Elderly-friendly Design of In-vehicle Navigation Interface in New Energy Vehicles from the Perspective of Implicit Interaction

Abstract

To enhance the user experience and safety of the interactive interface in new energy vehicles, this study explores the age-friendly design methods for the in-vehicle central control navigation interface from the perspective of implicit interaction. Through literature analysis and questionnaire surveys, factors influencing the age-friendliness of automotive interactive interfaces were obtained, and the influence weights of different factors were calculated using the entropy weight method. Based on the calculation results, key requirements were extracted from three aspects: interface layout, interface elements, and interaction feedback, and a practical age-friendly design plan for the central control navigation interface was further proposed. On this basis, elderly drivers were recruited to conduct simulated interaction experiments, and the completion time of navigation tasks was collected. By comparing the operational performance of the navigation interface under explicit and implicit interaction schemes, the usability of this plan was verified. The experimental results show that the central control navigation interface under implicit interaction can effectively shorten the interaction time and improve the interaction experience of elderly drivers. Based on this, this study proposes age-friendly design strategies for the central control interface from three aspects: multi-sensory design, simplification of the interface hierarchy structure, and adaptive adjustment of the interaction interface, thereby providing new theoretical references for the age-friendly design of new energy vehicle navigation interfaces.
