Look me in the eyes: A survey of eye and gaze animation for virtual agents and artificial systems

International audienceA person's emotions and state of mind are apparent in their face and eyes. As a Latin proverb states: "The face is the portrait of the mind; the eyes, its informers.". This presents a huge challenge for computer graphics researchers in the generation of artificial entities that aim to replicate the movement and appearance of the human eye, which is so important in human-human interactions. This State of the Art Report provides an overview of the efforts made on tackling this challenging task. As with many topics in Computer Graphics, a cross-disciplinary approach is required to fully understand the workings of the eye in the transmission of information to the user. We discuss the movement of the eyeballs, eyelids, and the head from a physiological perspective and how these movements can be modelled, rendered and animated in computer graphics applications. Further, we present recent research from psychology and sociology that seeks to understand higher level behaviours, such as attention and eye-gaze, during the expression of emotion or during conversation, and how they are synthesised in Computer Graphics and Robotics

LibViz: a visualisation toolkit to support the preservation of the Old Library

The Graphics, Vision and Visualisation (GV2) group in TCD\u27s School of Computer Science and Statistics is working with the Preservation and Conservation Department of the Library, to develop a fully interactive 3-D model of the Old Library, known as the LibViz. LibViz demonstrates a significant innovation in the approach to the study of a single building. The research project is developing a system to visualise structural and environmental data relating to the Old Library. This includes visualising dust dispersion levels, temperature and relative humidity levels and the condition of structural elements, within an accurate to-scale recreation of the building and its key features. The model will also be used to document the impact of changes once a remediation plan is commenced
