Wearable technology started by tracking steps; soon it may allow your boss to track your performance

The rise of wearable devices like the Apple Watch and Fitbit offer us the ability to turn our daily lives into an never-ending catalog of interpretable data: tracking how many steps we take, the number of calories we consume, our REM sleep cycles, and even the health of our hearts.

Now a team of researchers at Dartmouth say those wearables can serve another purpose: determining whether you’re a productive employee. The data-obsessed may be quick to embrace such an assessment, but what if an employer has access that information as well?

The researchers say their mobile-sensing system, which consists of fitness bracelets, sensors and a custom app, can measure employee performance with about 80 per cent accuracy.
