Expressive Talking Avatars (2024)
Journal Article
Pan, Y., Tan, S., Cheng, S., Lin, Q., Zeng, Z., & Mitchell, K. (2024). Expressive Talking Avatars. IEEE Transactions on Visualization and Computer Graphics, 30(5), 2538-2548. https://doi.org/10.1109/TVCG.2024.3372047

Stylized avatars are common virtual representations used in VR to support interaction and communication between remote collaborators. However, explicit expressions are notoriously difficult to create, mainly because most current methods rely on geome... Read More about Expressive Talking Avatars.

Editorial: Games May Host the First Rightful AI Citizens (2023)
Journal Article
Mitchell, K. (2023). Editorial: Games May Host the First Rightful AI Citizens. Games: Research and Practice, 1(2), 1-7. https://doi.org/10.1145/3606834

GAMES creatively take place in imaginative worlds informed by, but often not limited by, real-world challenges, and this advantageously provides an accelerated environment for innovation, where concepts and ideas can be explored unencumbered by physi...

Games Futures I (2023)
Journal Article
Deterding, S., Mitchell, K., Kowert, R., & King, B. (2023). Games Futures I. Games: Research and Practice, 1(1), Article 5. https://doi.org/10.1145/3585394

Games Futures collect short opinion pieces by industry and research veterans and new voices envisioning possible and desirable futures and needs for games and playable media. This inaugural series features eight of over thirty pieces.

Inaugural Editorial: A Lighthouse for Games and Playable Media (2023)
Journal Article
Deterding, S., Mitchell, K., Kowert, R., & King, B. (2023). Inaugural Editorial: A Lighthouse for Games and Playable Media. Games: Research and Practice, 1(1), Article 1. https://doi.org/10.1145/3585393

In games and playable media, almost nothing is as it was at the turn of the millennium. Digital and analog games have exploded in reach, diversity, and relevance. Digital platforms and globalisation have shifted and fragmented their centres of gravit... Read More about Inaugural Editorial: A Lighthouse for Games and Playable Media.

Emotional Voice Puppetry (2023)
Journal Article
Pan, Y., Zhang, R., Cheng, S., Tan, S., Ding, Y., Mitchell, K., & Yang, X. (2023). Emotional Voice Puppetry. IEEE Transactions on Visualization and Computer Graphics, 29(5), 2527-2535. https://doi.org/10.1109/tvcg.2023.3247101

The paper presents emotional voice puppetry, an audio-based facial animation approach to portray characters with vivid emotional changes. The lips motion and the surrounding facial areas are controlled by the contents of the audio, and the facial dyn... Read More about Emotional Voice Puppetry.

Collimated Whole Volume Light Scattering in Homogeneous Finite Media (2022)
Journal Article
Velinov, Z., & Mitchell, K. (2023). Collimated Whole Volume Light Scattering in Homogeneous Finite Media. IEEE Transactions on Visualization and Computer Graphics, 29(7), 3145-3157. https://doi.org/10.1109/TVCG.2021.3135764

Crepuscular rays form when light encounters an optically thick or opaque medium which masks out portions of the visible scene. Real-time applications commonly estimate this phenomena by connecting paths between light sources and the camera after a si...

Improving VIP viewer Gaze Estimation and Engagement Using Adaptive Dynamic Anamorphosis (2020)
Journal Article
Pan, Y., & Mitchell, K. (2021). Improving VIP viewer Gaze Estimation and Engagement Using Adaptive Dynamic Anamorphosis. International Journal of Human-Computer Studies, 147, Article 102563. https://doi.org/10.1016/j.ijhcs.2020.102563

Anamorphosis for 2D displays can provide viewer centric perspective viewing, enabling 3D appearance, eye contact and engagement, by adapting dynamically in real time to a single moving viewer’s viewpoint, but at the cost of distorted viewing for othe...

Active Learning for Interactive Audio-Animatronic Performance Design (2020)
Journal Article
Castellon, J., Bächer, M., McCrory, M., Ayala, A., Stolarz, J., & Mitchell, K. (2020). Active Learning for Interactive Audio-Animatronic Performance Design. The Journal of Computer Graphics Techniques, 9(3), 1-19

We present a practical neural computational approach for interactive design of Audio-Animatronic® facial performances. An offline quasi-static reference simulation, driven by a coupled mechanical assembly, accurately predicts hyperelastic skin deform...

Intermediated Reality: A Framework for Communication Through Tele-Puppetry (2019)
Journal Article
Casas, L., & Mitchell, K. (2019). Intermediated Reality: A Framework for Communication Through Tele-Puppetry. Frontiers in Robotics and AI, 6, https://doi.org/10.3389/frobt.2019.00060

We introduce Intermediated Reality (IR), a framework for intermediated communication enabling collaboration through remote possession of entities (e.g., toys) that come to life in mobile Mediated Reality (MR). As part of a two-way conversation, each... Read More about Intermediated Reality: A Framework for Communication Through Tele-Puppetry.
