Towards Mocap Anywhere: Pairwise Distance-based Motion Capture in the Wild, for the Wild

Ofir Abramovich, Ariel Shamir, Andreas Aristidou

ACM Transaction on Graphics, Aug 2026

We introduce Wild-Poser (WiP), a real-time Transformer-based system that reconstructs full-body 3D motion from sparse pairwise distance measurements using body-mounted UWB sensors, without cameras or environmental constraints. WiP robustly predicts accurate 3D joint positions from noisy data and generalizes across diverse human and non-human morphologies in real-world settings.

Cross-Morphology Motion Transfer with Semantic Style Alignment

Alexios Mylordos, Jose Luis Ponton, Nuria Pelechano, Andreas Aristidou

IEEE Transactions on Visualization and Computer Graphics, Aug 2026

In this work, we present a neural framework for cross-morphology motion transfer that enables realistic animation retargeting across characters with diverse skeletal structures. By using morphology-agnostic control signals and morphology-specific latent codebooks, our method preserves both the semantic intent of the source motion and the natural style of the target character. We demonstrate accurate and scalable all-to-all retargeting across bipeds and quadrupeds, with optional user control for fine-grained motion editing.

MultiAct: Text-to-Motion Generation from Composite Text via Tailored Attention Guidance

Nathan Sala, Ofir Abramovich, Ariel Shamir, Daniel Cohen-Or, Andreas Aristidou, Sigal Raab

Proceedings of the Special Interest Group on Computer Graphics and Interactive Techniques Conference, Conference Papers, Jul 2026

Presented at: SIGGRAPH Conference Papers '26

We introduce MultiAct, an inference-time method that enhances pretrained text-to-motion models to better capture multiple simultaneous actions. By adaptively boosting attention to underrepresented prompt components, it improves semantic completeness without retraining, achieving stronger results on complex prompts.

MotionPyramid: Controllable Motion Synthesis via Stylized Phase Manifolds

Jingyuan Li, Peizhuo Li, Andreas Aristidou, Olga Sorkine-Hornung

Computer Graphics Forum, Volume 45, Issue 8., Jul 2026

Presented at: 25th ACM SIGGRAPH/ Eurographics Symposium on Computer Animation, SCA'26, Barcelona, Spain

MotionPyramid introduces stylized phase manifolds, a compact and interpretable latent representation that disentangles motion semantics, temporal dynamics, and style in an unsupervised, low-dimensional space. By using this representation as a structured bridge between text and motion, MotionPyramid enables fine-grained control over diffusion-based motion generation, producing high-quality, diverse motions with improved text-to-motion alignment.

Latent Space Skinning: Learning Compact Representations for Mesh Animations

Giorgos Drongoulas, Grigoris Tsopouridis, Andreas Aristidou, Ioannis Fudos

Presented at: 25th ACM SIGGRAPH/ Eurographics Symposium on Computer Animation - Posters, SCA'26. Eurographics Association, Jul 2026

Latent-Space Skinning (LSS) is a neural character animation framework that replaces explicit skinning weights with a shared latent representation of skeletal motion and rest-pose geometry, which is decoded into per-vertex mesh deformations over time. This compact and expressive latent space enables high compression ratios, accurate reconstruction, and intuitive motion manipulation operations such as blending and cross-character transfer.

Mixed Reality in Electronic Health Records: User Requirements and Evaluation

Silouanos Chaldoupis, Eirini Schizas, Andreas Aristidou

Presented at: 39th IEEE International Symposium on Computer-Based Medical Systems, CBMS 2026, Limassol, Cyprus, Jun 2026

We present an MR-enhanced Electronic Health Record system that enables intuitive exploration of multimodal patient data through spatial, holographic interfaces. Our approach integrates clinical information, including 3D medical imaging, into an interactive mixed reality environment, demonstrating improved usability, anatomical understanding, and support for collaborative and patient-centered care.

Sound Sparks Motion: Audio and Text Tuning for Video Editing

AmirHossein Naghi Razlighi, Aryan Mikaeili, Ali Mahdavi-Amiri, Daniel Cohen-Or, Yiorgos Chrysanthou

arXiv preprint arXiv:2605.15307, May 2026

This paper presents Sound Sparks Motion, a training-free framework for motion-centric video editing that enables localized action and state-transition modifications in existing videos by tuning multimodal conditioning signals of an audio-visual video generation model at test time. By optimizing only an audio latent and a text-conditioning residual using vision-language feedback, the method achieves effective motion editing while preserving visual content and quality, and demonstrates that the learned controls can transfer across videos as reusable motion-edit directions.

Savvas Zotos, Marilena Stamatiou, Sofia-Zacharenia Marketaki, Duncan J. Irschick, Jeremy A. Bot, Andreas Aristidou, Emily L. C. Shepard, Mark D. Holton, Ioannis N. Vogiatzakis

Integrative Zoology, Volume21, Issue3, Pages 468-484, May 2026

This paper introduces a multidisciplinary approach to studying reptile behavior, combining tri-axial accelerometers, video recordings, motion capture systems, and 3D reconstruction to create detailed digital archives of movements and behaviors. Using two Mediterranean reptiles as case studies, it highlights the potential of this method to advance research on complex and understudied behaviors, offering ecological insights and tools for behavioral analysis.

Interactive Engineering Training Framework in Mixed Reality Environments

Christina-Georgia Serghides, Andreas Aristidou

Presented at: International Workshop on eXtended Reality for Industrial and Occupational Supports (XRIOS), part of IEEE VR 2026 conference, Daegu, Korea,, Mar 2026

We present a Mixed Reality–based framework for collaborative engineering training in aerospace and automotive maintenance and assembly, addressing the complexity, safety, and procedural demands of traditional hands-on methods. By building on existing computer-based and VR/AR approaches, the proposed platform bridges the gap between physical training and digital solutions, enabling more efficient, cost-effective, and collaborative training experiences.

CrowdImprint: decomposing context-aware interactions

Marilena Lemonari, Panayiotis Charalambous, Julien Pettré, Yiorgos Chrysanthou

The Visual Computer, 42(128), Jan 2026

We present a model that learns how people interact with specific objects or “sources” by analyzing trajectories, decomposing movements into simple core behaviours (e.g., approach, stop, circle). It builds distributions of these behaviours to summarise and generate context-aware crowd interactions, demonstrating usefulness for tasks like behaviour comparison.
