We have constructed a table-type device that projects 3D images in mid-air by applying aerial imaging technology (AIRR) based on retroreflection. The system outputs depth-inverted images on a 3D display that creates parallax using the lenticular method, and uses AIRR to form mirror images of these on the table surface, enabling observation of 3D images from various angles.
However, this method tends to cause discrepancies in the depth relationship between objects on the desk and the images, particularly creating a strong sense of incongruity when trying to directly touch the images. To address this issue, we developed an interaction technique using shadows. By casting hand shadows on the 3D images when hands are held over the desk, the depth perception of the images becomes easier to grasp, and the sense of reality is enhanced.
