The Tactile Internet, described as a communication infrastructure combining low latency and high reliability, is considered as a leap compared with mobile Internet and Internet of things, and will thereby provide a revolution for almost every segment of society. When the Tactile Internet is introduced into smart city, it not only innovates existing communication and interaction, but also promotes the intelligent process of smart city and end-users' quality of experience (QoE) by taking advantage of haptic information and haptic-related applications. To fully integrate tactile technology with smart city, this article proposes a novel QoE-driven Tactile Internet architecture for smart city, containing five layers: sensing layer, transmission layer, storage layer, computing layer, and application layer. Importantly, the techniques supported in each layer of this architecture follow the requirements of low latency, high reliability, and high quality of user experience. Under this architecture, we devise a fast and reliable QoE management framework based on the broad learning system. Simulation results show that it can achieve high QoE performance under the premise of low computational complexity and high availability.
