Design of human-computer interaction interface considering user friendliness

Analysis and modelling for interactions on self-service terminal interface have been made in this paper based on distributed cognition theory, which is to confirm the relationship between interactions and information presentation in human-computer interaction and propose interface interaction design method of self-service terminal based on user cognitive ability. With adoption of this method, designers need to make research on users and identify the user group that needs to be taken care of firstly, and then make analysis of cognitive ability, set up user cognitive load model, describe the interactive behaviour of users, confirm basic interaction frame, and then establish interaction design matrix with universal usability design model and propose interactive design program. We take hotel self-service terminal as example, adopt this method to make design program and then verify the effectiveness of the proposed design method through making comparisons with design program formed by traditional method. This interactive design method can help designers develop self-service terminal interface that is suit-Able for people to understand and use, decrease the cognitive load of users and meet the diversified demands of self-service terminal users for cognition.
