This software was developed by the joint research project of Keio University SFC Wakita Laboratory and Daikin Design. The aim of this project is to visualize indoor airflow from art and science perspective. The intention is for users to reinterpret the recognition of air conditioner. Air conditioner is an equipment used to sustain comfortable living spaces by adjusting the air. Nevertheless it is not easy to control the airflow invisible to human eyes. We could control the direction of air vent and the air strength by remote controls, but wouldn't be able to understand the air flow itself in details. In this project, we challenged to visualize the beauty of indoor air flow.
