Research on Emotional Interaction Carriers of Driving Assistants in Service Scenarios of Self-Driving Automobiles

Existing in-vehicle interactive products mainly serve the drivers’ in-vehicle interactive behavior. When self-driving technology is applied to service scenarios in the future, driving behavior is simplified and cars entirely become mobile spaces, then human-computer interaction mode in a car will change and emotional sustenance and connection of passengers in the mobile space will rely more on car interactive products. Overly simple or complicated interactive emotional communication cannot produce a good experience. Based on the future service scenarios in driverless vehicles, this paper analyzes the interaction emotions required by passengers. Using eye movement and abstract emotion methods to compare and test the three existing in-vehicle interactive products (screen, abstract human form, and holographic projection), this research experiments and analyzes the degree of user visual perception when different interactive carriers convey the same emotion. The new technologies and physical assistants in combination will being conveniences for future driverless automobiles to design driving assistants on this basis in service scenarios and build a trusted atmosphere in in-vehicle space. The key factors affecting user experience in the human-vehicle interaction carrier design are summarized, and guidance is provided for the design for self-driving service scenarios.
