科技的創新使電子產品不斷的演變，至近年智慧型裝置的推出後，改變了現今社會大眾對於傳播電子產品的使用者體驗。其外觀及功能的多樣性、整合性、不占空間之特質之外，仍需回歸到產品與消費者所接接觸之源頭－介面之互動，而視覺設計在使用者操作上亦也占了重要的地位。本研究主要以iOS7作業系統介面之視覺設計為研究範圍，以iPad mini為樣本，分析iOS7作業系統之20個介面圖示之形、色、質等構成元素，歸納出iOS7在介 面圖示設計上之４個特點：1.圖像為主；2.背景大多使用漸層的色彩；3.使用漸層背景的圖像以白色居多；4.icon的色彩運用大多不超過3個顏色。並將iOS6及iOS7作業系統作圖示及視任性比較之分析，歸納出之特點可作為往後在介面設計上之參考及運用。

The innovation of technology has led to constant evolution of electronic devices. The launch of smart phones and devices has changed people's experiences of using electronic media devices nowadays. In addition to the diversities of appearance and function and the characteristics of integration and space-saving; the source of consumers' contact with products, the interactivity of interface, is needed to be investigated as well. The main scope of this research is the visual design of the interface of iOS7. This research is the analysis of components of shape, color, and quality of twenty interface icons of iOS7, with iPad mini as sample. Four features of the interface icons of iOS7 are summarized as follows: firstly, icons are mostly images; secondly, icons' backgrounds are generally gradient colors; thirdly, the gradient colors are mainly white; and fourthly, there are no more than three kinds of colors being used in an icon. The aforementioned characteristics can be regarded as references and applications on interface design in the future.
