Abstract
We investigated how an air conditioner’s status of operation as indicated by color affects thermal perception during continuous changes in room temperature. First, the colors that properly indicate the operation status of the air conditioner at various room temperatures were determined. Then, thermal perception was measured with and without colors for indicating the air conditioner’s operation status while the room temperature progressively changed from a high temperature to a comfortable state. Results showed that, at the beginning and the end of the experiment, subjects felt cooler when the status of the air conditioner operation was being indicated than when it was not indicated. This suggests that transition of thermal perception is modulated by color information showing the status of air conditioner operation.
