In today's society, elementary school students and even kindergarten children have a smart watch. So, what is a smartwatch? In the late period of sports watch promotion due to the rapid takeoff of smart phones, the smart watch has no intention to provide the same PIM effect as PDA and smart phones, and appeals to the smart phone agent assistant accessories, similar to Bluetooth headphones are voice AIDS of smart phones, smart watch become information and data AIDS, providing more convenient and fast information display and operation. There are also other names such as Smart Accessory and Android Remote.
Smart watch from "smaller than the PDA independent computer" to "smart phone remote control AIDS", seems to have been a more successful positioning, but from CES 2014 can be seen, positioning is better after combined with smart bracelet. The smart wristband uses acceleration sensors (and gyroscopes, magnetoresistive sensors, etc.) to sense the user's running speed, step count, etc., and even can detect deep sleep and provide suggestions for exercise and sleep. When the wristband is added display, it can display time and information on the mobile phone.
