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研究和应用领域都很重要，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隐含的，著名的颜色切换#theDress就是一个例证。此外，所感知的气氛难以测量，因为它是一个整体印象，即，它将大范围的感知和情感反应结合在一个全球性的、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创造感知的气氛。在一个子项目中，我们研究了彩色光对场景中颜色视觉质量的感官影响（渲染）。在第二个子项目中，我们研究了过去经验的内隐记忆如何引起对彩色灯光的情感反应。我们测量“语义光场”，即，的ensembleof的概念语义相关的彩色照明，并测试一个定量模型来预测的情感成分的感知气氛的基础上的语义光场。在第三个子项目中，我们将我们的研究扩展到其他感知特征，如运动和声音，并使用参数化视频（“移动罗斯科”）测试“跨模态和谐”的想法。研究结果将有助于评估和理解彩色照明对整个研究和应用领域的感知氛围的影响。

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.
