良好的人機介面應以使用者為中心,並包容不同使用族群。本研究探討同步呈現介面應用於醫院網路掛號系統之操作性,首先透過焦點團體討論,對現有醫院網路掛號介面進行分析,發現其操作介面多採用精靈模式,主要是為了滿足新手使用者,但熟練的使用者則嫌其煩瑣。 在OPD、通用使用性、一致性及人機介面的理論下,本研究提出同步呈現介面取代精靈模式,將其應用於醫院網路掛號系統,並透過科技接受模式中「有用性」與「易用性」,與精靈模式介面相互比較,進行兩階段任務實驗,驗證其通用使用性。 任務一針對有用性、易用性,以及QUIS使用者互動滿意度、SUS系統使用性量表,透過SPSS進行成對樣本T檢定分析;任務二針對高齡者、中高齡者及青壯年進行同步呈現介面之學習績效分析。根據實驗結果,本研究提出以下2點結論: (1)同步呈現介面比精靈模式介面較能包容不同階段之使用者:不同經驗使用者對於同步呈現介面之有用性與易用性皆給予較高的評價;對於使用者態度及持續使用意圖亦優於精靈模式介面。 (2)適時的操作提示可改善其學習績效:高齡者操作同步呈現介面之操作績效較其他使用者低,但透過適時的操作提示可改善高齡者學習績效。
A properly implemented human-computer interface should be user-centered design and usable to all people. 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.
