Abstract
Communication window lighting (CWL) had been proposed as a system to provide information from the external world into a closed space. In this system, the brightness and color of the external world are reproduced on windows to provide information such as time, direction, and weather. In our experiment, subjects estimated the perceived time, direction, and weather using the CWL. We examined the effectiveness of brightness and color information. We found that brightness reproduction mainly contribute to providing time information and color reproduction effectively provide the weather information.
