This week we are hosting a speaker from right here at UMD, Dr. Eun Kyoung Choe with a talk about “Designing A Flexible Personal Data Tracking Tool”.


Time: 4/5 (Thursday) from 12:30pm – 1:30pm
Place: HCIL, Room 2105, Hornbake building – south wing
Lunch: BYOL


We now see an increasing number of self-tracking apps and wearable devices. Despite the vast number of available tools, however, it is still challenging for self-trackers to find apps that suit their unique tracking needs, preferences, and commitments. In this talk, I will present OmniTrack, a mobile self-tracking system, which enables self-trackers to construct their own trackers and customize tracking items to meet their individual tracking needs. OmniTrack leverages a semi-automated tracking approach that combines manual and automated tracking methods. From a deployment study, we showed how participants used OmniTrack to create, revise, and appropriate trackers—ranging from a simple mood tracker to a sophisticated daily activity tracker. I will discuss how to further improve OmniTrack by incorporating multimodal interactions, providing more appropriate visualizations on a mobile device, and supporting researchers’ unique data collection needs.


Eun Kyoung Choe ( is an Assistant Professor in the College of Information Studies at University of Maryland, College Park. Her primary research areas are in the fields of Human-Computer Interaction and Health Informatics. She examines the design and evaluation of personal informatics tools to empower individuals—including patients, caregivers, clinicians, and those who wish to engage in self-tracking—to make positive behavior changes through fully leveraging their personal data. She explores this topic in various contexts, including sleep and productivity, patient-clinician communication and data sharing, and personal data insights and visualization. Her past and current research has been funded by the National Science Foundation, Microsoft Research, and the Google Anita Borg Scholarship. She received her PhD in Information Science from University of Washington, MS in Information Management and Systems from University of California, Berkeley, and BS in Industrial Design from KAIST, Korea.
