                 Scientists Create 'Touchable' Virtual Objects

   by George Putic

   Technology is already capable of tricking most of our senses... laser
   holography can create three-dimensional images where nothing exists,
   stereo sound can surround us, and smells can be infused into the air.
   Now, scientists are starting to break the next barrier - the sense of
   touch. As VOA's George Putic reports, scientists at a British
   university have developed a device that makes our hands feel objects
   that are not there.
