Research on the design of elderly suitability for subway station intelligent sign system under affordance theory

Abstract

In recent years, the aging process of China's society has accelerated, and the problem of old-age care has aroused widespread concern in society. The subway plays an increasingly important role in the urban public transportation system. Therefore, an intelligent sign system is designed. The three-dimensional environment of public space is displayed as a seamlessly connected plane environment by using virtual reality technology and quasi-physical elements consistent with the knowledge and experience of the elderly, in which the vision of public space is matched. The ASM model is used to quantitatively analyze the availability of the intelligent sign system from four dimensions: vision matching, utility-oriented analysis, interaction experience and visual effects, and proposes suggestions to optimize the subway sign system for the elderly, and puts forward design principles for the intelligent sign system.
