Music can affect the way we feel--this shouldn’t come as a surprise to anyone, but the Mobile Music Touch (MMT) device created by a group of Georgia Tech researchers both surprises and delights. MMT takes the form of a glove with a small box attached to the top of it. It wirelessly connects to computers, MP3 players, and smartphones, which program a song into the device. Once programmed, the keys light up on a piano along with the chosen song, and a small vibration is sent to the fingers that correspond with the highlighted keys.
