本文乃一跨領域研究， 團隊試圖將資訊科學工具， 導入 Facebook 打卡研究之中，作為輔助質性研究的一項利器。我們先 以de Certeau 與Lefebvre 概念為本，勾勒一操作架構，作為開發視 覺化行人言說分析工具VPSA（visualized pedestrian speech acts application for Facebook check-in）之基礎，接著以此工具進行質 性個人化打卡實踐分析，並將分析結果與大數據之打卡統計進行對 話，最終反身性思考液態社會時期的方法議題。

In this interdisciplinary study, we apply technologies developed in computer science to research on Facebook check-in practices. The objective of our work is to create a new tool to facilitate qualitative research on everyday life practices. We first use concepts proposed by de Certeau and Lefebvre to sketch an operational scheme, which serves as a basis for the design of our visualization analysis tool called visualized pedestrian speech Acts application for Facebook check-in (VPSA). We then use the tool to analyze the check-in practices of various individuals and to enable feedback between qualitative analysis and statistical data on check-in behaviors. Finally, on the basis of our research experience, we reflect on the need for new research methodologies in the modern era.
