A virtual Keyboard:

Everyone knows what a keyboard is.Right and Maybe the different types in it:Be it wireless,wired,usb et al.

Ever heard of a virtual keyboard.One which you can use.But the keys rarely exist physically.

You should be confused by now.Making it clear this is what a virtual keyboard is:there are NO KEYS.

You have a laser projector sort of a thing that projects a beam.

The beam creates a pattern similar to a keyboard with keys.All you have to do next is to start typing just like you would do in any other keyboard.As simple as that.

No wear and tear of keyboard,and further you dont need a place for the keyboard.All you have is the projector to project the beam.

And further it can be used for mobiles even.

truly amazing stuff!!!!
