生態資訊介面圖像設計及使用性研究──以台灣特有鳥類為例

Ecological Information Interface Graphic Design and Usability: A Case Study on Endemic Bird Species in Taiwan

本研究採螺旋模式，透過鳥類圖像設計、互動架構與介面設計、啟發式評估與使用性測試等流程，進行台灣特有鳥類 app 的設計與使用性研究，並透過網路問卷招募 20 歲以上，持有智慧型手機，且習慣使用社群軟體的台灣成年人作為受試者，研究採用遠端進行使用者測試，經篩除無效樣本後，有效樣本包含實驗組 33 位與控制組 34 位，共 67 位。測試結果使用驗證性因素分析、獨立樣本 T 檢定與迴歸分析進行檢定，以提供設計與教育領域在制定生態相關資訊架構時之參考依據。結果顯示本研究所設計之 app 系統使用性總分為 74.773，介於「好」與「非常好」之間，在可靠性、刺激性、新穎性的使用經驗等級為「非常好」；吸引力與效率為「好」，清楚程度則「高於平均值」，且與自然攝影與文字圖示之介面在使用性與使用經驗上有顯著差異，說明在相同的生態資訊互動架構下，使用圖形描繪手法簡化的鳥類圖像與圖示之介面，有助於提升系統使用性，以及使用者經驗中系統的清楚程度、效率與可靠性。迴歸分析結果說明，使用者對產品的整體評價與系統的使用性、務實性、享樂性三者間均為正相關，其中，以務實性中的可靠性與享樂性中的新穎性，對整體評價的解釋力最高。

This study investigated the design and usability of an app for Taiwan’s endemic bird species. The test adopted an unmoderated remote usability testing, and the participants were Taiwanese adults holding a smartphone and accustomed to using social networks. The valid samples of the usability test were including 33 participants in the experimental group, 34 participants in the control group. The test results were verified using confirmatory factor analysis, independent sample T-test, and regression analysis to provide references for developing ecological information frameworks in the design and education fields. According to the results, the app system designed had a usability score of 74.773; was rated “excellent” in dependency, stimulation, and novelty under user experience; was rated “good” in attractiveness and efficiency, and was rated “above average” in perspicuity. A significant difference in usability and user experience was observed between the interface based on nature photography and text icons and the interface based on bird images. Accordingly, when the same ecological information interactive framework is applied, the use of graphic rendering to create simplified interface based on bird images and icons helps improve the usability of the system, as well as the perspicuity, efficiency, and dependability of the system in terms of user experience. The regression analysis results showed that the users' overall app evaluation was positively correlated with the system's usability, pragmatic quality, and hedonic quality. Furthermore, the dependability in pragmatic quality and the novelty in hedonic quality reached the highest coefficient of determination.
