Mid-air imaging technology enables computer graphics (CG) images to move around in the
real world. However, the big form-factor of large-format mid-air displays makes them bulky
and limits their applicability. To reduce the size of such displays, we propose an optical
design that realizes mid-air image movement by rotating the reflecting surface and the light
source with motors and thus moving the virtual image of the light source. We made a
prototype based on the calculation of the mirror and display angles and the distance …
