BackgroundPsychological anxiety is an emotional response that includes emotional states such as nervousness, worry, and uneasiness. By understanding the effects of human-computer interaction systems on users’ psychological anxiety, designers can take appropriate measures to reduce users’ psychological anxiety and improve their satisfaction and efficiency.
Subjects and MethodsSeventy-two participants were selected for this study and randomly divided into an experimental group and a control group, with 36 participants in each group. The experimental group was exposed to HCI systems that used specific interface designs, and the control group was exposed to traditional HCI systems. The experimental data were collected by recording the psychological responses and behavioral performance of the participants such as psychological anxiety level and task completion time when using the interface. The data analysis software used was SAS.
ResultsThe average psychological anxiety level scores of the experimental group and the control group were 3.5 and 4.2; and the average interface task completion time of the experimental group was 9.3±1.2 minutes, while the average time of the control group was 12.2±1.5 minutes. Through comparative analysis, there is a difference between the experimental group and the control group with P<0.05.
ConclusionsBy studying the effect of HCI on users’ psychological anxiety, can help designers improve the design and function of HCI systems, reduce users’ psychological anxiety, and improve users’ satisfaction and efficiency.
