CES, the Consumer Electronics Show, is full of the wonderful and weird. And the wearable smart belt called Belty, which debuted at CES Unveiled on Sunday night, definitely falls into the latter category.

The Belty wirelessly connects with the user's smartphone so that wearer can teach it preferences based on things like sitting or standing. The Belty will automatically loosen when you sit down, and tighten when you stand up, for example.

Besides expanding when the user's waist expands, the Belty can also track activity via a built-in accelerometer.
