This study formulated the simultaneous display interface (SDI) to enhanced hospital online register system. We conducted a focus group interview to examine existing hospital online register system. The result indicated that current hospital online register systems mainly apply wizard interface for leading the user through the interface step by step to do tasks in a prescribed order, however experienced users may suffer from elaborated steps. Based on the theory of OPD, universal usability; and interface consistency, this study proposed the simultaneous display interface for hospital online register system. By utilizing technology acceptance model, which is based on the factors of usefulness and usability, the usability of SDI was compared with that of wizard interface. Two stages experiment were carried out to verify SDI’s universal usability. Task 1, focused on usefulness, usability, employing QUIS (questionnaire for user interaction satisfaction) and SUS (system usability scale), and then analysed by SPSS for paired samples T-test analysis. Task 2, focused on young, middle-aged and older adult, testing learnability of SDI experiment. Two main conclusions as follows: (1) Simultaneous display interface accommodate individual differences among users: users with different experience positively confirmed the usefulness and usability of SDI. User’s attitude toward use and intention to use were in favor of SDI than wizard interface. (2) Learnability was improved when providing with appropriate operation prompt: Unlike other age groups, older adults take longer time to complete the task. However, the efficiency was improved especially when providing with appropriate operation prompt.
