隨著智慧型手持裝置的普及，數位元影像處理技術、應用軟體與電腦連接介面的改進，使得消費者使用影像掃描技術越來越方便，市場物件已從辦公商用轉為面向一般消費者。本研究之目的為以智慧型手機掃描應用程式探討介面舆體驗感受，研究何種文件新增方式與功能選單位置對於使用者之使用績效與能達到更好的體驗感受，以利進一步改善行動掃描應用程式介面設計，提升使用者滿意度。

本研究分三個實驗階段：（1）彙集現有行動掃描應用程式功能資料，進行問卷設計與現況調查；（2）前導性實驗：透過受測者任務操作績效及問卷分析結果，取得後續之設計改善方向；（3）驗證實驗：歸納文獻舆前導性實驗結論，進行模擬原型設計驗證。實驗設計採2（文件新增方式）x 3（功能選單位置）雙因子組間實驗方式進行，探討不同變項搭配之樣本是否有對使用者主觀感受產生影響。

研究結果彙整如下：（1）文件新增方式採「浮動式操作按鈕」在績效及滿意度上優於「跳轉式操作按鈕」；（2）功能選單位置採「選單列在下」在績效及評價中皆優於「選單列獨立」及；（3）文件新增方式採「選單列在上」時，建議採用「跳轉式操作按鈕」以提升使用者之滿意度；（4）行動應用程式應盡量提高容錯率，在發生錯誤後，使用者可以對其快速修正；（5）明確、清晰的圖示可以幫助使用者快速學會一個新應用程式的操作，具有較強的學習性；（6）在有限的介面範圍內，每一個資訊的呈現都會與主要資訊產生競爭，可透過移除介面上不必要的資訊來提升介面使用性。

With the popularity of smart handheld devices and the improvement of digital image processing technology, application software, and computer user interface, it has been becoming more convenient for consumers to use image scanning technology. Market objects have changed from office businesses to general consumers. The purpose of this study is to explore the user interface experience pertinento to the scanning application on a smart phone. That is, to study which file adding methods and function menu position can help achieve a better task operation performance and user experience in order to further improve the mobile scanning application and to improve user satisfaction.
This study is divided into three experimental stages:（1）Collect functional data of existing mobile scanning applications, and conduct questionnaire design to help investigate current situation;（2）Pilot experiment: Through the results generated from partiicpants’ task operation performance and questionnaire survey, the subsequent design improvement direction is obtained;（3）Verification experiment: Based on the results from summarized literature review and pilot experiment. Simulation prototypes were created to help carry out verification experiment. The experimental design was conducted in a two factor between-subject experimental design of a 2 (file adding method) x 3 (function menu position) in order to explore whether different research variables affect the participants’ subjective feelings.
The results of the study are summarized as follows:（1）The "floating operation button" is better than the "pop-up operation button" in terms of task operation performance and subjective satisfaction. （2）The function menu position of "listed below" is better than the "list alone" in task operation performance and subjective evaluation;（3）When adding documents by using "menu bar on top", it is recommended to use "jump operation button" to help improve user satisfaction;（4）The mobile app should try to improve the error tolerance rate, and users can quickly fix it after an error occurs;（5）Clean and clear graphics can help users quickly learn to operate a new application and have a strong learning ability;（6）Within a limited interface area, each presentation of information will compete with the main information, and the interface usability can be improved by removing unnecessary information from the interface.

Keywords：Scanning, Function menu position, Applications, User interface, System usability
