Braking to Avoid a Collision: Information, Control, and Dynamics

一个孩子跑过一扇旋转门所做的事情与一只落在树枝上的鸟是一样的。这两种情况都会产生软碰撞，而不是完全避免接触。软生存碰撞也可以在尝试中发生巨大变化的情况下进行，考虑海军飞行员降落在航母甲板弯曲表面的情况。为了理解人类和动物是如何成功地进行软碰撞的，科学家们必须解释所有这些情况下的软碰撞。在美国国家科学基金会（National Science Foundation）的支持下，Brett Fajen博士的研究旨在了解人们如何适应各种条件，以成功地完成软碰撞，或者只是避免与运动路径上的障碍物碰撞。这项研究将使用模拟器进行，在模拟器中，法詹博士可以系统地改变任务、环境和动态约束，并观察人们如何适应这些变化。该项目的广泛影响包括运输安全、移动机器人设计、远程车辆操作以及对人类视觉运动缺陷的更深入了解。该项目通过支持伦斯勒理工学院两门新课程的开发，将研究和教育结合起来，并为本科生和研究生提供参与研究的机会

A child who runs through a swinging door does something in common with a bird that lands on a tree branch. Both cases produce soft collisions rather than avoiding contact altogether. Soft survivable collisions can also be made in circumstances that change dramatically in the attempt, consider the circumstances of a Navy pilot landing on the bucking surface of a carrier deck. To understand how people and animals succeed in their capacity for soft collisions, scientists must account for soft collisions in all these situations. With support from the National Science Foundation, Dr. Brett Fajen's research aims at understanding how people adapt to a wide range of conditions to successfully accomplish soft collisions or simply avoid collisions with obstacles in the path of motion. The research will be conducted using a simulator in which Dr. Fajen can systematically vary the task, environmental, and dynamic constraints, and observe how people adapt to such changes. The broader impacts of this project include applications to transportation safety, the design of mobile robots, teleoperation of vehicles from remote locations, and a deeper understanding of visual-motor deficits in humans. This project integrates research and education by supporting the development of two new courses at Rensselaer Polytechnic Institute, and providing opportunities for undergraduate and graduate students to participate in research
