The Perceptually-enabled Task Guidance (PTG) program aims to develop artificial intelligence (AI) technologies to help users perform complex physical tasks while making them more versatile by expanding their skillset and more proficient by reducing their errors. PTG seeks to develop methods, techniques, and technology for artificially intelligent assistants that provide just-in-time visual and audio feedback to help with task execution.

Expertise Modeling and User Modeling Research [NSF FW-HTF]

This NSF Future of Work at the Human-Technology Frontier: Core Research project imagines the future of work in precision manufacturing where the spatial and causal reasoning and decision-making abilities of workers on complex production and inspection tasks are augmented through teaming with intelligent extended reality (IXR) technologies.

Real-Time Biometric Data Visualization Tool using High Speed Research Network [DEMO]

This demo project utilize my Empatica E4 Unity plugins to visualize the biometric data in real-time setting. Thanks to the High Speed Research Network (Corelink) that able to support up to 400GB fiber speed, I was able to seamlessly stream the biometric data with a minimal network lag and successfully retrieved the data via remote web server.

Virtual Reality (VR)

Looking Inside Cell VR

Virtual Reality (VR) experience will increase students’ engagement and excitement for STEM learning, bring out their naturally inquisitive natures, and improve their outcomes with these subjects.

BeatPistolSaber VR

This game is a remix of the popular rhythm based VR games: BeatSaber and Pistol Whip that I built to experiment with a simple question of "What if we combine both game mechanics and conduct a playtest protocol.

The Magic Bottle VR: Immersive Multimedia Game in Eye-Tracking in Virtual Reality and Multimodal Biometric Systems [M.S. Thesis, 2020]

Dong Woo Yoo

Virtual reality offers experimentation with human skills beyond what's possible in the real world. The eye gazes instinctively look at the object of interest while the body also responds to it in 3D space. This project aims to explore the relationship between player's engagement vs. physiological data like Blood Volume Pulse (BVP), Interbeat Interval (IBI), Galvanic Skin Response (GSR), and Heart Rate Variability (HRV) using Empatica E4 wristband. I made a simple carnival throwing-style simulation to test the player's engagement and usability. Ultimately, this opportunity led me to create a Unity3D module that retrieve physiological sensing data from the player. This paper explains the process of my design process, prototype phases, and potential implementations.

LEGO Responsible Innovation in Technology for Children (RITEC)

This research explores the question: what does well-being mean to children in a digital age?

As digital technology plays an increasingly important role in children’s development, the Responsible Innovation in Technology for Children (RITEC) project, co-founded with the LEGO Group and funded by the LEGO Foundation, aims to create practical tools for businesses and governments that will empower them to put the well-being of children at the center of digital design.

Zodiac

Zodiac is a learning game that is designed to teach middle and high school students about artificial intelligence concepts. Zodiac supports student learning by providing realistic models that learners can explore and interact with. By acting as an AI Agent that explores a network to collect data, players will learn about artificial intelligence concepts such as search, optimization, and machine learning.

Games

Push

"Push" is a puzzle-solving interactive game, that players can push blocks around in a top-down environment. The player pushes these blocks around to solve various puzzles to progress through the game.
