Forget smartphones and calorie-calculating apps. Your clothes might be able to provide you with your meal's calorie content — no app-opening or data input required.
Researchers at the University of Pittsburgh are developing clothing embedded with tiny cameras that take pictures of your food and then calculate its calories based on the images. According to Design Taxi, the cameras even use 3D-modeling techniques to measure the size of whatever you're eating, allowing it to factor portion size into its calorie estimate.
A study of the researchers' computational method was published in the Journal of Measurement Science and Technology.
Considering the fact that American portion sizes are completely out of control and recent studies have shown that we vastly underestimate the calories in food, this kind of technology has the potential to help consumers make better choices.
