Dear EPSRC staff: I appreciate you may have some difficulty fitting this project into a particular research area, because it is interdisciplinary. It is at the interface of structural engineering and movement science with implications for medical rehabilitation and healthy ageing.The research questions the project is trying to address/the objectives of the project:What are the balance and control methods used by humans standing or walking on moving surfaces.This topic is particularly important because balance control can be compromised in people who have suffered strokes, have diseases such as Parkinsons, are recovering from knee/hip replacement or are simply aging. Such people are already less stable while standing and are more likely to experience problems where the floor is moving, which can occur not just in air, rail, road of water transport but on structures such as vertically lively floors, footbridges or grandstands and swaying footbridges or even tall buildings. Tolerance to such motion is poorly understand even forthe young and able-bodied, and there is no information on the factors that reduce such tolerance.The approach that will be taken to answer these questions (what the student will actually be doing):The research will explore the mechanisms of balance and stability for different types of floor motion (roll, pitch, heave and sway) at different levels and frequencies representingreal situations in transport and on structures. It will also explore other factors such as haptic (touch), auditory and visual cues that improve or reduce tolerance. In turn this will allow better design of environments suitable for people with compromised balance. The research will be supported by a state-of-the-art infrastructure (the EPSRC VSimulators virtual reality and motion simulation facility) at Exeter. Human and structure movement and force data will be collected using a range of technology such as optical motion capture, force plates, inertial measurement units, automated motion capture systems (CODA) and wireless technologies (IMUs). Linear and non-linear relations of human body and (structure) floor movement will be modelled mathematically.The novel engineering and/or physical sciences content of the research (the science that places it within EPSRC's remit):The project will use the VSimulators facility (EP/P020690/1). The novelty is that this will be the first time to combine motion capture, virtual reality and ground reaction force measurement on an a simulated moving structure (building, bridge) or transport (bus, tram, train, plane). This will provide unparalleled opportunities to study all the factors at play, with a very large parameter space.

亲爱的EPSRC工作人员：我理解你可能很难将这个项目纳入一个特定的研究领域，因为它是跨学科的。它是结构工程和运动科学的界面，对医学康复和健康老龄化具有重要意义。该研究项目试图解决的问题/项目目标：人类在移动的表面站立或行走时使用的平衡和控制方法是什么？这个话题尤其重要，因为中风患者、帕金森氏症患者、膝关节/髋关节置换术恢复期患者或老年患者的平衡控制能力可能会受到损害。这样的人在站立时就不太稳定，更容易在地板移动时遇到问题，这不仅可能发生在空中、铁路、公路或水运中，也可能发生在垂直活泼的地板、人行天桥或看台、摇摆的人行天桥甚至高层建筑上。即使是年轻人和身体健全的人，对这种运动的耐受性也知之甚少，而且没有关于降低这种耐受性的因素的信息。回答这些问题的方法（学生实际将做什么）：研究将探索不同类型的地板运动（滚动，俯仰，起伏和摇摆）在不同水平和频率下的平衡和稳定性机制，代表运输和结构的真实情况。它还将探索其他因素，如触觉、听觉和视觉线索，以提高或降低耐受性。反过来，这将允许更好地设计适合平衡受损的人的环境。这项研究将由埃克塞特大学最先进的基础设施（EPSRC VSimulators虚拟现实和运动模拟设施）提供支持。将使用一系列技术收集人体和结构的运动和力数据，如光学运动捕捉、力板、惯性测量单元、自动运动捕捉系统（CODA）和无线技术（imu）。人体和（结构）地板运动的线性和非线性关系将被数学建模。研究的新颖工程和/或物理科学内容（将其置于EPSRC职权范围内的科学）：该项目将使用VSimulators设施（EP/P020690/1）。新颖之处在于，这将是第一次在模拟移动结构（建筑物、桥梁）或交通工具（公共汽车、有轨电车、火车、飞机）上结合动作捕捉、虚拟现实和地面反作用力测量。这将提供无与伦比的机会来研究所有起作用的因素，具有非常大的参数空间。
