Controlling a Mac Via Head Movement and Sip/Puff

In this videocast I show how I am able to have complete control over a Mac via head movement and sip/puff. The equipment used is a Tracker Pro and a Sip/Puff Switch which connects to the Mac via USB.

I hope you find this videocast interesting and informative as to how I produce my content despite being paralysed from the neck down and on a life support machine.
