In the competitive landscape of modern business, marketers face the critical task of deeply understanding consumer behavior to craft personalized brand experiences and impactful campaigns. This paper introduces a novel approach by integrating brainwave analysis, virtual reality (VR), and artificial intelligence (AI) to revolutionize AI-driven brand marketing. By examining electrical brain activity (EEG), marketers can gain objective insights into consumer attention, emotional engagement, and relaxation. VR technology enhances these insights by providing immersive experiences that build stronger connections with consumers. Furthermore, the application of AI and big data analysis allows for the prediction of consumer preferences and the optimization of brand interactions. Our research adds significant value to the field by demonstrating that VR media significantly enhances consumer attention and relaxation compared to traditional print media. Consistent and highly engaged consumer experiences are indicated by distinct patterns in reactions to VR. The ability to analyze brainwave data offers marketers precise measurements of cognitive and emotional responses, enabling the development of highly personalized and effective marketing strategies. AI further enhances these strategies by forecasting consumer behavior and customizing interactions, setting a new standard for consumer engagement. This innovative approach redefines marketing strategies, making them more precise and personal, paving the way for a future where brand marketing is more innovative and closely connected to consumers.
