xLabs is a lightweight head pose and gaze tracking application through your webcam.
I have built a controller using xLabs that allows you to control your ship via head-movement.
In order to play with head-movement, you need to install xLabs first.
Install the xLabs chrome extension, restart your browser. At the launching page, use the default xLabs controller and start the game. Then you can control your ship by slightly tilting your head.
