Will positional head tracking be activated in the dev kit?

Hi everyone. If anyone can answer this question it would be greatly appreciated. I know that prior to release I watched an interview with Nate where he stated that positional head tracking would not be ready for when the dev kits started shipping. I did however notice that with the latest release of the 0.2.1 SDK that there seems to have been some progress with correcting some of the issues (yaw drift) that was preventing them from completing development with positional head tracking. My quedtion is will positional head tracking ever be to a point where it is functional in the current dev kits? Anyone with insight into this please feel free to give your two cents. And if someone from Oculus wants to chime in that would be great!

    I'm pretty sure that would require new hardware..

    Although I'm thinking someone may correct me and say it can be done with the existing sensor...

    I'm pretty sure someone would have already done that by now if that were the case. I highly doubt you will be able to use the current dev kits for positional tracking unless you modify the hardware yourself.

    The current sensor does 3dof tracking. Right now the depth tracking (magnetometer) is not being used. So I do believe that positional tracking is possible but at this time has not been ready for operation. My question is will it ever be? Perhapse some additional orientation hardware outside of the Rift to work in conjuntion would allow this to be possible? I'm not sure though that the Rift itself would have to be modified.

    There's no reliable way to do positional tracking with the current sensor on its own. While in theory, integrating subsequent accelerometer readings (one of the sensors used in the IMU) would enable you to calculate position, in practice there are errors in each sample which would add up quickly to the point of making them unusable. Works great for orientation, though.

    l see. Thanks for the info.

    I posted an idea on positional tracking but my submission seems to have been "removed"......As most are......CHEERS MARK/MODERATOR!

    Im NOT a fully fledged developer but I do have ideas, as do we all.
    You cant really modify the hardware (these days) but we can hopefully work together and have some CON-GRAT'S for our work. What we get is what we get delivered to our door.

    NO......

    We have to work within limitations. The OCR gets lost and confused, dumbfounded even (quite a bit) Hardware VS cost.............well what route to market do you have if its too expensive?

    Basically a "moveable projector" (Albiet keyed with mouse movements on same bus)

    OCR if your reading this.........

    When the OCR comes to fruition please remember the people that forged it.

    Well...? What's your idea? I'm now intrigued by your cryptic post. Please explain what it is that seems too hot for the Oculus forums. :)

    Perhaps you hit the wrong button? I've seen quite a few ideas mentioned on this forum, so I doubt yours would have been deleted unless you were being uncivil.

    The only time I've ever seen the mods interfere was when someone asked how to battery power the rift and someone posted a circuit that would have put about 7 times the safe voltage through it. As long as your idea isn't dangerous I see no reason why your post would be deleted.

    Actually, the mods did not intervene. I convinced the original poster to remove his potentially dangerous information, and after he complied, I removed that information from the quotes in my posts too. As it turns out, the OP had good intentions, but was supplied prank schematics and a "working" prototype with HIDDEN components from a cow-orker, leading to his potentially dangerous posts of faulty "prank" information and schematics. Thankfully, we got that thread "defanged" before any Rifts were harmed...

    Here is the thread in question, which you may wish to read just for the "entertainment" value:

    In that case I have never seen a mod interfere, although I'm sure they would have. I remember looking at that circuit and going "why is he using 9volts and downvolting it? Why not use AAs? Something's not right here."

    I just couldn't figure out what.
