Haptic perception uses signals from touch receptors to detect, locate, and mentally represent objects and surfaces. Research from behavioral science, neuroscience, and computational modeling advances understanding of these essential functions. Haptic perception is grounded in neural circuitry that transmits external contact to the brain via increasingly abstracted representations. Computational models of mechanical interactions at the skin predict peripheral neural firing rates that initiate the processing chain. Behavioral phenomena and associated neural processes illustrate the reciprocal relationship by which perception supports action and action gates experience. The interaction of sensation and action is evident in how features of surfaces and objects such as softness and curvature are encoded. By incorporating touch sensations in conjunction with motor control, biologically embedded prosthetics enhance user capabilities and may elicit feelings of ownership. Efforts to create virtual haptic experience with advanced technologies underscore the complexity of this fundamental perceptual channel and its relation to action.
触觉感知利用来自触觉感受器的信号来检测、定位物体和表面，并在脑海中形成其表征。行为科学、神经科学和计算建模方面的研究推动了对这些基本功能的理解。触觉感知基于神经回路，该神经回路通过越来越抽象的表征将外部接触传递给大脑。皮肤机械相互作用的计算模型预测启动处理链的外周神经放电率。行为现象和相关的神经过程说明了感知支持行动和行动控制体验的相互关系。感觉与行动的相互作用在表面和物体的特征（如柔软度和曲率）的编码方式中很明显。通过将触觉与运动控制相结合，生物植入式假肢增强了用户的能力，并可能引发拥有感。利用先进技术创造虚拟触觉体验的努力凸显了这一基本感知通道的复杂性及其与行动的关系。
