Keywords:Omnidirectional Aerial Display, AIRR

An omnidirectional display that projects images to the front, rear, left and right has an advantage of
showing an immersive feeling because of a wide viewing angle.
By Aerial Imaging by Retro Reflection (AIRR) by retroreflection,
We proposed a method to form an all-around type aerial image using a conical beam splitter (BS)
We conducted a behavior observation experiment of medaka using this full circumference type display,
and showed the reaction when displaying the whole circumference aerial image on the outside of the cylindrical water tank.
However, it has not been reported what medaka will react when displaying an aerial image in the water.
Therefore, we propose a method of forming an aerial image inside a cylindrical water tank by changing
the BS position of the all-around aerial display.
