Amiigo is an Indigogo project that’s been in the works since early 2012. It’s a pair of accelerometers–one for your wrist, one for your shoe–that, like every other fitness device, track your movements and syncs them with a smartphone app. But what makes Amiigo different is an almost unbelievable amount of accuracy. The company claims that Amiigo won’t only distinguish walking, running, biking, or an elliptical; it can discern five different methods of bicep curls.
On paper, it all makes sense. To an accelerometer, each exercise appears as a specific pattern. Amiigo sends some engineers in to dig for this pattern inside absurd amounts of noise. A library of these reference patterns is placed on your smartphone. Then, when an Amiigo user tries an exercise for the first time, the software spots the closest reference pattern–actually swapping it out for the user’s own particular movement type. The software starts smart, then it customizes itself for optimal fidelity. You can even add your own exercises if they’re not on Amiigo’s list.
