An Evaluation Approach for a Physically-Based Sticky Lip Model - Computers
Following the CGVC 2018 conference, my paper was selected as one of the best papers and I was invited to submit an extended version for journal publication in the Computers journal. The paper was peer-reviewed and accepted for publication. The paper presents the inital work on an evaluation method for mouth models, presenting a novel set of metrics and method for tracking the inner lip contour. The metrics can be tracked over time and the resulting profiles used to compare animations with real mouths. This work forms part of my PhD work.
Recreating Sheffield’s Medieval Castle In Situ using Outdoor Augmented Reality - EuroVR 2018
This paper was the result of a 5 month project which was undertaken during a leave of absence from my PhD. The work looked at generating an augmented reality version of the former Sheffield Castle, which could be viewed in its original location as if it stood there today amongst the existing buildings.
Physically-based Sticky Lips - Computer Graphics & Visual Computing 2018
This paper was accepted to the Computer Graphics & Visual Computing 2018 conference. The paper presents work on producing a physically-based animation of the mouth using the finite element method. The model implements a novel stickiness model, simulating the effect of the saliva between the lips. The model is capable of reproducing a set of behaviours observed in real mouths, such as "zippering", formation of multiple mouth openings and the formation of asymmetric mouth openings. This work forms part of my PhD work.

A mouth speaking the word mummy in slow motion. On the left, sticky elements are not re-instantiated, leading to intersection of the lips when it closes in the middle of the animation, and no stickiness behaviour when opening the second time. On the right, saliva elements are reinstantiated as the mouth closes, providing contact handling and sticky behaviour on the second opening.
