Problem

Fog screens have been used as the primary diffusers in passive aerial displays. However, they are easily affected by airflow, and their fog generators occupy large areas. These problems interfere with mobile applications such as attaching them to a drone or a person. In addition, a fog machine cannot generate fog in a short period, and there is a delay before the fog can disappear. Therefore, we cannot produce a conventional system as a wearable device, nor can these instantly project an image. How can we build a lightweight midair display with a high wind tolerance?

Solution

We employ aerosol distribution from off-the-shelf sprays as a fog screen that can resist wind and has high portability. We evaluated the feasibility of the aerosol type of fog screen. The size of the screen depends on the pressure of the aerosol spray and the nozzle used. We presented a design of the system setup and evaluated our experiments, system scalability, and applications.

Result / Applications

Our system enables a new type of application by combining it with a multicopter, wearable item, multi-viewpoint aerosol-based fog display, or embedding it in the environment. Our system allows for the exploration of new application areas for fog displays, and augment expressions of entertainments and interactivity.
