Facebook is working on a technique that allows people to feel smartphone notifications through their skin when they are unable to access their device. According to a paper published by the social media giant’s research team, in-house scientists are working on a sleeve-like prototype that translates words into vibrations delivered by pads onto the arm. The wearable device could be useful in situations when a person is unable to check their smartphone, such as during a meeting or while in class. Undoubtedly that will make for some interesting changes to a school’s smartphone user policies!
