中高齡者部落格之影音介面研究
A Study on the Video User Interface of Blogs for People at Middle Age
摘要
隨著生活水準的提高及醫療衛生的進步，中高齡人口比例日漸增加。由於生理衰退、缺乏社交活動的緣故，需協助其提高生活上的滿足感，並規劃未來的退休生活。部落格提供了抒發情感的空間，透過分享日誌、照片、影片來交換生活經驗。另外，經由不同部落格間的連結，可讓使用者更容易找到與自己擁有相同經驗及興趣的人，並透過部落格吸收新的資訊。然而，現今部落格的環境並未考量中高齡者的限制，操作複雜的使用者介面及過多的資訊，可能會降低其使用的興趣。 本研究目標在探討中高齡者部落格之影音介面。首先，先期研究以典型的部落格平台為例，調查中高齡者對部落格功能之需求，結果顯示「影音分享」功能之需求性最高。接著針對部落格之上傳、分享及影片播放介面，設計兩套實驗網頁，並與現有部落格「天空部落」進行比較，受測者分為三組執行實驗任務。實驗後以單因子變異數分析三套網頁在主觀及客觀評量是否有顯著差異。 研究結果顯示：（1）上傳檔案以拖曳的方式較佳。（2）播放介面部分：播放螢幕中應有播放提示的功能；暫停鍵與播放鍵應各自獨立；時間軸應包含快轉、倒轉鍵並搭配關鍵影格圖片；音量控制以點擊較細微的拖曳動作為佳；控制列置於整個螢幕的下方較佳。（3）分享介面應加入好友名單功能；若能在分享目標上作點選以則不需要核取方塊。

With the improvement of living standard and the progress of the health-care technologies, the proportion of people at middle age increases day by day. Due to declining physiological condition and lacking of social interactions, these people may need helps from others to improve their satisfaction in everyday life and plan or retirement in the future. Weblog tools offer the platform for people to express their emotion and exchange their experience by sharing diaries, photos, and film. In addition, through the links among different Blogs, it is easier for participants to find people of similiar experience and interest, and therefore absorb new information through Blogs. However, current Blog tools do not consider the limitation of people at middle age. The complexity of user interfaces hampers their willingness to use such tools. Therefore, the objective of this study was to investigate the user interface of Blog tools for middle-age people. First, the author conducted a pilot study on typical hosting sites to elicit functional demands for blogging. The result showed that “video sharing” was the most desirable function. Second, the author designed two experiment web sites for the user interfaces of uploading, sharing, and broadcasting video files, and then compared them with an existing blog, Yam Blog. Furthermore, participants in three groups performed typical tacks during the experiments. After the experiments, one-way analysis of variance ANOVA was used to analyze whether three web sites had significant differences either in the performance of subject or subjective evaluation. The results are summarized as follows: (1) It is better to upload the file by way of dragging. (2) The broadcasting interfaces should have the function of broadcast prompt in the screen. (3) The pause button and play button should be independent. (4) The timeline control should include forward and backward functions and key frames for pictures of selection. (5) Clicking on the scroll bar is better than the slight movements of dragging for volume controls. (6) The location of the control toolbar should be at the lower part of the screen. (7) Friend list is necessary in the sharing interface. (8) Check box is not necessary if the selection of sharing targets can be activated by clicking on the control area. These results can serve as the guidelines for user interface design.
