Abstract
Interface less interaction is the interaction without physical or virtual visual interface. This paper studies the status quo of interface less interaction, conceptual definitions and practical applications under the concept of pervasive computing. The article analyses the influence of habit patterns on the system interaction effect, and proposes a natural interaction design process based on the habit patterns of user groups. Define the user group habit form matrix, and establish a new natural interaction system design method based on this. This interactive design method can help designers develop automatic service interface interfaces that are easy for public users to understand and use, reduce the user’s cognitive load, and better meet the cognitive diversity needs of automatic service interface users.
