Those who are trying to count calories, be it for weight loss, weight gain, or just plain old athletic training, it can be quite a time consuming task to list out everything that went into your mouth and just how many calories it contained. For the calorie obsessed this necklace can actually be a boon.

The AutoDietary smart necklace actually recognizes food based on the sound it produces when it is being eaten. This made-in-China innovation records the sound, then sends it to a smartphone which compares it to an existing database to find out what food the sound represents.

Once that is done it also counts the time you eat that food and estimates the number of calories that could have been consumed in that time slot. So far the device has had a 85% success rate of predicting the food being bitten, chewed and swallowed.  It’s been struggling on some food stuff such as soups.

Of course the science project is in a very early state and a whole lot more time and effort will go into developing the device into an actually useful tool, but the future potential of the necklace is mind blowing. It could end up being a major health aid.
