Reverse Engineering the Oculus Rift DK2's Positional Tracking Tech
An anonymous reader writes The Oculus Rift DK2 VR headset hides under its IR-transparent shell an array of IR LEDs which are picked up by the positional tracker. The data is used to understand where the user's head is in 3D space so that the game engine can update the view accordingly, a critical function for reducing sim sickness and increasing immersion. Unsurprisingly, some endeavoring folks wanted to uncover the magic behind Oculus' tech and began reverse engineering the system. Along the way, they discovered some curious info including a firmware bug which, when fixed, revealed the true view of the positional tracker.
Welcome to the internet where the facts are made up and citations don't matter...
It's not hard to monitor HID, lol. None of this is hidden, buried, or secret. It's just not published. Anyone who has the SDK can easily do what you did.
Thank Captain Hindsight. Sure, technically anybody could have done it. But no one else actually did it, despite the numerous Linux developers complaining about the total lack of positional support for them. It's pretty easy to look at someone else's work and say "Oh, yeah, that's obvious" once they've actually done it. I don't really see why you've bothered commenting since you seem to be of the opinion that the entire exercise was pointless. If you don't buy into the entire premise of the article how can you be bothered to have an opinion of whether one of the participants in the work received proper credit?
