You could go to the official HP web site (sprout.hp.com), which has photos of hands, and origami, and phrases like “express yourself” that don’t tell you anything about what this thing actually is.
Or read some of the reports of people who have actually used it. The HP Sprout is a desktop touch screen computer that comes with an integrated 3D scanner and projector and the Touch Mat, which looks kind of like a big mouse pad but has a capacitive touch surface. The projector also can project images onto the surface of the 20-inch mat, which you can then interact with – like a keyboard, piano keys, or a drawing pad.
“Right now, the Sprout only scans the top half of objects — the part facing up toward the Illuminator’s cameras — but sometime next spring, HP promises support for full 3D scanning. There’s also a plan to have the Sprout send its data to 3D printers, too.”
Yes, you have to put up with Windows 8, but you can get this all-in-one package in about two weeks for $1899.99.
