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.
