New cell phone will count calories

It's easy to know many calories are in a particular meal when you prepare it yourself. You can easily look at nutritional labels and do some simple math. However, things sometimes get a bit more tricky when you dine out or eat an on-the-go meal.

This may all change in a few years, though, thanks to ingenuity of some computer engineers at Purdue University. As I write this, they are working to create cell phone-compatible software that will turn your phone into a veritable calorie-counting abacus.

Much like current websites that offer photo analysis of your diet, this software will review photographs you take of your food with your phone's camera. But, unlike said websites, this new device will be able to distinguish between very similar looking foods and even calculate portion sizes.
