- fVisiOn: Dancing Hatsune Miku on the Glasses-free Tabletop 3-D Display (June 23, 2011)
This movie demonstrates latest results of our novel glasses-free tabletop 3-D display, named fVisiOn, by introducing a virtual concert of "Hatsune Miku" known as the virtual diva in Japan.
The following is the official video. Please cite this instead of unofficial videos (June 23, 2011.)

Floating virtual 3D objects appearing on a flat tabletop surface
fVisiOn is a novel glasses-free tabletop 3D display. The developed novel technique canfloat standing 3D image on a blankflat tabletop surface, and allow multiple viewers to observe the 3Dfrom omnidirection of 360° in seated condition. It is designed to be a friendly interface for multiple users for varied tabletop tasks by featuring our glasses-free method and observation style.
For generation of the 3D images, fVisiOn employs a newly developed special optical device as a screen and a series of micro projectors arranged circularly. The combination of those devices reproduces a light field in a certain volume on the table. The light field represents a bunch of directional rays radiated from surfaces of objects which are assumed to be on the table. The light field of our method is optimized for observing in seated condition. In other words, the fVisiOn’s viewing area occupies an oblique position above the table. Additionally, our entire 3D imaging mechanism is installed underneath the table. It keeps the tabletop area clear and does not disturb collaborative work and natural communications. For example, fVisiOn can display virtual 3D images beside printed documents and physical mock-ups.
The developed system is a prototype to validate a 3D generation principle we proposed. It employs a conical-shaped optical device and over 100 projectors, and covers the viewing area of approximately 130° around the table, though it is 1/3 of ideal implementation. This primal prototype can float the 3D images of a height of approximately 5 cm on the tabletop surface like a centerpiece in the center of the table.
