智慧型手機的興起，逐漸取代傳統手機，成為現今手機市場的主要趨勢，也因為智慧型手機的普及影響之下，各種單一功能的設備紛紛被取代，相機就是其中的一種。更快速的網路及 Instagram、Vine 等照片分享 App 的火紅下，使用手機拍照的人越來越多了。人們因此可以隨時隨地的分享自己生活周遭的事物，不受限於地點與時間。這樣的生活方式讓各手機大廠也為了提升相機使用上的體驗，紛紛在相機技術上下功夫。
本研究包含兩部份實驗：(1)前導性實驗為針對三個品牌以強調照相功能為主的智慧型手機，進行介面使用性評估，透過計測任務了解樣本之間的差異與操作績效；(2)依據前導性實驗結果，與文獻的重點論述，進行模擬介面實驗。模擬介面採3(版面配置方式) x 2(單手和雙手操作經驗的人)雙因子組間實驗設計；版面配置方式有三組：(1)下置選單；(2)中置選單；(3)圓弧選單，有操作經驗的人有兩組：(1)單手操作經驗的人；(2)雙手操作經驗的人。
研究結果如下：(1)使用Camera App的單手操作拍照經驗時間，以2年以上單手操作拍照經驗者為主；(2)透過Camera App傳送照片分享給好友的時間，以2~3天為主；(3)在主觀感受上，圓弧選單在有單手操作經驗的操作流暢度與個人喜好接受度較為青睞；(4)在拍完一張照片並選擇建立一本相簿，中置選單的操作績效較其他兩個樣本高。

The rise of smartphones, gradually replacing the traditional mobile phone, has become the main trend in today's mobile phone market. Because under the influence of the popularity of smartphones, a variety of single-function devices have been replaced, and the camera is one of them. More and more people are using camera phones because of faster network and photo sharing from Instagram, Vine and other photo sharing Apps. Therefore, people can share their lives anywhere, not limited to place and time. Such a way of life style enables mobile phone manufacturers to enhance the use experience on camera phones.
This study consists of two parts: (1) Carrying out the pilot experiment on interface usability assessment, and understand the differences between users’ task performance regarding three camera phones emphasizing on the camera functions, (2) Based on the pilot experiment results, relevant literature, several simulation experiment interface were created. The experiment is a 3 (Layout mode) x 2 (one-hand or two-hand operation experience) between-subject two factor experimental design; The layout mode has three levels: (1) under the home menu, (2) in the home menu, (3) Round arc menu. The one-hand or two-hand operation experience have two levels: (1) one-hand operation experience, (2) two-hand operation experience.
The results are as follows: (1) The user who uses camera App of one-hand operation experience often has more than two years photographing experience, (2) The user who shares photos to a friend via Camera App often does it once in 2 to 3 days, (3) In terms of subjective feelings, the arc menu with a one-hand operation experience regarding the fluency and personal preference obrtains the most popular acceptance, (4) After taking a photo and choose to create an album, the in the menu operating performance is better than the other two samples.
