The work aims to analyze the characteristics of the elderly's unconscious behavior when using entertainment products to re-optimize the design methods of the elderly entertainment products, and provide a new way for the development of product design theory. By tracing the historical research results of unconscious behaviors, the product information, emotional cognition, context and other factors related to the behavioral logic used by elderly users are classified and researched based on the aging population, obvious behavior characteristics and weak related design. The behavioral characteristics of the elderly in the use of entertainment products are summarized, and then specific methods of product design to guide unconscious operation are deduced. Compared with the design of things, the design of behavior can better stimulate and tap the potential needs of users. By replacing the local use behavior of the elderly during the operation of the product, the experience difficulty of the product can be reduced, and an interactive entertainment state can be achieved without thinking. In addition, based on the relationship between behavior and perception, the association between the information of things is found, and the interaction process between the user group and the product is transformed into the reduction of information perception and contextual experience, which provides new possibilities for better control of the psychological emotions of elderly users and reducing the invalidity of the experience.
