The Perceived Atmosphere of Coloured Lighting: Sensory, Emotional, and Cross-Modal Effects

彩色照明如何影响场景的感知氛围对许多领域的研究和应用都很重要，包括认知、工作和健康心理学、视觉科学、计算机科学和工程、市场营销、设计和建筑、城市规划、艺术和电影研究。研究灯光效果的一个挑战是，关于灯光的知识往往是含蓄的，著名的颜色切换#TheDress就是例证。此外，感知的氛围很难测量，因为它是一个整体的印象，即它将大量的感性和情感反应结合在一个全局的、自发的印象中。在这个项目中，我们开发了一种新的、全面的方法来评估彩色光如何有助于营造可感知的氛围。在一个子项目中，我们研究了彩色光对场景中颜色的视觉质量的感官影响(渲染)。在第二个子项目中，我们调查了对过去经历的内隐记忆是如何提高对彩色照明的情感反应的。我们测量了“语义光场”，即语义上与彩色照明相关的概念集合，并测试了一个基于语义光场的定量模型来预测感知到的氛围的情感成分。在第三个子项目中，我们将我们的研究扩展到其他知觉特征，如运动和声音，并用参数化视频(移动的Rothkos)来检验“跨通道和谐”的想法。这些发现将有助于评估和理解彩色照明对跨研究和应用领域的大气感知的影响。

How coloured lighting affects the perceived atmosphere of a scene is important to many fields ofresearch and application, including cognitive, work and health psychology, vision science, computerscience and engineering, marketing, design and architecture, urban planning, art and film studies. Achallenge of investigating lighting effects is the fact that knowledge about lighting is often implicit, asillustrated by the famous colour-switching #theDress. Additionally, the perceived atmosphere is difficultto measure because it is a holistic impression, i.e., it combines a large range of perceptual and affectiveresponses in one global, spontaneous impression. In this project, we develop a new, comprehensiveapproach to assess how coloured light contributes to the creation of perceived atmosphere. In onesubproject, we examine the sensory effects of coloured light on the visual quality of colours in a scene(rendering). In the second subproject, we investigate how implicit memory of past experiences gives riseto the affective responses to coloured lighting. We measure the "Semantic Light Field", i.e., the ensembleof concepts semantically related to coloured lighting, and test a quantitative model to predict theaffective components of the perceived atmosphere based on the semantic light field. In the thirdsubproject, we extend our investigations to other perceptual features, such as movement and sound, andtest the idea of "Cross-Modal Harmony" with parametrized videos ("Moving Rothkos"). Findings willcontribute to the assessment and understanding of the effects of coloured lighting on perceivedatmosphere across domains of research and application.
