过结合同步视频、可穿戴式冲击传感器和基于物理的模拟来识别危险事件，从而实现了体育活动中前所未有的生物力学响应分辨率，目标是获得实时技术修改，从而大大减少伤害的发生。值得注意的是，虽然传感器技术和分析方法在过去几年中取得了巨大的进步，但同步视频技术的集成将是帮助运动员了解和防止身体接触运动中发生危险的头部撞击的关键工具。移动应用程序将是一种创新的方法，以减少脑震荡和次脑震荡对头部的打击的次数和严重程度。将传感器数据、同步视频技术和基于物理的碰撞模拟整合到移动应用程序中，显示危险碰撞时大脑中发生的情况，这对体育产业来说是一种创新，并为提高运动员的体育安全提供了机会。该系统更广泛的影响是，一旦发生危险技术，就向学生和运动员展示危险技术，以及如何纠正他们的行为，这将减少运动和健身活动中严重伤害的发生，使增强健康的活动变得更加安全。

This STTR Phase I project will develop Android and Apple iPhone apps to allow for mobile-enabled, rapid correction of improper or dangerous techniques in sports activities. The project goal is to eliminate dangerous, unhealthy behaviors in young athletes and replace them with non-damaging skills and techniques. In its simplest form, the technology presents a player with a video clip of their own behavior, paired with head impact data measured using worn sensors and physics-based simulations showing what occurs in the brain during dangerous hits. The quantitative biomechanical data is used to predict possible functional brain deficits and presented to the user in an age-appropriate manner. By combining a mouth guards with sensors, sideline video replay technology, physics-based brain simulations, on-line instruction and observational learning, coaches and trainers will be able to correct dangerous techniques and behaviors in sports activity as they occur. Coaches and trainers will also be able to show players video of their own technique following a significant impact to the head next to a synchronized clip of an athlete completing the same movements, but with no head impact. As a result, children and adolescents will learn there is never an acceptable level of head contact. Whether applied to football, hockey, lacrosse, soccer or one of any number of physical activities, this coaching tool will provide immediate instruction and self-reinforcing behavior modification. The proposed technology enables unprecedented resolution of the biomechanical response during sports activities by combining synchronized video, wearable impact sensors and physics-based simulations that will identify dangerous incidents, with the goal of obtaining real time technique modification and therefore a dramatic reduction in the occurrence of injury. It is important to note that while sensor technology and analytical methods have advanced dramatically in the last several years, the integration of synchronized video technology would be a critical tool in helping players understand and prevent dangerous head impacts from occurring in contact sports. The mobile apps will be an innovative approach to reducing the number and severity of concussive and sub concussive blows to the head. Integrating sensor data, synchronized with video technology and physics-based impact simulations showing what occurs in the brain during dangerous impacts into a mobile app is innovative to the sporting industry and offers an opportunity to improve player safety in sports. The broader impact of the system is to show students and athletes dangerous techniques as soon as they occur along side of how their behavior could be modified, which will reduce the occurrence of serious injuries in sports and fitness pursuits causing health-enhancing activities to be rendered much safer.
