Weblog軟體服務可說是一獨立媒體中心與個人線上出版系統概念的呈現，屬於開放式簡易網路工具，亦是近兩年來新興的網路合眾媒體。Weblog正微妙的改變當前網路資訊的傳播方式，讓資訊分享更加容易、更有效率。透過Weblog軟體服務，使用者可快速的建立一線上個人空間，但Weblog功能與介面設計仍有諸多值得深入探討之空間，例如使用者對Weblog功能與介面設計之切確需求為何？如何避免因提供樣板而造成制式化的網頁版面呈現？以及應用情緒設計於Weblog介面中以塑造更愉悅的個人化使用經驗等。

　　本研究旨在以使用者需求觀點探討應用「情緒介面」與「自由介面」於Weblog個人化介面設計中，是否能提昇使用者任務操作績效、愉悅性感知、SUS系統使用性、與QUIS使用者介面滿意度。本研究採Eisenhardt (1989)所提出之系統研發方式進行，分為三大階段，第一階段以相關文獻分析結果為基礎，以質性方式分析目前三大代表性Weblog服務Blogger、MSN Space、與Yahoo! 360o，歸納出通用性Weblog介面設計內容；第二階段以問卷與個案訪談方式進行使用者需求調查。第三階段依據文獻探討、現況分析、使用者需求調查結果進行Weblog個人化介面之設計與評估，共設計出四組Weblog測試原型介面供受測者進行一連串任務操作，四組測試原型介面設計分別為：(1) 參考典型Weblog介面設計並結合使用者需求調查之控制組；(2) 加入情緒表達特徵之情緒介面組；(3) 加入可以滑鼠自由移動Weblog介面元件特徵之自由介面組；(4) 結合情緒介面與自由介面元件特徵之情緒+自由介面組。研究結果如下：

(1) 使用者對Weblog功能與個人化介面需求最高的分別是即時預覽以及提供模板或主題。使用者需求調查結果顯示使用者較偏好簡單、明確的設計，同時亦須顧及Weblog「個人特徵之表現」，因此也更顯得當前Weblog個人化介面設計之迫切需要。此外，互動設計師在設計Weblog網站時應格外注意頁面間的流程規劃，避免過多的頁面切換讓使用者迷失於頁面間。

(2) 當前Weblog普及之原因在於其操作流程簡單且介面易於使用，因此顯著影響Weblog典型任務操作時間之因素為受測者之Weblog內容構思時間、文字輸入時間、與網路連線速度等，而非「操作介面時間」。實驗結果亦顯示四組Weblog測試原型介面在整體操作任務績效上無顯著差異存在。

(3) 四組Weblog測試原型介面在愉悅性量表之形容詞「興奮程度」、「滿意程度」、「娛樂程度」、以及「自由程度」上皆有顯著差異存在。由此可知，使用「情緒介面」及「自由介面」設計來協助使用者將其Weblog進行個人化處理，皆可顯著提升使用者在操作Weblog介面時之愉悅感知。

(4) 系統使用性尺度量表(SUS)分析結果顯示，受測者對四組Weblog測試原型介面之系統使用性具有相同主觀評價。此外，就平均數而言，SUS量表總分為100分，而四組Weblog測試原型介面受測者所給予之評量分數皆超過71分，表示四組Weblog測試原型介面設計已具有不錯之使用性。

(5) 四組Weblog測試原型介面在使用者介面滿意度問卷(QUIS)各效標中皆無顯著差異，但中、低兩組Weblog使用經驗在QUIS問卷整體上有顯著差異存在。分析結果顯示，Weblog使用經驗中等的受測者對Weblog的要求最多。

　　經由Weblog介面設計的改良與發展，期望能做為互動設計師在規劃Weblog使用者介面設計之參考依據，幫助使用者可以更容易、更快速、更愉悅、且以更有組織的方式來建構Weblog的個人化呈現。

The service of Weblog can be viewed as a unique media center. It is an open and simple Web tool with the concept of personal on-line publishing system. It is also a newly integrated Web media during these two years. Weblog is slightly changing the current transmission style of Web information, which makes the sharing of information much easier and more effective. By means of the Weblog service, users can quickly establish an on-line personal space. Nonetheless, there are many issues pertaining to the functions and interface design of a Weblog that still need to explore. For example, what are the actual user requirements regarding Weblog functions and interface design? How to avoid resulting in rigid Web information presentation style by providing users with templates? How to incorporate emotion design in the Weblog user interface to facilitate users’ perceptions of more pleasurable interaction experience?

The purpose of this study is to investigate if applying the concepts of “emotion interface” and “user customized interface” can enhance users’ task performance, pleasure perception, system usability and user interface satisfaction based on users’ viewpoints. This research study adopts the methods of system development proposed by Eisenhardt (1989). A total of three stages were used. In the first stage, based on the review of relevant literatures, three represented Weblog service, i.e., Blogger, MSN Space, and Yahoo! 360o, were chosen for qualitative analysis. The common Weblog interface design guidelines were summarized. In the second stage, user requirements were investigated by means of questionnaire survey and interviews of related cases. In the third stage, based on the results generated from literature reviews, current Weblog analysis, and user requirements, personalized Weblog user interfaces were designed and evaluated. A total of four Weblog prototypes were designed for a series of task operations. These four Weblog prototypes were: (1) A typical Weblog user interface with user requirement considerations served as the control group. (2) The emotion group was designed with emotional representation characteristics. (3) The user customized interface group allowed a user to move the Weblog elements freely. (4) The emotion and user customized interface group was designed with the emotion factor and allowed users to freely move the Weblog elements. The results generated from this study were:

(1) What the user requires most regarding Weblog functions and personalized user interface are providing instant preview and templates or topics. The results from user requirement analysis showed that users prefer simple and clear designs with the consideration of presentation of personal characteristics. Because of this, there is an urgent need for personalized user interface design. In addition, an interaction designer needs to carefully plan the interaction flow among different Web pages when designing the Weblog. By so doing can prevent users from disorientation among various Web pages.

(2) The reason why the Weblog is currently so popular is because of its simple interaction process and easy to use. Therefore, the factors of users’ content planning time, time for text input, and Internet speed are the primary factors influencing users’ task performance. The result showed that there existed no significant difference in the users’ over task performance among these four Weblog prototypes.

(3) There existed significant differences in the adjectives of “exciting,” “satisfied,” “pleasurable,” and “free” within the pleasure measurement scale among these four Weblog prototypes. Therefore, the Weblog user interfaces of emotion group and user customized interface group could help users personalize their Weblog design and, at the same time, enhance their pleasure perceptions.

(4) The results from the System Usability Scale (SUS) showed that users had similar subjective assessments towards these four Weblog prototypes. Furthermore, because the total points of the SUS are 100, the points assigned by the users pertaining to these four Weblog prototypes were all higher than 71 points. This means that users were all satisfied with the Weblog usability of these four prototypes.

(5) There existed no significant difference among these four Weblog prototypes pertinent to the results of each evaluation criterion from Questionnaire for User Interaction Satisfaction (QUIS). However, the users of medium- and lower-level use experience revealed significant difference in the overall QUIS survey. The results indicated that users of medium level use experience might have the most strict requirements regarding these four Weblog prototypes.

By means of the refinement and development of Weblog user interface, the author hopes that the research results can be a good reference for interaction designer when s/he plans a Weblog user interface design in the future. Therefore, users can construct and personalize their Weblog user interfaces in a much easier, efficient, pleasurable, and organized way.
