Interior design of train cabins play an important role in providing comfortable transportation, since visual stimuli have major psychological impact on passengers. To evaluate the amenity of cabin’s interior design, we focused on data of brain activity which lead to intuitive favorability obtained by NIRS in addition to a subjective evaluation by questionnaire. We made an intuitive sight evaluation of interior design for Shinkansen by observing brain activity in reaction to a variety of image showing different combinations of cabin facilities’ colors and lighting color temperature to propose appropriate conditions for a comfortable cabin environment. As a result, on the whole, lighting color temperatures of 5000K were more highly regarded except in the case of blue facilities. However, blue facilities were favored at illumination temperatures of 3500K. On the other hand, the case of red facilities was more highly regarded in the highest lighting color temperature of 6500K. Moreover, to verify the impact of visual stimuli while train is in motion, subjects wearing virtual reality headsets were seated in a train-riding simulator, and stress brain indices and mood brain indices were measured in addition to a subjective evaluation. In the case of blue (3500K), the subjects consistently felt stress-free. We found that a combination of cool-color of facilities and warm-color light temperature is most preferable, which shows good agreement with the results obtained from subjective evaluation by questionnaire. Consequently, NIRS is useful to evaluate the amenity of cabin’s interior design. |
