Android App Helps Quarterbacks Hone Spiral Skills
One of the more interesting applications we've seen this year comes in the form of a rather unusual video. It's the perfect spiral trainer for Android, which uses Bluetooth, an InvenSense module, an Android phone and a NERF football in order to help quarterbacks hone their spiral skills. It's obviously important in serious sporting leagues to have a beautiful spiral, and this Replay Football System allows tossers to evaluate their spiral in real time, and then check that data out in order to see just how beautiful (or ugly) their throws were.
In this demo, a Droid 2 is used, and the football is transmitting data over Bluetooth the entire time. The throw release speed, time in flight, RPM of spiral and spiral wobble (precession) are all displayed during playback, and the 3 graphs display the raw data from the Accelerometer, Gyro, and Magnetometer respectively. Have a look yourself; we doubt you'll be disappointing with the hard work that obviously went into this.
