It is known that the South Korean manufacturer Samsung is working on a new fitness tracker under model number SM-R150. There are no exact characteristics about the gadget, but it is expected that there will be a round display with a rotating bezel, like the Gear S2 smart watch, the Tizen operating system and the ability to connect to mobile devices, such as a smart watch or smartphone, to transfer data to the proprietary application. The novelty will be able to recognize different types of activity and physical activity, will be able to take steps taken and calories burned, measure heart rate, heart rate, percentage of fat and water level in the body. It is difficult to say how much the attributed functions will correspond to reality, it is possible that something will remain only at the desired level for now. A promo video published on youtube shows Samsung’s new Body Compass 2.0 tracker. A prototype of this device was presented at the last CES 2016 exhibition. The sensor is a kind of unifying analytical center that processes data from wearable smart sportswear during exercises. Thus, the module monitors activity throughout the workout, figuring out whether the user performs lunges, push-ups, pull-ups, squats and other exercises correctly, how many approaches have been done, and controls vital indicators. However, without the availability of appropriate clothing, it is extremely difficult to obtain accurate indicators.
