Abstract: Highlights•Illuminance and correlated color temperature (CCT) are closely related to human mood, alertness, and comfort.•Light experiments were conducted with six illuminance levels and four typical CCT levels.•The subjective feelings can be recognised through physiological features acquired by continuous signals.•In terms of the average accuracy values of the recognition framework, better results can be reached for the subjective feelings.•The research results can provide a reference of physiological features for personalised user experience research.
