Redesigning Location-based Check-in App (Daum Place) and Its Interaction Flow

As the primary researcher on redesigning a location-based check-in app Daum Place, I conducted paper prototyping, formative usability testing, and semi-structured interviews to understand the use contexts and specific needs of users of Daum Place and other check-in apps (e.g., Foursquare, Facebook Check-in).

By triangulating the results from studies of different methods , this project identified the Daum Place redesign prototype’s UX problems and provided actionable insights to update the features, interaction flows, and content of this location-based check-in app.

Daum_MapExploring the Needs of Merchants and Users Regarding Local Search and Decision Making

Through focus group interviews and online surveys, this study identified the varied needs of merchants for business listing pages on Daum Place/Map (now Kakao Map) and the decision making process of users/customers for visiting places (e.g., restaurants, coffee shops). This research provided a range of insights for redesigning merchants’ business listing pages and local search results pages on “Daum.net” to meet user needs.

wandering2Wandering as information behavior in new environments

This study examines how international newcomers use “wandering” and geospatial technologies to learn about and interact with their unfamiliar local environments. This is part of my dissertation research and the interviews with a mixed sample of international and domestic newcomer graduate students (57 students in Time 1 and 50 of 57 students in Time 2) were conducted twice over two year period. Geospatial technologies, such as mobile map applications and location-based service applications, facilitated newcomer students’ wandering behavior. By analyzing the findings through the lenses of Wilson’s information seeking behavior models and Erdelez’s information encountering, I characterize newcomer students’ wandering as information seeking behavior and propose new types of information seeking behavior which were identified through this research–active attention and ongoing attention.

Who was a neighbor to those from the other side of the globe?: International newcomer students’ local information behaviors in unfamiliar environments

This research (dissertation) examines international and domestic newcomer students’ information and technology practices and the role that their socio-national contexts play during their adjustment to unfamiliar host environments. Specifically, I developed a theoretical construct “local co-national context” through which I examined the varying information and technology practices of international students from around the world. I used a longitudinal mixed-method approach by conducting online surveys, follow-up semi-structured interviews, and cognitive mapping (a research method in which participants draw their own map of an area; see pictures below) over a two-year period.


Through this longitudinal, mixed method approach, I achieved a holistic characterization of the information behaviors of international newcomer students and identified the social and technological contexts that shape their varying information and technology practices during adjustment to host environments. My dissertation-based article has recently been published in Early View at the Journal of the Association for Information Science and Technology (JASIST).
