12-inch tablet with 26-inch touch surface

12-inch tablet with 26-inch touch surface

A team of scientists from the University of Washington (UW) in Seattle
is currently working with engineers from Intel and Microsoft on a novel
gesture control system for tablet computers, which goes well beyond what
is currently possible with normal touch screen. The project, called
Portico is to expand the operating area clear, Technology Review
reported in its online edition.

"The idea is to create an interactive area that goes beyond the screen,"
explains Jacob Wobbrock, computer scientists at the UW, who was involved
in the project. This is achieved by folding two cameras that sit on
either side of the screen and moves around the screen can detect. The
system can be determined by the constant comparison of camera images and
the height of objects and determine whether they affect the surrounding
surface. With the approach can both capture hand gestures and physical
objects that can then interact with the screen says Wobbrock.

In a demonstration of the tablet will track a small ball that moves
across the table surface on which the device is located. Once the ball
touches the side of the tablet, a virtual counterpart on the screen,
which takes the same direction and speed that would have taken a real
ball. HOWEVER MAKES use a real ball for virtual games. In another
demonstration determines the angle at which a toy space ship is kept on
a table next to the tablet in the air, a virtual spaceship on the
screen, with which you can then shoot asteroids.

When the tablet is useable space, thus increasing significantly, says
Daniel Avrahami Wobbrocks colleague from Intel Labs in Seattle, who was
involved with Sharam Izadi from Microsoft Research in Cambridge, UK,
also joined the project. In a 12-inch tablet then you would have the
equivalent of a 26-inch screen.
