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:
Calculate the orientation of each hand in space.
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.
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).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
