隨著科技發展，智慧型手機及行動網路的快速發展，串流影音服務越來越發達，各種不同於以往的娛樂將因應而生。由於科技的進步，行動音樂服務從錄音帶發展到CD Player到現今主流的數位音源，不但改變了喜好音樂者的生活型態，也改變了音樂發行商的經營模式。逐漸減少的唱片行都轉變為網路音樂平台，而播放音樂的硬體裝置從原先的實體裝置轉變成為智慧型手機上的應用程式。有鑒於此，設計師與工程師著重在智慧型手機應用程式的開發與設計，以吸引使用者的目光。本研究目的希望藉此研究成果來改善現有串流音樂應用程式的使用者介面來帶給使用者有更好的使用體驗。

本研究包含兩部份實驗：(1)前導性實驗設計：調查現有串流音樂應用程式做為前導性實驗樣本，以便了解目前串流音樂應用程式之優缺點，包含操作功能及介面呈現方式、系統易用性、介面互動滿意度，並透過觀察、使用者訪談及問卷調查法得知使用者的需求及介面改善之建議。(2)驗證實驗：透過文獻探討之理論作為依據，驗證實驗採2 (使用者經驗有無) x 3 (介面配置型式)雙因子實驗方式進行，進行介面模擬實驗與驗證，包含操作任務績效計測、使用者主觀感受評量、系統使用性尺度量表(SUS) 、使用者互動滿意度量表(QUIS)，將實驗結果做個別與整體分析探討，最後提出實驗的結論與建議。

研究成果歸納出下列成果：(1)整體設計而言「首頁大版面顯示」操作直覺性最高，易視性好，具有良好的概念模型，使用者的滿意度最高。(2)介面的美術呈現在不影響使用者的辨識下適時增加些許細節以增加畫面的豐富性。(3)介面入口的設計應該清楚明瞭。(4)不要為了介面美觀而犧牲該有的易視性。(5)介面之間避免互相干擾影響。(6)常使用的介面必須容易辨識。

With the rapid development of digital technology for smart phones and mobile networks, streaming video and audio services are becoming more and more important in our daily lives. Therefore, portable music services have evolved from audio tapes to CD players to today's mainstream digital audio sources. Not only it has changed the lifestyle of music lovers, but it has also changed the business model of music publishers. The decreasing record store have turned into online music platforms, and the hardware devices that play music have changed from the original physical devices to the applications on smart phones. In view of this, designers and engineers focus on the development and design of smart phone applications to attract consumers' attention. The research purposes of this study are to improve the user interface design of the existing streaming music application to provide customers with a better user experience.

This study consists of two experiments: (1) Pilot experiment: The purpose is to investigate streaming music applications. The experiment was conducted to help understand the advantages and disadvantages of current streaming music applications, including operational functions, interface presentation methods, system usability, interaction satisfaction, and the understanding of user needs and suggestions through observation and user interviews; (2) Verification experiment: Based on the theory from literature review and results from pilot experiment, the verified experiment was a 2 (higher or lower user experience) by 3 (interface configuration type) two-factor experiment design The dependent variables were operation performance, subjective evaluation (i.e., USE questionnaire) and System Usability Scale (SUS). The experimental results are discussed individually and, in overall, conclusions and recommendations are presented.

The research results are summarized as follows: (1) In terms of the overall design, the “Homepage Large Layout Display” has the highest intuitiveness, good visibility, and a good conceptual model and with the highest user satisfaction. (2) The arts presentation of the user interface adds some details in order to increase the richness of the picture without affecting the user's identification. (3) The design of the user interface should be clear. (4) Do not sacrifice the visibility for the aesthetics of the interface. (5) Avoid interference with each other among interface pages. (6) Commonly used user interfaces must be easily identifiable.
