Abstract: The development trend of automobile driving information brings challenges to the driving experience of the elderly users. In order to reduce the difficulty of digital interface interaction and compensate for the decline of elderly users' body, it is necessary to make the automobile digital interface more suitable for the aged and more inclusive from the perspective of man-machine interaction system. Based on the analysis of the characteristics of perception, cognition, behavior and emotion of the elderly driving users, combined with Maslow's hierarchy of needs theory, this paper puts forward the three-dimensional demand hierarchy structure of "sensory aesthetics-interactive safety-emotional experience" of automobile digital interface for elderly users. In addition, the design model of automobile digital interface interaction experience for the elderly users is constructed from the perspective of "man-vehicle-environment" system. Finally, the design practice is carried out with the vehicle central control digital interface as the carrier, which provides reference for interaction design of automobile digital interface in the aging society.
