During an event of CES 2014, Sony unveiled a small device that can be the core of many wearable devices to come - not only those who are released by the company. The device, called Core, will rely on battery that lasts for five days and is even able to send notifications via vibrations (Read more about Sony Core). For now, the main product that uses the Core is SmartBand SWR10. It is a smart wristband that works as a physical activities assistant.As you might guess, the operation is very simple: you put the device in your wrist and it begins to collect related data about your physical efforts.
However, due to the Core, the SmartBand does more than compute calories burned in races, for example. The bracelet from Sony can record data throughout your daily routine, showing if you sleep well, identifying movements made and even media used within the last 24 hours.
