Nowa smartwatch that tracks your every move

Scientists have created a new algorithm that enables smartwatches to not only record your exercise session but also detect when you are brushing your teeth or cooking, an advance that will provide a richer and more accurate picture of your daily life. Current smartwatches can recognise a number of particular activities, including yoga and running, but these are programmed in advance. The new method, developed by researchers from the University of Sussex in the UK, enables the technology to discover activities as they happen, not just simply when exercising, but also when brushing or cutting vegetables. Traditional models “cluster” together bursts of activity to estimate what a person has been doing, and for how long, the researchers said.
