Florian Muller has developed Hug Over a Distance to let you tell your loved one how much you care. Here’s the scenario:
Take the toy koala and rub its belly, and it will send out a hug signal, visualized by a little animation. Your partner is wearing a normal-looking vest containing a wireless receiver, which receives the hug signal.
Small air compartments inside the vest inflate quickly all around her/his torso, giving a sensation similar to a real hug. The hug is discretely received, because others cannot “see” the hug.
