This project at a primarly undergraduate institution will address the important, but still little understood question of how we perceive and identify objects by touch. More specifically, it deals with how the hand and fingertips interact with surfaces, edges, and vibrations. Understanding how we process and interpret the information we get from touching objects is increasingly important in many high-tech arenas, such as improving assistive devices or virtual simulations for training people to repair or maintain complex products, including airplanes and heavy machinery. Results of this project will broaden our understanding of the role of different types of touch receptors in the fingertips and the ways in which their signals are processed and integrated, which leads to a better understanding of grasping, sliding, and object handling. The project will investigate touch processing by presenting computer-controlled stimuli to the fingertips of adult human subjects and analyzing their reported sensations under defined conditions. The investigator is on the faculty of a primarily undergraduate institution and will provide 12 undergraduate students with multidisciplinary experience in cognitive science, improving their research and science skills, and allowing them opportunities to interact with a wider scientific community.The proposed research will address fundamental questions about the interpretation of mechanoreceptor and nerve fiber activation beyond frequency thresholds using edge perception as a practical example. This is important because humans daily touch multiple objects that include edges and ridges. The study has three aims: 1) to compare the responses of receptors to different frequencies of vibration in order to understand the perceptual mechanisms behind tactile edge perception; 2) to identify the role of motor action in an integrated approach to edge perception; and 3) to consider the role of other senses (hearing and seeing) in tactile edge perception. These experiments will advance our knowledge of the ways different touch receptors respond to edges and contours, how these responses might be processed at different levels of the peripheral and central nervous system, and the role of active and passive movement and input from other sensory systems in interpreting touch perception. The research also has important applications in touch interfaces, robotics, and tools for the visually challenged.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目在本科生的原始机构将解决重要的，但仍未理解我们如何通过触摸感知和识别对象的问题。更具体地说，它涉及手和指尖如何与表面，边缘和振动相互作用。在许多高科技领域，了解我们如何处理和解释接触物体获得的信息越来越重要，例如改善辅助设备或虚拟模拟，以培训人们修复或维护复杂产品，包括飞机和重型机械。该项目的结果将扩大我们对指尖中不同类型的触摸受体的作用以及对信号的处理和集成方式的理解，从而更好地理解抓地力，滑动和对象处理。 该项目将通过向成人人类受试者的指尖提出计算机控制的刺激来研究触摸处理，并在定义的条件下分析其报告的感觉。 The investigator is on the faculty of a primarily undergraduate institution and will provide 12 undergraduate students with multidisciplinary experience in cognitive science, improving their research and science skills, and allowing them opportunities to interact with a wider scientific community.The proposed research will address fundamental questions about the interpretation of mechanoreceptor and nerve fiber activation beyond frequency thresholds using edge perception as a practical example.这很重要，因为人类每天都接触包括边缘和山脊的多个物体。这项研究的目的是：1）比较受体对不同振动频率的反应，以了解触​​觉边缘感知背后的感知机制； 2）确定运动作用在综合的边缘感知方法中的作用； 3）考虑其他感官（听力和观察）在触觉边缘感知中的作用。这些实验将提高我们对不同触摸受体响应边缘和轮廓的方式的了解，如何在外围和中枢神经系统的不同级别处理这些响应，以及主动和被动运动的作用以及其他感觉系统在解释触摸感知中的作用。这项研究还为视觉挑战提供了重要的应用，在触摸界面，机器人技术和工具中，该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准来通过评估来支持的。
