Upstanding Tiny Displays

Tablescape Plus: Upstanding Tiny Displays on Tabletop Displays by Yasuaki Kakehi, Makoto Iida, and Takeshi Naemura, The University of Tokyo :: Emerging Technologies :: SIGGRAPH2006 :: Placing physical objects on a tabletop display is common for intuitive tangible input. The overall goal of our project is to increase the possibility of the interactive physical objects. By utilizing the tabletop objects as projection screens as well as input equipment, we can change the appearance and role of each object easily. To achieve this goal, we propose a novel tablescape display system, "Tabletop Plus." Tabletop Plus can project separate images on the tabletop horizontal screen and on vertically placed objects simlutaneously. No special electronic devices are installed on these objects. Instead, we attached a paper marker underneath these objests for vision-based recogniton. Projected images change according to the angle, position and ID of each placed object. In addition, the displayed images are not occluded by users' hands since all equipment is installed inside the table.

Example application :: Tabletop Theater (pictured above) :: When you put a tiny display on a tabletop miniature park, an animated character appears and moves according to the position and direction of it. In addition, the user can change the actions of the characters by their positional relationships.
