Facebook vest hugs user every time they receive a 'like' on social networking site The vest's creators say the invention allows us to "feel the warmth, encouragement, support, or love that we feel when we receive hugs." MIT student Melissa Kit Chow, who designed the jacket, said: "The project was done as an exercise and exploration in shape display. We came up with the concept over a casual conversation about long-distance relationships and the limitations of video chat interfaces like Skype. The result was Like-A-Hug. Connecting it to Facebook conceptually was simply a way to explore how social media might push past the traditional graphic user interface (GUI). Since Facebook began, more than 1.13 trillion items have been 'liked' on the site, the firm recently revealed.
