eButton tracks your diet and level of activity

Are you trying to lose weight, but don't like keeping track of your food intake? Well, there may or may not be an app for that, but there is a button. An eButton, to be precise. That's the name of a wearable device developed at the University of Pittsburgh, that incorporates a camera, accelerometer, GPS, and other sensors. These all work together to maintain a profile of not only what the user is eating, but also how much exercise they're getting, how much time they spend sitting around, and other factors that can affect weight gain.
