The virtual office will exist on the Internet, and you'll have a code that will allow you to
access your office portal from anywhere via wireless broadband... Everyone would have
a thin notebook PC that is little more than a screen and battery. You'll be able to beam a
holographic keyboard onto any flat surface, so you'll feel like you're typing on the wind. 

Tech Virtual Keyboard is a Bluetooth-enabled device that can be connected to
almost any computing system (laptops, PCs, PDAs, Pocket PCs or smartphones, the only
requirement being that they must be Bluetooth-enabled), and which projects, via infrared,
a holographic keyboard on any flat opaque surface. By means of a special detection
technology, the device records the keys “pressed” by the user’s fingers (more precisely,
the presence of the fingers in the area onto which a certain key has been projected) and
sends the data towards the unit it’s connected to. The holographic hologram keyboard is
also ultra-portable, because the projector is quite small (9 x 3.5 x 2.5cm ) and it also runs
on batteries (although just for a maximum of 120 minutes of continuous typing).
