“…Most of the evaluations on the luminous environment are based on the subjective response and objective performance from samples of occupants drawn from the building users. Therefore, statistical analysis has to be applied to deal with these results, in the perspective of analysis methods, most of the studies chose to use the classical frequentist approach, such as null hypothesis significance testing (NHST) depending on the sample size and magnitude of effect, to detect the results performance [6][7][8] . Bayesian inference is proposed to be an alternative method to implement the analysis [9] .…”

Chromogenic windows enable both energy-saving and daylighting regulation. However, the human response to the luminous environment affected by them is difficult to test, since their features of dynamic change and tinting automatically. This study explores the research methods, including experimental design and statistical analysis, by literature review and an experiment demonstration. The results show that a proper size of the test room is significant to obtain desired data, and the advanced VR technologies have the potential to be applied for testing these dynamic variables. Bayesian approaches are recommended to be tried and get more accurate interference about the experimental results.

“…X-rite Color Checker Passport contains a set of three-Color Checker photography targets 34 , a desktop camera calibration application, and an Adobe Photoshop Lightroom camera calibration plug-in to create a DNG profile that reflects specific camera, lens, and lighting conditions to process the calibration of the RAW photo and restore the true color of the jadeite. Each photo was processed in Photoshop 2020, using the established environment DNG feature file for correction (Fig.…”

The application of digital imaging to color measurement is more and more extensive, which also provides new ideas for gemology. In this paper, the single-factor experiment method and orthogonal experiment design are used to study the influence parameters of the digital imaging system (DIS) on gem color measurement. Among them, the illuminance has the most significant impact on the measurement results, followed by the exposure time, and the change of the measurement distance has an insignificant impact on the results; through range analysis and analysis of variance, the most suitable measurement parameters for red jadeite are 1600 lx, 12,500 μs, 25 cm.

“…To conceptualize new research, it is important to understand the context provided by prior work, and in the case of subjective evaluations of colour rendition, there is an extensive body of literature. 2–50,62,64–81 A well-executed and reported literature review should support and justify an experiment by positioning the research question(s) within an appropriate historical context and synthesizing past results within a contemporary framework. The latter is important...…”

“…The number of articles reporting psychophysical experiments on subjective evaluations of colour rendition has significantly increased in the last decade, with more than 49 articles published since 2010, 2–50 likely accounting for more than half of the published work of this nature. This intensifying interest has at least two causes, both arising because LEDs can have different spectral features than predecessor technologies and because the composite spectrum of an LED-based system can be engineered with relative ease.…”

This article explores the best practices for conducting psychophysical experiments that investigate how colour rendition influences the perception of architectural environments. We offer guidance that covers all stages of research from preliminary development to publication, focusing especially on experiments that investigate qualities such as perceived naturalness, vividness, preference or acceptability in response to changes in the spectral power distribution of light sources. This article is intended to be a consolidated guide for researchers and reviewers of this type of research. Key recommendations include: (1) New work should be motivated by clearly expressed research questions and, when possible, explicit hypotheses that build on the existing body of knowledge, (2) visual stimuli comprising spectral power distributions and visual targets should be deliberately engineered to probe the research questions, (3) experiments should be designed to lessen potential biases, (4) reporting of experimental conditions and statistical analyses should be thorough and (5) Results should be contextual, resisting overgeneralization that cannot be supported by the data. Our motivation is to encourage high-quality research that is credible and discourage poor quality research that slows scientific progress and misuses resources.
