Human-Machine Interaction (HMI) is definitely considered to play a pivotal role in advancing smart manufacturing systems in today's Industry 4.0 age. In this context, the chapter considers how IoT technologies are converging with EEG-based interfaces to refine HMI within Industry 4.0 frameworks. The introduction gives a thorough overview of the 4th industrial revolution (i.e., Industry 4.0), focusing on its transformative influence on automation and data exchange within manufacturing processes. Real-time knowledge of cognitive states is essential to maximize humanmachine collaboration, and EEG technology is presented as a key means for monitoring brain activity. The recognition of the relevance and impact HMI has in the context of smart manufacturing is demonstrated, evincing how it facilitates efficiency on factory floors, secures operations, makes them safer, and reinforces business decisions to be taken in real-time. The chapter also provides an explanation of how the Internet of Things can contribute to Industry 4.0 by connecting devices and exchanging data almost effortlessly. Incorporating EEG with IoT even allows formonitoring and analysis of human cognitive states in real-time, thus creating adaptive manufacturing environments where machines respond immediately based on updated human intent and condition. It also increases efficiency during operation hours by keeping workers in an optimal working condition. Machines look for factors that induce stress or fatigue and set them straight before they occur. Integrating EEG and IoT technologies represents a paradigm shift in HMI, offering manufacturers unprecedented insights into human cognition and behavior. By leveraging EEG data through IoT-enabled systems, manufacturers can optimize task allocation, personalize user interfaces, and even predict maintenance needs based on cognitive workload. This chapter argues that such advancements are critical for achieving higher productivity, quality, and safety standards in modern manufacturing. To sum up, this chapter elucidates EEG-based IoT-integrated interfaces for revolutionizing HMI from an Industry 4.0 perspective. These technologies improve operational confidence by facilitating real-time monitoring and adaptive responsiveness, making them ideal enablers for future smart manufacturing.
