LA Hackathon

We won a hackathon! We had great burritos after too!

We worked on a solution that allowed physical rehab patients adhere to exercises.

We used javascript library called Johnny-Five to interface with 3 imus.

We instantiated the BNO055 in javascript code. The BNO055 spits out quaternions. So no need for sensor fusion.

  var imu = new five.IMU({
    controller: "BNO055"
  });

  imu.orientation.on("change",function() {
    console.log("orientation");
    console.log("  w            : ", this.quarternion.w);
    console.log("  x            : ", this.quarternion.x);
    console.log("  y            : ", this.quarternion.y);
    console.log("  z            : ", this.quarternion.z);
  });

We were able to compare our baseline data with new exercise data and give a score on how similar two movements were.

Here’s the source code. I didn’t have type to refactor anything but it’s a simpe express app communicating over usb: https://github.com/Shakira4242/BioHacks/
