Scientists Create 'Touchable' Virtual Objects

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.
