I am a Ph.D. student at the Computer Vision and Geometry Group, ETH Zurich under the supervision of Prof. Marc Pollefeys. My research interests are Action Recognition, Video Understanding, Egocentric Vision, 3D Vision, Hand-object Interaction, Multi-modal Learning, AR/VR and Computer Vision. Previously, at UCLA, I graduated with an M.S. in Electrical and Computer Engineering. Also, I received my B.S. in Electrical Engineering from Yonsei University, Seoul, Korea I will finish my PhD this coming winter and I am actively looking for research positions. |

Xin Wang*, Taein Kwon*, Mahdi Rad, Bowen Pan, Ishani Chakraborty, Sean Andrist, Ashley Fanello, Bugra Tekin, Felipe Vieira Frujeri, Neel Joshi, Marc Pollefeys ICCV, 2023 project page HoloAssist is a large-scale egocentric human interaction dataset, where two people collaboratively complete physical manipulation tasks. By augmenting the data with action and conversational annotations and observing the rich behaviors of various participants, we present key insights into how human assistants correct mistakes, intervene in the task completion procedure, and ground their instructions to the environment. * indicates equal contribution |

Junan Lin*, Zhichao Sun*, Enjie Cao*, Taein Kwon, Mahdi Rad, Marc Pollefeys arXiv, 2023 paper Contact-aware Skeletal Action Recognition (CaSAR) uses novel representations of hand-object interaction that encompass spatial information: 1) contact points where the hand joints meet the objects, 2) distant points where the hand joints are far away from the object and nearly not involved in the current action. Our framework is able to learn how the hands touch or stay away from the objects for each frame of the action sequence, and use this information to predict the action class. * indicates equal contribution |

Siwei Zhang, Qianli Ma, Yan Zhang, Zhiyin Qian, Taein Kwon, Marc Pollefeys, Federica Bogo, Siyu Tang ECCV, 2022 project page / paper / code EgoBody is a large-scale dataset of accurate 3D human body shape, pose and motion of humans interacting in 3D scenes, with multi-modal streams from third-person and egocentric views, captured by Azure Kinects and a HoloLens2. Given two interacting subjects, we leverage a lightweight multi-camera rig to reconstruct their 3D shape and pose over time. |

Taein Kwon, Bugra Tekin, Siyu Tang, Marc Pollefeys CVPR, 2022 (Oral Presentation) project page / paper / video / code We propose a skeletal self-supervised learning approach that uses alignment as a pretext task. Our approach to alignment relies on a context-aware attention model that incorporates spatial and temporal context within and across sequences and a contrastive learning formulation that relies on 4D skeletal augmentations. Pose data provides a valuable cue for alignment and downstream tasks, such as phase classification and phase progression, as it is robust to different camera angles and changes in the background, while being efficient for real-time processing. |

Taein Kwon, Bugra Tekin, Jan Stuhmer, Federica Bogo, Marc Pollefeys ICCV, 2021 project page / paper / video In this paper, we propose a method to collect a dataset of two hands manipulating objects for first person interaction recognition. We provide a rich set of annotations including action labels, object classes, 3D left & right hand poses, 6D object poses, camera poses and scene point clouds. We further propose the first method to jointly recognize the 3D poses of two hands manipulating objects and a novel topology-aware graph convolutional network for recognizing hand-object interactions. |

Taein Kwon, Eunjeong Park, Hyukjae Chang ACM BCB, 2016 We propose a sensor-equipped food container, Smart Refrigerator, which recognizes foods and monitors their status. We demonstrated the performance in detection of food and suggested that automatic monitoring of food intake can provide intuitive feedback to users. |
