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

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

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 ...

Subjective and physiological responses towards daylit spaces with contemporary facade patterns in virtual reality: Influence of sky type, space function, and latitude

Marilyne Andersen, Kynthia Chamilothori, Jan Wienold

Recent studies have shown that the facade and light patterns in a space are an important factor in the occupants' experience, but little is known about the generalizability of these findings in different lighting conditions, uses of space, or latitudes. Th ...

Virtual reality to assess visual attraction and perceived interest to daylit scene variations

Marilyne Andersen, Kynthia Chamilothori, Bahar Aydemir, Caroline Karmann

Façades and light pattern composition have been shown to influence the spatial experience and physiological responses of humans [1,2]. The present study examines the effect of sunlight penetration and window size on fixations to the floor of the scene, and ...

Window Size Effects on Subjective Impressions of Daylit Spaces: Indoor Studies at High Latitudes Using Virtual Reality

Marilyne Andersen, Kynthia Chamilothori, Jan Wienold

Daylight provision to the indoor space is affected by different building elements that cannot be fully controlled by the users, such as the window size of a space. The dimensions of the fenestration not only affect the lighting levels, but they also affect ...
