Recognition Research and Innovative Design of Icons in In-Vehicle Infotainment System

The icons and their recognition are of great significance to the development of electrification, intelligence, networking and sharing of vehicles all over the world. The intelligence of vehicles also puts forward higher requirements for the icon design of the in-vehicle display screens. Based on relevant research results at home and abroad, based on user experience and user needs, this paper adopted the case study method, used 24 icons for different purposes in three different systems such as Carplay, Android Auto, and CarLife to carry out paired tests, carried out a questionnaire survey, and discussed the usability of icon design, as well as the characteristics for recognition and the reasons for confusion or misunderstanding. The experimental results showed that the correct recognition rate of 4 icons was more than 90%, and the correct recognition rate of 13 icons was less than 60%. 73.6% of the subjects thought that the quality of the icons was very important and would affect the use of the car. At the beginning of using the car, 68% of the subjects often or occasionally misunderstood the icons of the in-vehicle system. The subjects held that the current in-vehicle system had some problems, such as low accuracy, single color, poor human-computer interaction experience and insufficient usability optimization in the driving environment. Finally, the paper has put forward the influence of six key elements for discussion, such as interface, color, icon recognition rate, icon features, icon shape, research and sorting, in order to make efforts in usability and innovation.
