I haven't yet tried a modern VR system, but that's some crazy low latency. I know Mr Carmack is all about low latency :)

  here is another low latency solution that also tracks rotation of the object: https://www.youtube.com/watch?v=p7IL0Gvux7U https://www.youtube.com/watch?v=p7IL0Gvux7U the Ishikawa Watanabe Laboratory have some crazy low latency setups 3D object rotation tracking demo: https://www.youtube.com/watch?v=rrvAHh3-4qU https://www.youtube.com/watch?v=rrvAHh3-4qU

    that second demo has considerable lag

Leap Motion's new SDK has also been getting positive reviews. http://blog.leapmotion.com/orion/ http://blog.leapmotion.com/orion/ It has taken several years but it looks like this technology might finally be ready for general commercial use. Hopefully, we can use it for more than gaming.

  That looks seriously amazing and its backwards compatible with original hardware. I wish I hadn't thrown out Leap Motion in garbage .

From the article I could not figure out how it determines the full XYZ position of the retro-reflective object. Clearly it is possible to determine the ray along which the retro-reflective object will be, but how does it determine its depth? I do not see the article mention anything about time-of-flight measurements for the laser or that you need a stereo setup that will triangulate the position. The article shortly mentions needing two retro-reflective objects to determine the XYZ. But do you then need two lasers, or does one laser quickly alternative between the two objects? Edit: just re-read the article. The idea is indeed to use two base stations or a second marker. That makes me wonder about the scalability of this solution. What about the typical HMD + 2 6DOF controller setup? 6 Base stations?

  I was wondering the same things. He said that adding a second marker would be easy, so I suppose the idea must be to alternate between the objects. Three markers and one base station ought to be enough to get 6DOF tracking, but of course a practical system will need many more to handle the user facing the other way, and that may not be practical.
