智慧型照相手機之介面研究與設計
The research and design of the interface of camera smart-phone
摘要
科技產品爆炸的時代中，手機已成為不可或缺的重要產品。觸控面板導入手機後，以往以按鍵操作為主變成以觸控介面為主流。本研究想了解觸控按鍵或實體按鍵操控之下，對於拍照與通話功能的影響，提出智慧型照相手機較佳配置。以問卷調查70位受測者對於智慧型照相手機的使用理由、操作方式、按鍵功能與形式喜好程度，發現使用智慧型手機照相功能的理由主要為隨時隨地紀錄生活、快速分享照片到網路社群、不用同時攜帶相機與手機。理想的整體大小偏中尺寸(約115x59 mm)，螢幕偏大(約4.3吋)，厚度偏薄(約8.5 mm)。以重複量數分析通話與照相功能操作滿意度、手機與照相功能鍵必要程度，發現受測者喜好觸控操作方式，其中調整音量和拍攝照片偏好實體鍵操作，而電源、拍照/攝影切換、閃光模式、快門、近拍等鍵最為重要。以卡方分析手機和相機功能鍵傾向，其中相機功能鍵受測者喜好偏向觸控按鍵型式。 操作與按鍵配置研究中請6位攝影專家做實體與觸控按鍵配置建議，之後由36位一般智慧型手機使用者進行專家配置建議驗證，方式以實體模型與操作概念影片介紹，實驗完成後以滿意度問卷調查，實驗結果挑選一組受測者最滿意之實體與觸控按鍵配置進行設計。 依照操作與按鍵配置研究結果進行介面設計改良，與S廠牌產品做客觀任務與主觀滿意度問卷比較。客觀任務：解鎖至拍照、多項功能調整後拍照、拍照時電話插播，並紀錄錯誤次數與操作時間。主觀滿意度問卷使用SUS系統易用性量表與NASA-TLX心智負荷量表。操作時間用相依樣本t檢定得知任務三本實驗設計介面顯著少於S廠牌；錯誤次數用相依樣本t檢定得知任務二與任務三本實驗設計介面顯著少於S廠牌。主觀量表用相依樣本t檢定SUS與NASA-TLX量表發現本實驗設計介面優於S廠牌介面。

At the present time, the mobile phone has already become an indispensable product. Touch panel also has become the mainstream of the smart-phone control interface. In this study, the purpose is to propose a better configuration of camera smart-phone for physically-touching control to take picture. In accordance with the reason to use, operation mode, and the key function of the camera smart-phone, there are 70 survey subjects designed in a questionnaire. The reasons for using the camera smart-phone are recording life anywhere, sharing photos quickly via the internet environment, and carry camera and mobile phone at the same time. The ideal overall size is approximately 115x59x8.5 mm with a 4.3-inch screen. The repeated measure of ANOVA is used to analyze whether the satisfaction of phone and camera function operation, and the extent necessity of phone and camera function keys are meet. According to the ANOVA analysis with regard to the questionnaire, it is shown that the touch operation is preferred. Within the functions of the smart-phone, physical control to adjust the volume and take a picture is preferred. The important keys are power, switching camera or video recording mode, flash mode, shutter, and macro mode. Chi-square analysis is used to analyze the tendency of phone and camera function keys, it is demonstrated that touch buttons for camera function is preferable. In research of the operation and button configuration, firstly the button configuration recommendations are suggested from 6 professional photographers. Expertise configuration recommendations are then verified by 36 normal users. The verification method used entity models and operating concept videos. At last, the best model is chosen to modify and design the configuration. Finally, this study’s design interface is compared with the “S” brand’s by objective tasks and subjective satisfaction questionnaire. The objective tasks contained “unlocking the phone to taking picture”, “adjusting some camera functions before taking picture”, and “having a phone call at taking picture”. All objective recorded the number of errors and operating time. The subjective satisfaction questionnaire used System usability scale (SUS) and NASA-TLX. The operating time and errors analyzed by paired-sample t test. The results showed the study’s design interface was shorter than “S brand” at the time of the task 3; the study’s design interface was less than “S brand” at the errors of the task 2&3. The subjective satisfaction questionnaire analyzed by paired-sample t-test. The results were shown the study’s design interface was better than “S brand” at SUS and NASA-TLX.
