MEMS-based Tunable Metasurface for Reflective Display Applications
In an era where portable electronic devices are indispensable for a wide range of activities, the need for displays that provide both long-lasting battery life and excellent visibility in different lighting conditions is increasingly important. Emissive di ...
EPFL2024Implementation of a tracking system in the eM+ lab panorama
Alexandra Lagutova, Paul Marie Michel Madelénat
This bachelor project, conducted at the Experimental Museology Laboratory (eM+) at EPFL, focusing on immersive technologies and visualization systems. The project aimed to enhance the Panorama+, a 360-degree stereoscopic interactive visualization system, b ...
2024Perceived glare from the sun behind tinted glazing: Comparing blue vs. color-neutral tints
Marilyne Andersen, Andreas Schueler, Jan Wienold, Sneha Jain, Maxime Lagier
While the influence of a glare source's spectrum on sensitivity to discomfort glare has been demonstrated repeatedly under electric light conditions, it has not yet been studied under actual daylit conditions. To investigate the influence of spectral alter ...
2023INVESTIGATING MULTIPLE GLARE SOURCES IN DAYLIT CONDITIONS
Marilyne Andersen, Jan Wienold, Geraldine Cai Ting Quek, Chui Ling Yuen
This study explores the effect of multiple bright light sources in the field of view on discomfort due to glare in office environments. User experiments were conducted in semi-controlled dim daylit environments mimicking open-plan offices, with glare stimu ...
International Commission on Illumination2023Variation in Phototopic and Melanopic Lighting in Swiss Offices: A Field Study
Marilyne Andersen, Jan Wienold, Caroline Karmann, Megan Nicole Danell, Clotilde Marie A Pierson
Health requirements for lighting in buildings are becoming increasingly important in building standards. Yet, there is a lack of concrete data on the lighting conditions that prevail in our workplaces, in terms of their spectral characteristics, their seas ...
2023Visual comfort without borders: Extending daylight glare prediction to dim daylit environments
Avoiding discomfort glare is one of the critical aspects of maintaining visual comfort, which significantly influences occupants' overall satisfaction with their indoor environment. Discomfort glare prediction models have been developed for various lightin ...
EPFL2022Effects of illuminance intensity on the green channel of remote photoplethysmography (rPPG) signals
Point-of-care remote photoplethysmography (rPPG) devices that utilize low-cost RGB cameras have drawn considerable attention due to their convenience in contactless and non-invasive vital signs monitoring. In rPPG, sufficient lighting conditions are essent ...
SPRINGER2022Validation of spectral simulation tools in the context of ipRGC-influenced light responses of building occupants
Marilyne Andersen, Clotilde Marie A Pierson
With the growing awareness about ipRGC-influenced light (IIL) responses, design applications related to these responses are flourishing. To compare design options and optimize lighting conditions for building occupants, lighting simulations are typically u ...
TAYLOR & FRANCIS LTD2022The framework for improving air quality monitoring over Indian cities
Athanasios Nenes, Satoshi Takahama, Arindam Roy
Indian air quality monitoring guideline is directly adopted from World Health Organization (1977) guidelines without place-based modification. According to Indian air quality guidelines (2003), the location of monitoring sites should be determined from air ...
2022Direct time-of-flight SPAD image sensors for light detection and ranging
Depth sensing is an increasingly important feature in many applications of consumer, automotive, augmented/virtual reality (AR-VR), space and bio-medical imaging. Long range, high depth resolution, high spatial resolution, and high frame rates are often co ...
