Dr. John Dingliana

Assistant Professor (Computer Science)

Dr. John Dingliana graduated with a B.Sc. Honors degree in Computer Science from University College Dublin in 1998 and received his PhD in the Department of Computer Science, Trinity College Dublin in 2003. His PhD thesis was titled Adaptive Levels of Detail for Interactive Collision Handling. He was appointed as a Lecturer in Computer Science from 2000-2002 and Research Fellow in the Interaction Simulation and Graphics group, TCD from 2002-2005. Since July 2005 he is an Assistant Professor in the School of Computer Science and Statistics, Trinity College Dublin. His main research interests are in real-time computer graphics, interactive visualisation and augmented and virtual reality.

My research lies in the fields of Computer Graphics and Visualization, specifically areas including animation, rendering, perceptually-adaptive techniques, visualization, stylised images and Augmented & Virtual Reality. The consistent thread in my research is the question of how information is optimally conveyed through visual digital media, in the context of increasing complexity of data, evolving display technologies and their widening uptake in user domains beyond those traditionally associated with computer graphics. Recent technological advances have vastly increased the scale of digital data that we process on an everyday basis, while graphics technology has reached levels fidelity that match perceptual limits of the human visual system. This raises many new challenges but also opportunities for furthering human consumption of data and enriching visual applications. I investigate how the most important aspects of static, dynamic and interactive data can be emphasized to help users process visual information, and how to simplify where detail is not warranted. Visual output is thereby optimized for tasks ranging from leisurely goals such as enjoyment, engagement or aesthetics to precision-oriented objectives such as visual analysis in science and medicine. My early publications were amongst the first to apply adaptive detail mechanisms in Physically-based animation and to leverage human perceptual studies of movement to optimize this adaptation. In more recent, work I conducted analogous studies applying perceptually-driven adaptation to other areas such as rendering and ultimately to solve real-world scientific problems such as real-time visualization of time-varying data, for which I received an SFI Investigator award. A key outputs of this project was one for the first models to provide automated measures for perceptual effectiveness of 3D spatial data visualization, and to use this model to automatically enhance such visualizations.
