Research Objective

In my research, I am reimagining the space of online interaction with safety and inclusivity as my top priorities. Drawing on techniques from visualization, user-interface design, and social computing, I plan to develop tools for moderators, investigate effective moderation strategies, and explore the design space of online social interactions. I hope to impact the design of future platforms and make online safety tools that can be deployed directly to the user. My current project is ConvEx: a visualization based approach to putting state-of-the-art text analysis algorithms in the hands of moderators.

3D Hand Pose Estimation on Conventional Capacitive Touchscreens

MobileHCI ‘21

Frederick Choi, Chris Harrison, Sven Meyer

Research Experience

• Advised by Dr. Eshwar Chandrasekharan
• Applying visualization techniques to incorporate state-of-the-art text analysis algorithms (e.g. Perspective API for toxicity) into a tool for moderators on Discord
• Currently evaluating the efficacy of visualizing toxicity with ConvEx in helping moderators to identify patterns of behavior and and take proactive measures

• Advised by Dr. Chris Harrison
• Developed software that can take capacitive touch data from a multi-touch screen (such as an iPad) and construct a 3D hand model of the user’s hand pose, enabling rich interaction possibilities using pre-existing hardware
• Published in MobileHCI ‘21 (see Publications)

• Group led by Dr. Ron Eglash
• Supervised by James Davis
• Created culturally-aware interactive software with the goal of better engaging primary and secondary students of underrepresented demographics and fostering in them a deeper interest in STEM
• Recreated (as a web application) Rhythm Wheels, a CSDT application which embedded concepts involving GCD, LCM, and modular arithmetic into a fun and musical experience.
• Presented at the 9th Annual Undergraduate Research Symposium at RPI and won an award (see Awards/Achievements)

• Extracurricular high school research project
• Advised by Dr. Thomas Banchoff, professor emeritus at Brown University
• Created interactive illustrations of mathematics that can easily be embedded in a web article or journal
• Intended for teachers and authors to help students and readers visualize concepts in order to build a good geometric intuition that is foundational to learning mathematics
• Written in TypeScript with three.js

Professional Experience

• Supervised by Charles McKenzie
• Built new features and contributed to the web interface for Wayfair credit card and financing options
• Worked with full stack technologies (PHP, JavaScript, CSS, Git, etc.)

Teaching Experience

• Holding office hours
• Answering student questions, clarifying the lecture material and helping students understand abstract concepts (e.g., right-hand rule for surface normals) in a concrete way (e.g., drawing a picture)

• Assisted in conducting labs
• Explain the tasks and help students understand the concepts it implements, including pointers, arrays, data structures, etc.

• Assisted in office hours
• Helped students learn the fundamentals of computer science, such as variables, functions, classes, etc.
