“Massage Me” is a “wearable massage interface” that turns a back massage into a video game controller.
From their website:
Playing Massage me requires two people, one who wears the jacket to receive the massage and one who massages the person wearing the jacket. Soft flexible buttons are embedded in back of the jacket so that wearing it turns your back into a gamepad. All you need to do is to sit or lay down in front of a video game player and you will be able to enjoy a back massage while the game lasts.
