The wearables trend isn't just about new fitness-tracking gadgets, like the Fitbit and Apple Watch. It's a big data challenge. How can companies make sense of all the information that's flowing in from all of today’s new devices, data like step counts and heart rates, and turn that data into insights that can motivate real behavior change? Vancouver-based Mio Global doesn't believe that the solution is as simple as setting universal goals for people, like a set number of steps per day. This year, the company dedicated its resources to coming up with a new scientifically-validated metric that factors in an individuals' heart rate, age, gender, and other personal characteristics. The company claims its new metric, Personal Activity Intelligence, reflects an individual's real exertion levels and helps them set achievable goals. The company also got to work on a gadget in 2015, Slice, which includes all the tracking you might expect along with Mio Global’s PAI score.
