Unified Head and Hand Oculus Positional Tracking

First off, let me say I have no idea HOW this could. I just have an idea that someone should figure it out!

Oculus is working hard on positional tracking for the head, but should they be focusing on hands at the same time? Right now there are all of these different ideas for controllers/gloves/motion tracking. What if you could use any controller or device you want and STILL have positional tracking for your hands that are ALSO relative to your head.

I got to try the Rift with the Hydra, and one frustrating part of that experience was that my virtual hands in the Tuscany demo were not exactly where my real life hands were. I'm sure there are several reasons why this is the case, but the reason I can think of is that the Rift wasn't be tracked, so where my head is located relative to where my hands are located isn't matching up. If the same positional tracking was being used for the Rift and my hands, however, I imagine it would be very easy to match up the hands being exactly where they are supposed to be in relation to my head. But how do you do this and still allow the use of any controller? My idea is positional wristbands.

You could put a wristband on each wrist, making sure that the logo lines up with the center of your wrist. These could be wireless or there could be long wires that plug in directly to the Rift. Assuming that whatever positional tracking solution for the Rift could also work on these bands, you could track the head and both hands in virtual space and in relation to each other. The bands could even track rotation and other movements of the hand. The best part is that this still leaves the hands free to use the input device of you/the games' choice.

Using this method, you could aim with an Xbox controller. You could have a game that could combine the Leap Motion and Oculus' positional tracking. You could still use the Hydra. You could use a glove. Or you could just use the bands (if it were, say, a boxing game). It's about creating an Oculus standard - all Rift compatible games can take advantage of positional tracking for head and hands, BUT it still allows the flexibility for a game to choose different input devices (you could even play mouse and keyboard and just fling your hand around for specific commands or to point at menu options).

Perhaps this idea has already been floating around. Or perhaps the next post will tell me why it's not possible. It's just an idea that, in as much daydreaming about the Rift as I do, I hadn't thought of before, so I thought I would share. Thoughts?

    With tech like Hydra 2 and Kinect One, I do not think we'll be wanting for VR tracking solutions in the next couple of years.

    I'm also very curious about what OVR will come up with.

    Sixense is touting some interesting statistics for their wireless dev kit:

    http://sixense.com/tracking-technology

    -True 1:1
    -No calibration needed
    -Wireless
    -FOUR controllers
    -12' diameter

    With it being wireless with four controllers, I imagine a lot more could be done with it.

    Interesting ! Do you know if there's a price announced ?

    No. That's the only page I've found that even gives any clue that the dev kit exists. I perused the forums looking for more details but came up empty. Google wasn't much of a help either.


    I asked Sixense (several months ago) about buying one of these for my lab and was told they have no wireless devkits remaining. It was not clear if this was temporary, a discontinued experiment, or if they were just switching to consumer-scale production.

    So I guess the question is, is this page an out of date page of the Sixense site or a new page that hasn't been fully incorporated yet? Even if it is out-of-date, it would appear that they are working on SOMETHING new - maybe they just aren't elaborating yet...

    Well, we'll see what happens. Anyway, thanks for the link !

    This post on their forums from a few weeks ago seems to indicated they're working on a new wireless product;

    I already tested wireless HDMI and it works great. Wireless USB...not so much.

    Aaaand we have an announcement:

    http://sixense.com/wireless

    Wireless controllers and THREE trackers. Two appear to be the controllers and a third is a clip on that goes on the Rift/body! Perhaps Oculus and Sixense will partner up!

    Im interested in using the MYO in this context but the frustration is of course laying hands on hardware, i cant see this being available to test with until year end. My main concern with vision based set ups is occlusion problems.

    Here is an interesting solution from MS http://research.microsoft.com/apps/video/dl.aspx?id=173838

    The problem with the MYO is that it doesn't track the arm/hand. It can't provide any 1:1 of where your arm is in space. It's simply a macro device that binds muscle movement to keys. You manipulate your fingers and wrist to flex certain muscles which trigger macros. It has no way of knowing where your arm is in virtual space, though.

    I dont Think this is the case, as i under stand it the devise also has motion sensing abilities as well im sure i read some where it can provide 6 dof data. I know the promo clip is just that, ....it shows someone controlling a slide show and sketching a circle on a slide and also FPS type game obviously pulling trigger through mussel interface, but aiming also is implied.
