Research Expertise

Description

Creating virtual replicas of human beings, in both appearance and motion, is one of the greatest challenges in the field of Computer Graphics and beyond. My main research direction involves advancing the state-of-the-art in virtual humans, a highly competitive field with large investment from the top tech companies (Microsoft, Google, Meta, etc.). However, I am credited with a unique approach of using human perception to deepen our understanding of virtual humans and improve the technological advancements. I have made a significant impact by exploring the use of novel experiments to understand human perception of virtual beings. In particular, how photorealism can influence higher level concepts such as perceived emotion, personality, and trustworthiness. My work has been published at the top venues (including ACM TOG, TOCHI, TAP, CGF, CAG, IEEE VR, ISMAR, IVA, MIG, SAP since my last promotion) and I secured >€2.5M in research funding (€1.3M since my last promotion). I am a recognised world leader in virtual human research, as evidenced by an industry award of $85K from Epic Games, to collaborate on using perception to improve their high-fidelity 'Metahumans'. I also gave masterclasses on perception of virtual humans at Eurographics (Tutorial, 2020) and SIGGRAPH (Course, 2019). I am also a leader in embodied virtual human research, and credited as the first to use adversarial networks for automating the gesture behaviours of virtual agents. Our system is recognised as one of the current leading systems in AI gesture generation (cited 55 times since 2020). I have also been awarded funding from EI to investigate commercial feasibility and was invited as a leading expert to co-author a chapter in the ACM Handbook on Socially Interactive Agents. Finally, our Trinity-Speech-Gesture dataset was licensed to Electronic Arts Inc., who recognised the dataset as the gold-standard for speech-to-gesture systems.

Projects

  • Title
    • RADICal: on-set virtual Reality for Actors portraying DIgital Characters
  • Summary
    • The main aim of this project will be to transform the traditional approaches for face and body capture of film actors, using real-time motion capture and Virtual Reality (VR) to allow them to visualize their virtual faces and bodies from a first-person perspective, live on-set. We hypothesize that this will greatly enhance their performances and overall satisfaction in playing the role of a virtual character. The main novelty of our approach is incorporating actor methods and practices into the technical algorithms for motion tracking and mapping and conducting neuroscience experiments to enhance the illusory perception that a virtual body or body-part is the actors own.

  • Title
    • Game Face: Perceptually Optimised Real-Time Facial Animation
  • Summary
    • The main aim of this project will be to transform the typical facial animation pipeline used for games, by considering user perception at each of the steps from motion capture and expression transfer to deformation, and real-time display. Our result will be a perceptually optimised pipeline that will balance computation with realism, plausibility, and emotional expressiveness of virtual facial animation.

  • Title
    • Cartoon Motion: Stylised facial animation from motion capture
  • Summary
    • A skilled 3D animator can create the same expressiveness in virtual characters that is commonly found in traditional animation. However, this process can be very time consuming and expensive. In this novel project, we aim to address this issue by developing tools to automatically create motion that captures the idiosyncrasies of the human actor, yet incorporates artistic stylizations.
