Instagram標題文字大小閱讀舒適性之研究

The Study of Title Fonts Sizes on Instagram for Reading Comfort

對於長時間使用移動型裝置的社群使用者，當使用的頻率愈來愈高時，不舒服的的字體大小可能會造成消極的使用體驗，最終導致使用者對該社群頻道之評價不佳，甚至停止追蹤、閱覽。本研究旨在探討懶人包類型之社群貼文使用不同字體設計的介面設計與閱讀舒適性與美感之間的關係，進行內容分析法與實驗設計方法，所蒐集資料採雙因子變異數分析，透過立意抽樣的方法共招募79位受試者參與。實驗結果發現：（1）字體越大對於閱讀舒適性之評估較具有良好的接受度；（2）閱讀舒適性與美感交互作用成正相關；（3）設計師以使用者角度觀看字體大小之閱讀舒適性與美感時，並不會因自身設計背景與一般人有太大的差異；（4）與文獻提出之三種常見小螢幕字體大小偏好結果相異。本研究成果可作為移動型裝置上之社群貼文介面設計實務上的參考依據。

Social media posts have become the main entry point for users to obtain information resources; therefore, the inappropriate fonts size may make the user experience negative as the frequency of use increases, and eventually lead to the users' poor experience of the channel and even stop tracking and reading. This study conducted content analysis and experimentation approach aimed to investigate the relationship between user interface design of aggregated information title on Instagram with reading comfort and aesthetics of different font sizes. The results revealed that (1) The larger the font, the higher the acceptance of the reading comfort assessment. (2) The interaction between reading comfort and aesthetics is positively correlated. (3) When the designer looks at the reading comfort and aesthetics of the font size from the user's point of view, it does not differ too much from the average because of his or her design background. (4) The results are different from the three types of common font size preferences for small displays presented in the literature. The results of this study can be used as a practical reference for interface design on mobile devices.
