Arriving just after breakfast, our first stop was at the Hunger Analyzer station, where DoCoMo reps were on hand with a Bluetooth accessory that measures acetone levels, sending results to an app that determines not only if it's time for you to eat, but also whether or not your body is in a good position to burn fat with exercise.
While the strap on the back is an optional accessory, we see its appeal for securing the device in hand, and fully expect it'll be a popular add-on for enterprise customers.
