A Review of Subjective Assessments in Virtual Reality for Lighting Research

Sustainability, Journal Year: 2023, Volume and Issue: 15(9), P. 7491 - 7491

Immersive virtual reality allows showing people environments with high levels of presence, realism, and “feeling being”, as if they were in the real world. With this aim, must provide proper light distributions elicit sensations similar to those seen So far, experiments human subjects are most effective way evaluate accuracy reproducing spaces. This paper investigates role subjective assessments lighting research using reality. According review results, investigations aimed at immersive for can mainly be divided into three groups: (i) comparison between physical environments, (ii) analysis different scenarios, (iii) investigation users’ interaction model. On one hand, results show that is a useful tool design lighting. other highlight limitations still need overcome. Finally, main findings gaps concerning assessment listed.

A Study of the Emotional Impact of Interior Lighting Color in Rural Bed and Breakfast Space Design

Buildings, Journal Year: 2023, Volume and Issue: 13(10), P. 2537 - 2537

Published: Oct. 7, 2023

In architectural spaces, the ambiance created by lighting plays a significant role in influencing people’s emotions, often relying on use of color and light. However, previous research has primarily focused urban with relatively less attention given to rural environments, especially interior spaces accommodation. The objective this study is investigate impact colored within accommodation interiors emotions visual perceptions. Additionally, aims establish an emotional dimension model map experimental results onto eight basic utilizing PAD for quantitative analysis. To achieve goal, researchers recruited 90 participants divided them into six groups, each experiencing different combinations indoor scenes varying colors. Participants evaluated their indicate that combination cool warm white light significantly influences arousal level but lower pleasure levels, dominance relaxation levels. comparing experienced after exposure followed light, elicited more positive emotions. Furthermore, following diminished sense warmth while yellow–blue enhanced comfort blue–red increased attraction. Overall, effect improving negative was weak. Conversely, blue–yellow or green–yellow had enhancing perceptions reducing participants’ anxiety. This provides valuable insights references designing design, potential enhance spatial experience accommodations.

Cerebral, systemic physiological and behavioral responses to colored light exposure during a cognitive task: A SPA-fNIRS study

Behavioural Brain Research, Journal Year: 2024, Volume and Issue: 462, P. 114884 - 114884

Colored light has important implications for human health and well-being, as well the aesthetics function of various environments. In addition to its effects on visual function, colored significant cognitive performance, behavior systemic physiology. The aim current study was comprehensively investigate how exposure (CLE) combined with a task (2-back) affects cerebral hemodynamics, oxygenation, physiology assessed by augmented functional near-infrared spectroscopy (SPA-fNIRS). 36 healthy subjects (22 female, 14 male, age 26.3 ± 5.7 years) were measured twice two different days. They exposed sequence blue red or vice versa in randomized crossover design. During CLE, asked perform 2-back task. performance correlated changes concentration oxygenated hemoglobin prefrontal cortex (red: r = -0.37, p 0.001; blue: -0.33, 0.004) high-frequency component heart rate variability 0.35, 0.003; 0.25, 0.04). These independent CLE. Sequence-dependent observed fNIRS signals at (VC) electrodermal activity (EDA). While both colors caused relatively similar VC EDA position first exposure, greater EDA, respectively, second exposure. There no difference subjects' between CLE (p 0.46). results this provide new insights into respond Our findings are understanding impact our daily lives potential applications variety settings, including education, workplace healthcare.
