Locomotor adaptations in relation to mode and environmental factors

自推进位移可以采取多种形式（如两足、轮式），但总是需要由环境和意图驱动的支撑、平衡和轨迹控制（方向和速度）。虽然我们对行走的预期控制有了很多了解，但诸如跨越障碍物的下肢独立性，以及在更大的人-环境连续体中规避障碍物（特别是社会因素和运动模式）的因果关系等问题仍然没有得到很好的理解。我的长期目标是：1)研究与预期运动适应相关的个人和环境因素之间的相互作用；2)改进测量这种相互作用的技术。关于这两个领域，未来五年的项目旨在：1a -了解平衡和阶梯控制之间的关系，以及环境障碍物的物理特性；1b -区分与环境因素相关的通用和特定模式的运动导航控制；c -相关的运动导航控制与物理和社会环境因素；创新运动虚拟现实协议，模拟身体社交接触。

Self propelled displacement can take many forms (e.g., biped, wheeled), but always requires support, balance, and trajectory control (direction and speed) driven by the environment and intent. While we are learning much about anticipatory control of walking, issues such as lower limb independence for stepping over obstacles, and the cause-effect relationships within the larger person-environment continuum for circumventing obstacles (particularly for social factors and locomotor mode) are still not well understood. The long-term goals of my program are to: 1) study the interaction between personal and environmental factors related to anticipatory locomotor adaptation; and 2) advance technology to measure such interaction. In relation to these two areas, projects over the next five years are designed to : 1a –understand the relation between equilibrium and stepping control with respect to the physical characteristics of environmental obstructions; 1b–differentiate generic from mode-specific locomotor navigational control related to environmental factors; 1c–relate locomotor navigational control to physical and social environmental factors; and 2–innovate locomotor VR protocols to simulate physical social contact.
