가상현실(VR) 상호작용 분야의 핵심 미해결 문제—얼마나 왜곡해야 너무 많은 것인가?—에 정면으로 답한 국내 연구가 세계 최고 권위의 VR 학술대회에서 최우수 논문으로 선정됐다.
단국대학교 소프트웨어학과 김하연 교수와 연세대학교 컴퓨터과학과 이인권 교수가 공동 저술한 논문 "How Much Is Too Much? Comfort Envelopes for Distortions in Virtual Reality Interaction"이 오는 3월 21일부터 25일까지 대구 EXCO에서 개최되는 IEEE VR 2026 (IEEE Conference on Virtual Reality and 3D User Interfaces)에서 Best Paper로 선정됐다.
IEEE VR은 가상현실·증강현실·3D 사용자 인터페이스 분야를 대표하는 국제 학술대회로, IEEE Computer Society 및 Visualization and Graphics Technical Committee(VGTC)가 주관한다. 매년 전 세계에서 수백 편의 논문이 제출되며, 그 가운데 엄격한 심사를 통과한 소수의 연구만이 Best Paper로 인정받는다. 올해 대회가 대한민국 대구에서 개최된다는 점에서 국내 연구진의 수상은 더욱 각별한 의미를 갖는다.
이 논문은 VR에서 필연적으로 발생하는 다양한 공간 왜곡—손의 움직임 배율 조정, 순간이동, 시점 재배치 등—이 사용자의 현존감(Presence)과 행위 주체감(Agency)에 미치는 영향을 통합적으로 분석한 연구다. 연구팀은 왜곡을 연속적 메트릭 편차(metric deviations)와 불연속적 위상 단절(topological breaks)의 두 축으로 분류하는 SIDA(Single-Interaction Dual-Axis) 프레임워크를 제안하고, N=52명 참가자를 대상으로 한 정신물리학 실험을 통해 사용자가 각 왜곡 유형을 수용 가능한 한계치, 즉 쾌적 포락선(Comfort Envelope)을 정량화했다. 연구의 핵심 발견은 세 가지다: 연속적 왜곡은 비연속적 왜곡보다 훨씬 높은 관용도를 가지며, 예측 가능한 매핑은 허용 범위를 약 35% 확장시키고, 두 종류의 왜곡은 서로 경쟁하는 방식으로 결합되어 허용 예산을 비선형적으로 제한한다는 것이다. 이 연구는 VR 디자이너들이 그동안 시행착오에 의존해 온 상호작용 왜곡의 허용 한계를 처음으로 원칙적이고 정량적인 방식으로 제시했다는 점에서 의의가 있다.
A joint research team from Dankook University and Yonsei University has won the Best Paper award at IEEE VR 2026 (IEEE Conference on Virtual Reality and 3D User Interfaces), to be held March 21–25 at EXCO in Daegu, Republic of Korea.
The awarded paper, "How Much Is Too Much? Comfort Envelopes for Distortions in Virtual Reality Interaction", was co-authored by Prof. Hayeon Kim (Department of Software Science, Dankook University) and Prof. In-Kwon Lee (Department of Computer Science, Yonsei University).
IEEE VR is the world's foremost academic venue dedicated to virtual reality, augmented reality, and 3D user interfaces, sponsored by the IEEE Computer Society and the IEEE Visualization and Graphics Technical Committee (VGTC). Each year, hundreds of submissions undergo rigorous peer review, and only a small number of exceptional contributions are recognized with the Best Paper distinction. The honor carries additional significance this year as the conference is held in Korea for the first time.

Prof. Hayeon Kim (Dankook Univ) and Prof. In-Kwon Lee has announced that their paper, "Disruption Timing as Information Structure: Collective Recovery in Multi-User Virtual Reality," has been accepted at CHI 2026, the world's premier conference for Human-Computer Interaction (HCI).
In collaborative VR environments, developers often strive for "seamlessness," attempting to hide technical glitches. However, this study uncovers a paradox: concealing failures creates asymmetric awareness among users, which can fracture the shared reality necessary for effective teamwork.
The researchers propose a paradigm shift, treating disruption timing as a deliberate "information structure." Using the theory of Rational Rituals, they introduced the Public, Synchronous, Bounded (PSB) anchor. This design strategy ensures that when a system failure occurs, it happens simultaneously for all users, establishing the "common knowledge" needed for a collective response.
The study, involving 102 participants, demonstrates that fostering a "shared struggle" can be more beneficial for group coordination than maintaining a fragile, individual illusion of seamlessness.
The work will be presented at CHI 2026 in Barcelona, Spain, where experts in XR, UI/UX, and social computing gather to discuss the future of human-technology interaction.

A research team led by Professor In-Kwon Lee at Yonsei University has achieved a remarkable double-header at IEEE VR 2026, the premier international conference for virtual reality. Both papers have been selected for simultaneous publication in the prestigious journal IEEE Transactions on Visualization and Computer Graphics (TVCG).
Study 1: Defining the "Comfort Envelope" for VR Distortions
In the paper "How Much Is Too Much?", Professor Hayeon Kim (Dankook Univ.) and Professor Lee investigate the limits of visual-motor distortions. While VR allows for stretched limbs and rescaled motions, exceeding certain limits breaks the user’s sense of agency and presence. The team introduced the Comfort Envelope, a multi-dimensional budget that guides designers on how much distortion a user can tolerate before the experience collapses. Their study with 52 participants revealed that predictable distortions increase tolerance by 35%, providing a reproducible protocol for future VR interface design.
Study 2: Seamless Walking via Non-Euclidean Portal Resets
The second paper, led by Ho Jung Lee and his colleagues, introduces NEPR (Non-Euclidean Portal Reset), a breakthrough in Redirected Walking (RDW). Traditionally, when a user reaches a physical wall, they must stop and "turn-in-place," breaking immersion. NEPR eliminates this interruption by opening a virtual portal to a non-Euclidean corridor. As the user walks through this short corridor, their physical position is subtly reset without them ever needing to stop. This "continuous walking" approach significantly outperforms traditional resets in both user experience and task efficiency.
These works will be presented at IEEE VR 2026 in Daegu, Korea. By balancing technical innovation with human perception, Professor Lee’s team continues to redefine the boundaries of what is possible in immersive environments.

A research team led by Professor In-Kwon Lee at Yonsei University (Kyumin Kim, Dohae Lee, Hanul Back, and In-Kwon Lee) has achieved a significant milestone with their paper, "RotGS: Rotation-Guided 3D Gaussian Splatting for Turntable Sequences without Structure-from-Motion." The study has been accepted for presentation at Eurographics 2026 and will be simultaneously published in the prestigious Computer Graphics Forum (CGF) journal.
The study tackles a critical bottleneck in 3D reconstruction. While 3D Gaussian Splatting (3DGS) has revolutionized photorealistic scene representation, it traditionally relies on Structure-from-Motion (SfM) to determine precise camera poses—a process that is often unstable in turntable setups. In these environments, background removal reduces reliable feature matches, leading to inaccurate poses and degraded reconstruction quality.
To solve this, the team introduced RotGS, a novel SfM-free method optimized for turntable sequences. By leveraging the geometric prior that objects rotate around a central axis, RotGS simplifies the optimization process using a single global rotation axis.
The work will be presented at the 47th Annual Conference of the European Association for Computer Graphics (Eurographics 2026) in Bonn, Germany. This breakthrough is expected to significantly streamline automated 3D content creation for e-commerce, digital twins, and cultural heritage preservation.

The paper “Manual-Free Gaze Interaction via Bayesian-based Implicit Intention Prediction,” co-authored by Taewoo Jo, Ho Jung Lee, Sulim Chun, and In-Kwon Lee, has been accepted for publication in IEEE Transactions on Visualization and Computer Graphics, a top-tier journal in the field of computer graphics. Previously, when using a user's gaze for pointing and selection, auxiliary means such as hands or controllers were often employed alongside the gaze. This research employs a Bayesian-based method to enhance the probability of correctly determining whether a selection is intended, enabling selection using only the gaze.

Ho Jung Lee has been selected for an Honorable Mention in the 2025 Master’s Thesis Award by the Korean Computer Graphics Society (KCGS). Lee is actively conducting research in the fields of Virtual Reality (VR) and Human-Computer Interaction (HCI), with a particular focus on locomotion techniques that overcome the limitations of physical space—namely, strategies related to Redirected Walking (RDW), such as reset and redirection methods.
He proposed MARR, a reinforcement learning-based resetter that learns optimal reset directions in multi-user environments, and developed the Selective Redirection Controller (SRC), a reinforcement learning model that adaptively applies the most suitable redirection technique based on the user's surrounding environment. In addition, he designed a multimodal reset user interface that combines visual and auditory cues to effectively enhance the user experience.
Based on these research outcomes, Lee authored a total of three papers, all of which were published in IEEE Transactions on Visualization and Computer Graphics (TVCG) and presented at IEEE VR and IEEE ISMAR. One of these papers received the Best Paper Award at IEEE VR 2024.

Hayeon Kim, Jinhyung Park, and In-Kwon Lee's paper ""To Be or Not to Be Me?": Exploration of Self-Similar Effects of Avatars on Social Virtual Reality Experiences" has been accepted for the journal track of the 22nd IEEE International Symposium on Mixed and Augmented Reality (ISMAR) conference. The paper will be presented at the ISMAR 2023 conference in Sydney, Australia, October 16-20, and will be published in the IEEE Transactions on Visualization and Computer Graphics, a top-tier journal in computer graphics. The paper is the first to analyze in-depth the different experiences users have with avatars that are similar to them versus avatars that are not similar to them in a social VR environment. When using self-similar avatars, users experienced a higher sense of embodiment and social presence. On the other hand, presence, an important aspect of the VR experience, was not significantly related to the self-similarity of the avatar. Furthermore, self-similar avatars were found to decrease immersion, another important aspect of the VR experience. This could be due to increased self-awareness, which makes people more cautious of their behavior, which inhibits immersion. In addition, it was found that the voice similarity of the avatar was more important to the VR experience than the visual similarity.
김하연, 박진형, 이인권의 paper "“To Be or Not to Be Me?": Exploration of Self-Similar Effects of Avatars on Social Virtual Reality Experiences” 가 제 22회 IEEE International Symposium on Mixed and Augmented Reality (ISMAR) 학술대회의 저널 트랙에 최종 accept되었다. 이 paper는 오는 2023년 10월 16일부터 20일까지 호주 시드니에서 열리는 ISMAR 2023 학술대회에서 발표되는 동시에 computer graphics분야의 top-tier journal인 IEEE Transactions on Visualization and Computer Graphics에 게재될 예정이다. 이 논문은 social VR 환경에서 사용자와 유사한 아바타와 유사하지 않은 아바타를 사용했을 때 사용자의 다양한 경험을 심도있게 분석한 최초의 연구 결과를 담고 있다. 자기와 유사한 아바타를 사용할 때 사용자는 높은 구체화 (embodiment) 감각과 사회적 존재감을 느낄 수 있었다. 반면에 VR 경험에서 중요한 요소인 현존감 (presence) 은 아바타의 자기 유사성 여부와 큰 상관이 없었다. 게다가 자기 유사 아바타는 VR 경험의 또다른 중요 요소인 몰입감 (immersion) 을 오히려 저하시키는 것으로 나타났다. 이는 자기 인식 (self-awareness) 이 높아지면서, 남들 눈에 비치는 자신의 행동을 조심하게 되며, 이것이 몰입감을 저해하는 것으로 해석된다. 또한 아바타의 자기 유사성 중 비주얼 적인 요소보다는 오히려 음성의 유사성 여부가 VR 경험에 가장 중요한 영향을 미치는 것으로 해석되었다.
