Airflow interaction with floating images

This new optical device forms virtual images that appear to float in the air. In combination with a contactless airflow detector, it provides a new method of interaction. The floating image reacts when users blow air into it. For example, an image of a flame flutters or dies, or dandelion seeds are dispersed in the "wind." In another modality, users "touch" the image, and the finger position is sensed by an infrared screen.
