拜數碼產品技術的日新月異所賜，越來越多的動態設計形式可以在介面當中流暢運行，同時，在信息量爆炸的今天，人們每天都要使用各式各樣的APP，流覽五花八門的介面，這其中又以炙手可熱之網路購物APP及其相關衍生物為重中之重。動效的加入好似一劑良藥，為介面中繁雜的資訊增添了一絲明晰之意。把握住恰到好處的動效，用戶對於介面的沉浸感與對待產品之忠誠度便會呼之欲出。
本研究包含兩個階段：(1) 前導性實驗設計；以「宜家家居」APP為基礎製作出分別帶有動態與靜態提示點的樣本，用於測試介面中動效之有無對於用戶的影響，再以同樣之基礎製作帶有不同動態提示點的樣本，用於測試介面中動效之動態差異對用戶之影響，並為後續的驗證實驗提供可參考之自變項設定依據。(2) 驗證實驗：以前導性實驗及文獻作為依據，驗證實驗採用3(動態：縮放、位移、陰影疊加) * (頻率：快、慢)雙因數混合實驗設計，兩兩組合配對共計6個樣本，實驗內容包含一個試驗任務五個測評項，分別為：操作時間計測、點擊各部位觸發器之次數(提示點、卡片)、用戶感受問卷，逐個分析不同的實驗樣本，最後提煉出實驗的結果與建議。
研究結果可以歸納如下：(1) 「陰影疊加」與「縮放」兩種動態在提示性與意象的營造兩方面的差異不大，但二者在以上兩方面與「位移」性動效的差異較大，所以，由此推斷在用戶的認知中，具有「閃爍意象」的，透過大小來呈現的動效，更符合用戶的認知。(2) 陰影疊加性動效在滿意度方面優於其他二者，推測在介面中合理運用陰影會加強介面之空間感，使之資訊層次更顯分明，視覺體驗更趨友好。(3) 兩個自變項之間產生之交互作用令研究者推測，動效中視覺強度的大小直接影響到動效對頻率的敏感程度，也就是說視覺信號越強烈，當高頻率介入時，其視覺吸引力便會顯著的增長。(4) 實驗中「頻率」的變項主效應體現的比較少，更多是透過與「動態」之交互作用體現於實驗結果之中。可透過「頻率」推斷出不同動態之動效對於「頻率」之敏感度。(5) 實驗結果表明動效營造之意象與視覺強度是動效的滿意度是否得到保障之關鍵。

Due to the rapid development of digital product technology, more and more dynamic design forms can run smoothly in the interface. At the same time, with the rapidly rising of network traffic, users have to use a variety of apps every day to browse through various user interfaces, among which the hot online shopping app and its related derivatives are the most important. Dynamic effect is like a good medicine, which adds a trace of clarity to the complicated information in the interface. Grasp the right dynamic effect, the user's immersion in the interface and loyalty to the product will be ready.
This study consists of two stages: (1) Pilot experiment design: Based on the IKEA app, make samples of static and dynamic prompt points. In the use of test if dynamic effect’s existence can impact on users. Then according to the same basis to create samples with different dynamic prompt points. It is intended to test the impact of difference between dynamic effects with different actions to the users, and provide a reference for the subsequent validation experiments. (2) Validation experiments: Based on previous experiments and literature, the verification experiment adopted a two factor between-subjects experimental design of 3 (dynamics: scaling, displacement, shadow superposition) x (frequency: fast, slow). Pairing two different combinations, a total of 6 prototypes were obtained. The content of the experiment includes one experiment task and five evaluation items. They are operation time measurement, times of clicking trigger of each part (prompt point, card), the questionnaire for user satisfaction. we can analyze different experiment prototypes and get the final experiment results and suggestions.
The experiment results are summarized as follows: (1) “Shadow Overlay” and “Zoom” these two dynamics seem to have no significant difference on “suggestive” and “imagery”. But there exists significant difference between “displacement” and two of them. Therefore, it can be inferred that in the user's cognition, the dynamic effect presented by size with "flashing image" is more consistent with the user's cognition. (2) “Shadow Overlay” this dynamic is better than the other two in satisfaction, which leads researcher to the conclusion that the rational use of shadow in the interface will enhance the spatial sense of the interface. Make the information level more obvious and the visual experience more friendly. (3) The interaction between two independent variables make the researcher speculated that the visual intensity directly affects the sensitivity of dynamic effect to frequency. That is to say, the stronger the visual signal is, when high frequency intervenes, its visual attraction will increase exponentially. (4) In the experiment, “frequency” this variable, shows no significant main effect, but through the interaction with “dynamic”, the influence reflected in the experimental results. Through “frequency” this variable, it could be infer that, the sensitivity about different dynamics in dynamic effects.
