學習型行動加值服務人機介面分析

Abstract

本研究的目的在分析目前學習型行動加值服務的人機介面。選定大部分電信業者提供的四個英語學習型行動加值服務進行分析。研究者首先依據相關文獻及參考專家學者意見發展學習型行動加值服務評量表，評鑑範圍包括對介面整體感受、系統狀態呈現、使用者操作回饋、介面設計清晰性、使用者控制需求、介面設計一致性、與錯誤預防與處理等七個向度，使用者評鑑由資訊教育研究所研究生與審核行動加值服務的專案經理進行。 分析結果發現：目前語言學習型行動加值服務之人機介面設計具一致性，且畫面簡潔，使用者對介面之整體感受尚稱滿意；但在使用者控制需求與操作回饋方面則可再加強，而圖片與文字的顯示太小，也是許多使用者提及的問題。建議未來研究可參考本研究所發展的人機介面評量表作學習型行動加值服務之評鑑。This study evaluated the user interface of four popular value-added mobile learning service provided by the telecom companies in Taiwan. Each service was evaluated by two groups of users, one group was 10 graduate students from computer education institute and the other group was 12 project managers of value-added mobile services. Each service was evaluated from the following seven features of user interface: overall feels, visibility of system status, aesthetic and minimalist design, informative feedbacks, user control and freedom, consistency and standards, and error recover and prevention. The evaluation results showed that the user interface of the mobile learning services had a consistent design, met the principle of brevity and aesthetic, and were overall satisfied by the users; however, improvements might be needed on the aspects of informative feedback and freedom of user control, and many users complained that the icons and texts in the PDA screen were too small to see.
