Conference Keynotes: Broaden Your Horizons
Many conferences invite individuals as keynote speakers and many of our attendees make a point of listening to all these talks to gain a broader understanding of the current state of imaging advances.
See our preliminary 2025 keynote lineup. Additional speakers will be added soon.
Human Vision and Electronic Imaging (HVEI)
Transparency and Scission in Augmented Reality
Michael Murdoch, Rochester Institute of Technology (US)
Abstract: Optical see-through augmented reality (OST-AR) is a developing technology with exciting applications including medicine, industry, education, and entertainment. OST-AR creates a mix of virtual and real, using an optical combiner that blends images and graphics with the real-world environment. Such an overlay of visual information is simultaneously futuristic and familiar: like the sci-fi navigation and communication interfaces in movies, but also much like banal reflections in glass windows. OST-AR’s transparent displays cause background bleed-through, distorting color and contrast, yet virtual content is usually easily understandable. Perceptual scission, or the cognitive separation of layers, is an important mechanism, influenced by transparency, depth, parallax, and more, which helps us see what is real and what is virtual. In examples from Pepper’s Ghost, veiling luminance, mixed material modes, window shopping, and today’s OST-AR systems, transparency and scission provide surprising – and ordinary – results. Ongoing psychophysical research is addressing perceived characteristics of color, material, and images in OST-AR, testing and harnessing the perceptual effects of transparency and scission. Results help both understand the visual mechanisms and improve tomorrow’s AR systems.
Michael J. Murdoch is an associate professor and director of the Munsell Color Science Laboratory at Rochester Institute of Technology (RIT). He has more than 25 years of experience in color and imaging, including work on film, printing, and OLED displays with Eastman Kodak as well as research on perception of LED lighting and computer graphics with Philips Research. He leads a research project on color appearance in augmented reality funded by the US National Science Foundation (NSF) and additionally conducts research on displays and temporally dynamic LED lighting. He holds a BS in chemical engineering from Cornell, an MS in computer science from RIT, and PhD in human-technology interaction from Eindhoven University of Technology.
Experiencing Art — Changing the World to the Better
Claus-Christian Carbon, University of Bamberg (Germany)
Abstract: The capacity of art to effect transformation at the individual and societal levels is grounded in its capacity to foster empathy, awareness, and critical thinking. Art experience provides individuals with exposure to a multiplicity of perspectives, emotions, and ideas that can challenge preconceived notions and inspire novel modes of thinking. Art functions as a reflective device, reflecting societal issues while providing a forum for dialogue and introspection. Art encourages individuals to engage with the world around them on a deeper level, fostering understanding and compassion. By promoting creativity and collaboration, art can also drive positive social change, encouraging activism and inspiring communities to take action on issues such as social justice, environmental protection, and human rights. Ultimately, the experience of art can lead to a more connected, empathetic, and proactive society, making it a powerful tool for changing the world for the better.
Claus-Christian Carbon studied psychology, followed by philosophy, receiving his PhD from FU Berlin and “Habilitation” (2nd PhD) from U Vienna. He now holds a full professorship leading the department of general psychology and methodology (U Bamberg) and the EPAEG, a research group specializing in cognitive ergonomics, psychological aesthetics, and design issues. He is an editor of several scientific journals, including Art & Perception as editor-in-chief. Since 2023, Carbon is an ordinary member of the European Academy of Sciences and Arts. He is founder and executive of EBCU — the world’s biggest beer consumers’ organization, located in Brussels; founder and executive of freakstotable, one of the most influential sustainable food networks in Germany; and founder and CEO of the startup PsyAIHance GmbH, located in Berlin, addressing essential challenges of neurodiverse people.
Predicting Visible Differences in Virtual and Augmented Reality
Alexandre Chapiro, Meta (US)
Abstract: Building the perfect display is difficult, and there are many artifacts that stand in the way. We need to be able to measure and predict the quality of the image reproduction on the device, but this presents its own challenges. In this talk, I will give an overview of my process in evaluating display design decisions via subjective study and simulation. In particular, I will talk about automatic assessment using image and video difference metrics, and discuss some of the philosophy behind our work on Visible Difference Predictor (VDP) metrics. I will touch on the steps needed to make a comprehensive and accurate metric, including the need for accurate psychophysical data describing human vision. Finally, I will discuss future challenges in quality assessment, focusing on the exciting new field of Augmented Reality (AR) displays, which bring its own unique features to this space.
Alexandre Chapiro is a researcher at Meta, working in Ajit Ninan's Imaging Experiences Architecture team in Reality Labs. Previously, he worked in the Applied Perception Science team at Meta, the Core Display Incubation team at Apple, the Applied Vision Science team at Dolby Laboratories, and the Stereo and Displays group at Disney Research Zurich. He earned a PhD from the Computer Graphics laboratory at ETH Zurich, and holds MS and BS degrees in Mathematics. Chapiro is interested in solving novel problems for industry applications by modeling human vision. His work touches on perception, computer graphics, computational display, and psychophysics. Prior work involved perceptual difference metrics, brightness and color, stereo 3D, and display topics like virtual and augmented reality, frame rate, high dynamic range and more.
