Gadgets are connecting us in incredible ways. There's the toothbrush [1] that lets you know how your brushing is going, a bracelet [2] that measures your sun exposure, and coming soon a baby bottle [3] that tells parents how much food their child is eating, but those might all pale in the light of a smart belt. Meet Belty [4], a product from French startup Emiota unveiled at this year's CES [5] that is — surprise! — a belt. But this belt is on a mission. A mission to help you reach your fitness and weight-loss goals.

You know how after a big meal you have to loosen your belt a notch or two? Belty measures your progress in basically the same way. Onboard motors let the belt loosen itself as your waistline expands, which also acts as a message to the wearer that they should slow their roll at dinner or get back to the gym if it's a more gradual waistline progression Belty measured. A built-in accelerometer can tell when you stand or sit to loosen and tighten as needed throughout the day, so your pants are always nice and comfortable. That's . . . strangely helpful?

It also has more practical applications when it comes to monitoring your health: the belt tracks steps throughout the day that can be monitored via an app (but plenty of other gadgets [6] do that). No word on when Belty will be available or how much it will cost. So for now, this is all just wearable technology daydreams.
