Introduction
Hi, I'm Hyeok Kim (hjʌk). I'm a PhD candidate in Computer Science at Northwestern University. Currently, I work with Professor Jessica Hullman at MU Collective. Previously, I did my masters in Communication at Seoul National University with colleagues from HCI+D Lab.
My research interests include
- 📊 data visualization,
- 📱🖥 responsive visualization and multi-context visualization
- 🛠 visualization system, formalization, and automation,
- 📜 narrative and communicative visualization, and
- 🧙🏻♂design research for societal problems.
If you are interested in these areas as well, feel free to contact me for collaboration 🙆🏻♂!
More background
I studied Linguistics for my undergraduate major, and Computational and Statistical Linguistics for my student-designed minor. Data visualization was my way to practice programming and statistics together—this was indeed a great approach and led me to various areas in HCI, including system design, visualization grammar, and design research. I am a first-generation PhD student.
Research
I have led exciting research projects that are close to the domain fields and published papers on data visualization and design research in top HCI venues.
Responsive Visualization Authoring
Data visualization helps us to reason about various problems from daily decisions to professional judgment. We face more and more visualization use cases through diverse device types (mobile phones, desktops). To enable seamless support for visualizations on different devices, I have studied "responsive visualization," referring to adapting visualizations for different device types.
Authoring responsive visualizations is not easy because it is hard to manage multiple versions and every individual creators have a full set of relevant knowledge. Thus, I took a "mixed-initiative" (= automated recommendation + human customization) approach to support responsive visualization authoring. This took an extensive path: understanding current practices and tradeoffs, formalizing loss measures for preserving task-oriented insights between responsive versions, formalizing responsive transformations (Cicero grammar), and an interface for mixed-initiative responsive visualization authoring.

Design for Societal Problems
Designing for the underrepresented helps us to grow better as a community. My interest is bridging what underrepresented groups need to how a system—beyond user interface—is designed, implemented, and deployed.
Information System for Sexual Violence Survivors
Sexual violence survivors often have a hard time finding suitable support services due to various societal and personal constraints. While personalization is key to navigating a vast search space of support-seeking, how to personalize (i.e., how to ask for personalization and how to provide personalized information) has been less asked given its importance. To understand personalization in a conversational interaction setting, we conducted a co-design workshop with experts, implemented a high-fidelity prototype system, and interviewed self-identified sexual violence survivors.

Design Guidelines for the In-game Sexual Harassment Prevention System
In online video games, sexual harassment against female gamers frequently occurs and becomes worse with various factors. This research project attempts to suggest design guidelines that both prevent harassment. A short paper on this project was published in HCI Korea 2018 Conference (extended abstract).

Media-as-Place Storytelling
From escape rooms to Sara is Missing... and Searching..., we experience a new kind of narrative where their places seem identical to their media: real objects in escape rooms, a smartphone for Sara is Missing..., and a computer for Searching.... We shed light on this emerging storytelling technique by identifying it as 'Media-as-Place' storytelling. This approach will enhance place-based learning of HCI as well as enrich our digital narrative techniques.
The implementation of MiRO, a Media-as-Place computer game
This game demonstrates the idea of Media-as-Place storytelling. This work was presented at DIS 2019 Work-in-Progress track.
