The effect of operation steps on the efficiency of human-computer interaction

In the field of human-computer interaction design, the efficiency of interaction operations has become an increasing concern, and how to complete tasks quickly and accurately has become the focus of our research. Therefore, this study took the two tasks of "information addition" and "information deletion" as typical cases, and carried out ergonomic experiments. By analyzing the physiological indicators and performance indicators of operators in the process of completing tasks, the completion of tasks under different operating steps was analyzed. The results show that the performance of the task is significantly improved after the reduction of interaction steps. This conclusion can be applied to the human-machine interface interaction design to improve the efficiency of user interaction operations.
