Vince Lombardi had a great quote “Inches make a champion”. The producers of Hykso, a tracking sensor for boxers would agree with that winning comes down to the tiniest of margins.. They have produced a nicely packaged set of accelerometers that use BLE communication to transmit punch data to a sexy iOS app.

Boxing Specific Algorithms

Our motion tracking algorithm uses 3 sub-algorithms developed specifically with the punching motion in mind.

Their cumulative goal is to:

1. Calculate the orientation of each hand in space.
2. Translate the motion to a fixed reference frame (a.k.a. the frame everyone is used to, the earth’s frame) from the complex frame of a fist in motion.
3. Remove the pesky gravitational readings from the accelerometer (this is actually one of the harder things to do, and we’ve developed a better way to remove it compared to traditional methods).
