THE IMPACT OF INTELLIGENT COCKPIT'S COLOR-LIGHT INTERACTION ON USER VISUAL FATIGUE
This study simulated a real intelligent cockpit riding environment using virtual reality(VR)technology to explore the potential effects of different color-light elements on user visual fatigue.To avoid the subjectivity and ambiguity of subjective judgments,a visual fatigue evaluation method combining subjective evaluation and electroencephalography(EEG)signal evaluation was proposed.In the experiment,participants experienced color-light switching during the simulated riding process.The duration of visual fatigue under different colors such as red,orange,yellow,green,cyan,blue,and purple was measured in detail.Meanwhile,brainwave data were recorded,and through the analysis of event-related potentials(ERPs)and the average power of theta waves,combined with participants'subjective feelings,the visual fatigue was assessed.The experimental results demonstrated differences in the duration of visual fatigue during color-light interaction and the potential role of color-light interaction in alleviating user visual burden.Finally,the experimental results were applied to verify the color-light interaction design of a six degree of freedom parallel intelligent cockpit.
