Wearable Tracks What You Are Eating Based On Arm Movements
The device from Nippon Telegraph estimates the amount of calories eaten by studying how the wearer moves their arms when eating different foods
Counting calories is one of the few feats that technology has failed to make simple, given that it depends on a lot of variables. Japanese tech company Nippon Telegraph and Telephone Corp (NTT) is presenting their on solution: a wristband that estimates how many calories a person is ingesting by their arm movements.
Essentially the wearable works by accelerometer and gyroscope inside a wearable, with the idea that there are different arm movements when eating different kinds of foods. While initial testing proved that the tracker could estimate calories with some relative accuracy, some foods like pastas vary in their calories due to different sauces and pasta types. The unnamed wearable was introduced at NTT R&D Forum 2017, though its representatives have made it clear that the product is not ready yet for consumer use and offered no estimate as to when it might go on the market.
