This paper aims to analyze the changes in the relationship between humans and tools caused by the technological revolution, study the aesthetic changes and development rules in the three stages of machine aesthetics, technological aesthetics, and cognitive aesthetics since the Industrial Revolution, and explore the development trend of intelligent product design aesthetics. This paper analyzes the development of product design aesthetics triggered by technological revolution through literature research and product case, comb and compares the development direction of smart product aesthetics based on the literature review of emotional computing, neuroscience and philosophical ethics. The relationship between humans and tools in the three development stages of machine aesthetics, technical aesthetics, and cognitive aesthetics is reflected in operational relationships, synergistic relationships, and interactive relationships. The relationship between product functions and forms is reflected in form following functions, form awakening functions, and form mapping function; smart products show the fusion relationship of perception, behavior, and emotion in the human-machine relationship, and the form is gradually separated from function; smart product design aesthetics should focus on sustainable development, social ethics, emotional alienation and excessive dependence. The design strategy of “appropriate intelligence” is adopted for smart products, and the “intelligence aesthetics” is gradually formed.
