What is it about?
In this study, we describe a technology that generates a fog screen at any point in a 3D space to display aerial images. Traditional technologies, with fixed display positions on devices, made it difficult to present images at any desired location within a 3D space. This technology creates a fog screen at any point in space by colliding vortex rings launched from multiple air cannons, onto which images are then projected. This allows for the possibility of three-dimensional image displays at any location within the space.

Why is it important?
This technology offers new possibilities for the way images are displayed in everyday living spaces. It has potential applications in various fields, such as navigation, IoT, education, and entertainment. For example, There would no longer be a need to move to a location with a display when people want information; instead, information can be presented at the user's viewing location. Information about objects, animals, and plants in the space can be displayed at their respective locations, enabling users to intuitively access information related to them.
Perspectives
Aerial images hold a mystical allure and practical convenience in everyday life. In various science fiction works, aerial imagery is depicted as a highly convenient and advanced user interface. Currently, smartphones, which are highly portable and convenient, have become ubiquitous in our lives, but they also lead to problems like distracted walking. If images could be displayed at any point in the air, as with this technology, such issues might gradually improve. I hope that such technologies will shape a better relationship between humans and information in social life, influencing how we access and utilize information.
