Sensory equipment enabling people to share a hug across cyberspace has been in development for several years, and experts insist it will one day become part of everyday life. Adrian Cheok, associate professor at Singapore's Nanyang Technological University developed one such system in 2005 allowing parents and children to share "cyberhugs" while miles apart. Teddy bears were fitted with sensors that detected when they were hugged by the parent, and the sensation was transmitted to the child via a special jacket fitted with heated copper wires.
