I am primarily interested in understanding the effects of different kinds of shared information in the group activities, and supporting information sharing tasks that improve the activities. For instance, I designed a new way of displaying exchanged messages in an instant messaging environment , a navigation mechanism to organize shared group documents based on their location-related information , and a virtual group workspace to arrange the shared documents and rationales according to a design case structure . Nonetheless, my main research focus involves examining the role of shared rationales in the group ideation and deliberation activities, and exploring design guidelines to support members to articulate, share, and reuse the rationales. I define “rationale” as the information that provides justification of one’s ideas, approach, and solution in group activities.

My secondary research interests include socio-technical design to support informal learning activities that involve parents and their child/children. We conducted a conceptual analysis of design requirements for supporting parent-small children interactions in interactive tabletop apps. (Xiao & Martin, 2012). I am currently leading an informal learning workshop project that invites parents and children to engage in math learning and math game design activities.

Two other research areas that I have started to explore are digital humanities and visual analytics. I have been taking a participatory design approach in developing a digital environment that offers visual analytics tools along with others to contribute to human rights remembrance, education, and research. Our first visual analytics prototype is available at YouTube, http://www.youtube.com/watch?v=5Yy1xCjC-Hk.
