6 dof tracking

6 dof tracking
6DOF or 6 degrees of freedom refers to 3 axis accelerometer (linear) and 3 axis gyroscope (rotation) which ideally is all you need in an IMU (Inertial monitoring system. Well thats the theory, in truth only a few seconds later the numbers have gone to crap...but with some tricks thats no problem.
Sparkfun are a neat company that sprung up in the US catering to the hobbyist that wanted to use specialist electronics but might not have the resources. Started as a couple of boys out of collegue they have rapidly gained a repuptation for quality low cost solutions and fun projects. They have a range of modules including a range of inertial monitoring units. We have used these units for some of our sword monitoring and soccer throwing projects(link for this work yet to come)
