Color Appearance in Optical See-Through Augmented Reality
Optical see-through AR presents virtual objects to a user through a transparent display that blends them with the real-world environment. This developing technology promises new opportunities for telepresence, training, user interfaces, and more. However, the optical blending of AR with the background means the AR content can be distorted in color, brightness, and contrast.
This presentation will explain optical see-through AR, show experimental evidence of visual discounting of AR and real-world components, and demonstrate the perceptual similarities between transparency and induction. A model of visual discounting will be reviewed and tested, and a framework for updating color appearance models will be proposed.
LED Lighting: The Intersection of Color Science and Design - Tuesday 2:15 - 5:30
Currently, LED technology leads the market for electric lighting, primarily promoted for its substantial energy efficiency. Beyond energy, however, the flexibility offered by solid-state lighting (SSL) – including LED and OLED – allows lighting to provide a breadth of benefits to the human experience: color, vision, health, art, performance, and happiness.
This course will be provided jointly by a color scientist and a lighting designer, each bringing their own perspective to the multi-disciplinary field of lighting. The instructors will explore an apparent collision course between discoveries made in lighting research, progress made in LED technologies, and preferences in approaches to lighting applications. Focusing on color in architectural lighting environments, they will cover topics including:
- LED light generation, white and colored LEDs
- Color rendition, the effect of light source on object color
- Light distribution and the design of appearance
-Healthy lighting, including more than what we see
- Energy and money, impact on design and controls
- System implementations, LED possibilities and architectures
Understanding some of each of these topics will illuminate how lighting designers, scientists, and engineers collaborate to impact the LED lighting products available, the codes that are written, and the outcomes of architectural designs and implementations. Mike and Kim will provide suggestions for the application of lighting color science knowledge to further the areas of art, design, product manufacturing, and human wellness.
The course will be given in the Munsell Color Science Laboratory, allowing participants to see and use advanced LED lighting systems and color measurement instruments.
Bio
Michael J. Murdoch is an Associate Professor and Director of the Munsell Color Science Laboratory at the Rochester Institute of Technology, where he teaches topics including colorimetry, psychophysics, lighting, and imaging. He leads an NSF-funded research project on color appearance in augmented reality (AR) and also conducts research on displays and temporally dynamic LED lighting. He spent Fall 2023 as a Fulbright U.S. Scholar in Ghent, Belgium, collaborating on research with K.U. Leuven. Before coming to RIT, Mike worked for Kodak Research and Philips Research, developing color system models and human-centered designs for solid state lighting, LCD, and OLED display systems. He holds a BS in Chemical Engineering from Cornell, MS in Computer Science from RIT, and PhD in Human-Technology Interaction from Eindhoven University of Technology in The Netherlands.

The Inter-Society Color Council advances the knowledge of color as it relates to art, science, industry and design.
Each of these fields enriches the others, furthering the general objective of color education.
