Not sure if anyone has posted a link to this YouTube vid yet, but this kid is showing off positional head tracking using a Razer Hydra controller strapped to his head whilst using the Oculus Rift. http://youtu.be/GQK48duvld0
Ha, I knew somebody would do it before I got a chance.
My plan is actually to use a couple of AR tags stuck to the rift along with the webcam built into my computer to see how well I can get positional data using computer vision.
Wow! I ordered the Hydra when they were offering their 50% VR discount, but they wrote me that it take a while to arrive since they were out of stock. But this is exactly what I was planning to do. Is it accurate enough to completely replace the build in headtracker?
Maybe Oculus could use a similar system in their consumer version of the Rift 😉
