That’s what MIT researchers Melissa Chow and her colleagues Andy Payne and Phil Seaton at MIT have come up with — a jacket that hugs the wearer when one of their friends ‘likes’ one of their posts on Facebook. The Like-A-Hug vest is described as receiving a signal when a Facebook friend "likes" a post, then fills with air to give the wearer the sensation of being hugged.
I’m not sure they’ve really thought this one through.For one thing, have they thought of the reaction of passersby when the jacket suddenly starts inflating when you are standing in line at an ATM or waiting for a bus? And what about when you are packed tightly together on a metro train in the rush hour and the hug is shared by four or more other people?
It does widen the whole concept of the user interface though, doesn’t it?"
