Scientists at the University of Sussex have invented a new algorithm that enables smartwatches to detect and record your every move, without being told beforehand what to look for.
Current smartwatches can recognise a limited number of particular activities, including yoga and running, but these are programmed in advance.
This new method enables the technology to discover activities as they happen, not just simply when exercising, but also when brushing your teeth or cutting vegetables. The algorithm can even track sedentary activity, for instance
whether you are lying or sitting down.
Dr Hristijan Gjoreski of the University of Sussex said: “Current activity-recognition systems usually fail because they are limited to recognising a predefined set of activities, whereas of course human activities are not limited and change with time.
“Here we present a new machine-learning approach that detects new human activities as they happen in real time, and which outperforms competing approaches.”
