The user can casually open up the desktop.  Cameras can detect users’ fingers to switch back and forth between the 2d and 3d  interfaces to suit preferences.  A user can grab 3D objects in a grid through a unique Samsung transparent display technoloy.  They are hoping to provide a more natural interaction with desktop computing.  This is pretty awesome.  If nothing else it may reduce carpal tunnel syndrome which would be incredible.  No more searching for files til your fingers are tired by constant mouse clicking.  And maybe as it improves typing speeds will increase, as well as creating presentations much quicker.  The possibilities are endless!
