Power shortage has become a perennial problem in Japan after the Great East Japan Earthquake. Energy saving measures adopted to deal with this situation have prompted worker complaints about the cold and consequent lack of concentration. In this study, we propose a way to change the perceivable temperature using a psychological approach rather than adjusting the physical temperature alone. Experimental evaluations confirm the effect of color and sound stimulation on thermal sensation. Participants indicated an increase in the perception of warmth when provided with a stimulus reminiscent of stove operation.
