Through the looking glass, one subsystem at a time.

There are lots of exciting things going on with marker-based AR right now. I’ll get back to covering them soon, after I’ve worked out a few kinks in my own development plan 🙂

In the meantime, here’s a little look at part of what I’m working on.

  1. Wow impressive stuff. Like the interaction with the balls and allowing for multiple person viewpoints.

    Just out of curiosity, how long did this take to complete?

  2. I’m not really sure, honestly. It’s been a little over a year since I started playing with Arduinos. Everything has been in fits and starts. The hardware for a given version never takes more than a few days once I have a clear picture in my head and parts on hand. The software takes me a little longer to work out. And I totally forgot to demonstrate third-person camera control. It’s all far from complete. But there’re more parts on the way, and moving the data into other apps will make things a lot more useful on the software side.

  3. Nice work man. If you need any help designing PCBs or soldering up a batch of circuit boards, I’d be glad to help. Look forward to seeing you progress.

  4. I’m working with accelerometers right now. I’m trying to do very similar things. Will you be releasing code in the future??

  5. I’m using 2 MMA7260Q Accelerometers
    and I’ve done the calculus to find position form accelration only
    when I try to plot my two points on the screen… They drift.
    I try to add a threshold to my program but I still see drift and
    haven’t quite worked out why I’m not seeing larger movement.

    I figure I have to conduct a more evasive math study to figure out
    just what is going one.. since it’s not very impression to see 2 dots
    wander off the screen.

    How did you over come these issues??

    • Hey Chris 🙂

      I’m using an IDG300 gyro in addition to the accelerometers. My approach isn’t by the book at all, actually. There’s plenty of drift in my individual readings, but in lieu of Kalman filtering, I’m just using some ugly averaging filters to keep the noise down. The proper way to do it would be with a predictive algorithm like, again, a Kalman filter.

  6. What’s your plan with this system you’re developing? Will you integrate this into an AR system (something on a smartphone or later this fall with the Vuzix AR glasses) or is it intended stictly for VR?

    It’s a great demonstration of your project and I’m impressed you’re putting it all together yourself, but I’m curious to the intended purpose.

    And I also saw the other video from FatMan/CircutGirl and I’ll be posting that on my AR blog. 🙂

  7. Great work man!
    Seems that your gloves work really great, and they are not dependent on some kind of base station, which is also great. Hope to see your research in commercial products someday 🙂

    I’m glad that I found your blog, will visit it from time to time. Good luck!
