Head Tracking with Cliffs of Dover

[sigur_ros]

Instead of creating original open source webcam tracking software from scratch like Freetrack, a different approach could be taken -- hijack TrackIR head tracking software itself at the camera driver level. Create a driver that makes your any camera look like TrackIR camera and then all rest of work is done for you, tracking algorithm and game support all provided. Naturalpoint's worst nightmare!

Explains why Naturalpoint were so protective of camera drivers when people wanted to make drivers for Mac and Linux. But they have been reverse engineered lately making it even easier for someone to make a driver hijack. If this were the case with Freetrack I could understand complaint of 'unfair' or 'bad' since it would be completely dependent on downloaded TrackIR software. But of course this not the case with Freetrack, being independent and communicates with games directly with whatever means which is common practice for software.
