User evaluations of fabric shades with sun in the field of view: Glare model performance and implications for EN14501 Classification

Discomfort glare from daylight is common in workspaces, where daylight and luminance contrast between light source and background can be excessive. Fabric shadings can mitigate glare, but their light transmission properties remain difficult to characterize ...

Clear vs. overcast: Effects of sky condition on daylit view perception in virtual reality

Marilyne Andersen, Caroline Karmann, Yunjoung Cho

This study investigates how changing sky conditions in window views influence visual perception in a virtual reality environment. Over two experimental sessions, participants viewed 10 distinct window scenes, each recorded as real-time videos under clear a ...

Perception of window views in VR: Impact of display and type of motion on subjective and physiological responses

Marilyne Andersen, Caroline Karmann, Yunjoung Cho

This study investigates the effect of dynamic and static representations of window views on visual perception in a virtual reality environment. Across two experimental sessions, participants were exposed to fifteen different views-out scenes of passive nat ...

Comparative analysis of LDR vs. HDR imaging: Quantifying luminosity variability and sky dynamics through complementary image processing techniques

Marilyne Andersen, Caroline Karmann, Yunjoung Cho, Dong Hyun Kim

This study introduces a novel procedure combining image analysis techniques to examine the temporal changes in natural light, a key aspect in daylighting and built environment research. Our approach utilizes both Low Dynamic Range (LDR) and High Dynamic Ra ...

Saliency prediction in 360° architectural scenes: Performance and impact of daylight variations

Marilyne Andersen, Sabine Süsstrunk, Caroline Karmann, Kynthia Chamilothori, Seungryong Kim, Bahar Aydemir

Saliency models are image-based prediction models that estimate human visual attention. Such models, when applied to architectural spaces, could pave the way for design decisions where visual attention is taken into account. In this study, we tested the pe ...

User assessment of fabric shading devices with a low openness factor

Marilyne Andersen, Jan Wienold, Caroline Karmann

Providing adequate glare protection and a view to the outside through fabric shading devices is challenging because these two objectives require conflicting material properties for a fully lowered shading. In a semi -controlled office-like experiment invol ...

Dynamism in the context of views out: A literature review

Marilyne Andersen, Caroline Karmann, Yunjoung Cho

Previous studies have shown that access to a satisfactory view to the outside with sufficient daylight is essential for building occupants' health and well-being. It has also been suggested that certain features of visual content improve view-out quality, ...

A VR-based workflow to assess perception of daylit views-out with a focus on dynamism and immersion

Marilyne Andersen, Caroline Karmann, Yunjoung Cho

Amongst the elements often overlooked in existing studies, dynamic movement and temporal changes in the content of views-out have been suggested to have a high potential to improve its perceived quality and occupant satisfaction. Moreover, in past and ongo ...

Comparison of questionnaire items for discomfort glare studies in daylit spaces

Marilyne Andersen, Jan Wienold, Caroline Karmann, Sneha Jain, Clotilde Marie A Pierson, Geraldine Cai Ting Quek

When studying discomfort glare, researchers tend to rely on a single questionnaire item to obtain user evaluations. It is unclear whether the choice of questionnaire item affects the distribution of user responses and leads to inconsistencies between studi ...

Window View Quality: Why It Matters and What We Should Do

Marilyne Andersen, Caroline Karmann

We lack consensus on a unified definition for window view quality that is applicable across occupancies and building types. In addition, while this is a topic of growing interest, there is limited research underway due to its complex nature, insufficient f ...
