"Mirror, mirror on the wall, can I lose weight this fall?" This is not the "magic mirror" from Snow White, but a smart mirror developed by Japanese electronics giant Panasonic. The eye-catching mirror was displayed at the 2nd China International Import Expo (CIIE). It can display body data, such as your weight and body fat percentage and suggest ways to stay fit. Panasonic also displayed a smart toilet, which has an advanced sensing system that allows it to measure the user's muscle mass, heart rate and even sleep quality.
