'Belty', a smart belt from French-based startup Emiota, unveiled at the Consumer Electronics Show (CES) aims to help people lose weight. The gadget is embedded with sensors and starts vibrating when it determines you have eaten too much, and also sends a signal when you are sedentary for too long.
Emiota's Carine Coulm said, "If you are sitting at your desk too long, it will vibrate and tell you to get up and take a walk."
The belt loosens when its wearer sits and tightens on standing, simply sensing body movements. It can be connected to a smartphone app which acts as a fitness coach.
The device has notched one of the CES Innovation awards at this year's giant Las Vegas tech show.
