A theoretical model for evaluation of non-visual effects of lighting based on human performance: Comprehensive research ideas

Non-visual effects (NVE) refer to the influence of light passing through human intrinsically photosensitive retinal ganglion cells (ipRGCs). These effects encompass various dimensions, including circadian rhythms, mood regulation, vigilance, and work efficiency. Human performance (HP) involves psychological perception, task execution, and physiological effectiveness. To systematically investigate the interplay between NVE and HP, it is essential to establish a comprehensive evaluation framework that can also delineate a scientific and clear technical pathway for subsequent research into quantitative methodologies related to NVE. We compile the current state of research on lighting’s NVE, integrating and analyzing the influencing factors associated with these effects alongside the dimensional indices used for evaluating HP while summarizing existing quantitative approaches to studying non-visual (NV) impacts. Based on these retrospective analyses and by proposing future research trajectories, we ultimately developed a HP-driven evaluation methodology system for assessing NVE. This framework provides a theoretical foundation for forthcoming studies focused on multi-dimensional evaluation methods concerning NV influences as well as guiding future quantitative investigations into this area.
