LG launched two wearable products at CES: the Lifeband Touch activity tracker (above) and the Heart Rate Earphones. Both connect to smartphones and communicate with LG's fitness app (as well as third-party apps) and are designed to work together. The Lifeband measures distance, speed, and calories burned while the earphones measure blood flow to collect data on heart rate and oxygen consumption.
Shine, by Misfit Wearables, is a wearable device that is used to track a wide range of activity. It is roughly the size of 2 or 3 stacked quarters, and uses a proprietary technique of data transfer that doesn’t require cables, charging stations, WiFi, or Bluetooth. The device displays via a series of lighted dots to indicate the completion level.
