Tabletop displays have been used to share information among multiple users. However, there are two problems with current tabletop displays: The display area is limited to horizontal surfaces, and there is a lack of view-dependent appearance regarding displayed images. The aim of this paper is to overcome these limitations by adding dual-sided vertical mid-air images to a horizontal surface for a richer and more impressive visual presentation. For this purpose, we introduce a plate-shaped mid-air imaging optics as a tabletop surface and a diffusion control film for the projection of horizontal images. The proposed system, "HoVerTable," can display a combination of horizontal and vertical images for users facing each other. We have developed interactive applications on HoVerTable, including a card battle game and an application for the augmentation of physical objects.
