MoodFlow: Orchestrating Conversations with Emotionally Intelligent Avatars in Mixed Reality (2024)
Presentation / Conference Contribution
Casas, L., Hannah, S., & Mitchell, K. (2024, March). MoodFlow: Orchestrating Conversations with Emotionally Intelligent Avatars in Mixed Reality. Presented at ANIVAE 2024 : 7th IEEE VR Internal Workshop on Animation in Virtual and Augmented Environments, Orlando, Florida

MoodFlow presents a novel approach at the intersection of mixed reality and conversational artificial intelligence for emotionally intelligent avatars. Through a state machine embedded in user prompts, the system decodes emotional nuances, enabling a...

Design Considerations of Voice Articulated Generative AI Virtual Reality Dance Environments (2024)
Presentation / Conference Contribution
Casas, L., Mitchell, K., Tamariz, M., Hannah, S., Sinclair, D., Koniaris, B., & Kennedy, J. (2024, May). Design Considerations of Voice Articulated Generative AI Virtual Reality Dance Environments. Paper presented at SIGCHI GenAI in UGC Workshop, Honolulu, Hawaii

We consider practical and social considerations of collaborating verbally with colleagues and friends, not confined by physical distance, but through seamless networked telepresence to interactively create shared virtual dance environments. In respon... Read More about Design Considerations of Voice Articulated Generative AI Virtual Reality Dance Environments.

Intermediated Reality with an AI 3D Printed Character (2023)
Presentation / Conference Contribution
Casas, L., & Mitchell, K. (2023). Intermediated Reality with an AI 3D Printed Character. In SIGGRAPH '23: ACM SIGGRAPH 2023 Real-Time Live!. https://doi.org/10.1145/3588430.3597251

We introduce live character conversational interactions in Intermediated Reality to bring real-world objects to life in Augmented Reality (AR) and Artificial Intelligence (AI). The AI recognizes live speech and generates short character responses, sy... Read More about Intermediated Reality with an AI 3D Printed Character.

FaceMagic: Real-time Facial Detail Effects on Mobile (2020)
Presentation / Conference Contribution
Casas, L., Li, Y., & Mitchell, K. (2020). FaceMagic: Real-time Facial Detail Effects on Mobile. In SA '20: SIGGRAPH Asia 2020 Technical Communications (1-4). https://doi.org/10.1145/3410700.3425429

We present a novel real-time face detail reconstruction method capable of recovering high quality geometry on consumer mobile devices. Our system firstly uses a morphable model and semantic segmentation of facial parts to achieve robust self-calibrat... Read More about FaceMagic: Real-time Facial Detail Effects on Mobile.

Props Alive: A Framework for Augmented Reality Stop Motion Animation (2020)
Presentation / Conference Contribution
Casas, L., Kosek, M., & Mitchell, K. (2017, March). Props Alive: A Framework for Augmented Reality Stop Motion Animation. Presented at 2017 IEEE 10th Workshop on Software Engineering and Architectures for Realtime Interactive Systems (SEARIS), Los Angeles, CA, USA

Stop motion animation evolved in the early days of cinema with the aim to create an illusion of movement with static puppets posed manually each frame. Current stop motion movies introduced 3D printing processes in order to acquire animations more ac... Read More about Props Alive: A Framework for Augmented Reality Stop Motion Animation.

Intermediated Reality (2019)
Presentation / Conference Contribution
Casas, L. (2019, November). Intermediated Reality. Presented at SA '19: SIGGRAPH Asia 2019, Brisbane, QLD, Australia

This thesis explores technical solutions to address the gap between the virtual and physical worlds towards photo-realistic interactive Augmented Reality (AR). As mobile network bandwidth increases, latencies reduce and graphics processing power beco... Read More about Intermediated Reality.

Multi-reality games: an experience across the entire reality-virtuality continuum (2018)
Presentation / Conference Contribution
Casas, L., Ciccone, L., Çimen, G., Wiedemann, P., Fauconneau, M., Sumner, R. W., & Mitchell, K. (2018, December). Multi-reality games: an experience across the entire reality-virtuality continuum. Presented at the 16th ACM SIGGRAPH International Conference, Tokyo, Japan

Interactive play can take very different forms, from playing with physical board games to fully digital video games. In recent years, new video game paradigms were introduced to connect real-world objects to virtual game characters. However, even the...

Image Based Proximate Shadow Retargeting (2018)
Presentation / Conference Contribution
Casas, L., Fauconneau, M., Kosek, M., Mclister, K., & Mitchell, K. (2018, September). Image Based Proximate Shadow Retargeting. Presented at Computer Graphics & Visual Computing (CGVC) 2018, Swansea University, United Kingdom

We introduce Shadow Retargeting which maps real shadow appearance to virtual shadows given a corresponding deformation of scene geometry, such that appearance is seamlessly maintained. By performing virtual shadow reconstruction from un-occluded real... Read More about Image Based Proximate Shadow Retargeting.
