We propose a novel display method, EnchanTable, that can augment a table surface with mid-air images. Users can interact with visual images displayed on the table by using real objects. In our optical design, we place an optical imaging device behind a table, and the light from the optics forms a vertically standing mid-air image reflected at the table surface. This design displays the image right on the table. The merit of our method is that the only requirement is for the table to have a reflective surface. Utilizing this, we can add any devices, such as touch sensors, around the table, or display mid-air images on a tablet whose surface is sufficiently reflective. Owing to its compactness, this method can be applied to other tabletop-interaction systems.

We propose EnchanTable that augments a table surface with mid-air images. Users can interact directly with real objects as well as visual images displayed on the table. We place an optical imaging device behind a table, and the light from the optics forms a vertically standing mid-air image reflected at the table surface. It can form mid-air images in the space of 20 cm (W) x 15 cm (D) x 10 cm (H).
