Thanks ksloke! I find it really helpful to see how the different body parts connect, the legs especially!

Wow! This is pretty amazing! We shouldn’t be surprised, but the centre is absolutely immobile.

Thanks for sharing!

That is incredible! Master Chen is always so gracious about letting people around feel what is going on but for those of us who hav’nt had that opportunity this really helps so much….thank you!

Great!! I see how dantian works in “fajin”. There are the 3 way splits in shoulders, elbows, kua, knees etc. Turning thighs lead the energy to turn the dantian and then dantian redirect it to the hands. “Hinge” at the front axis is clear too. The principles are there in one move. So amazing.

Interesting. You can totally tell it’s him. But so much information is lost. I can’t even see his beard.

You can really see how the two kua rotate to open.

Thank you Loke for making this possible in such a short notice.

Wouldn’t it be cool if all the students have access to a tool like this? Maybe in the near future a Microsoft Xbox Kinect type body scanner that anyone can use at home that will give roughly the same data points which can be overlaid with the masters to see where we’re off. A game like program where it’ll light up on the points where you’re off and scored according to how many coordinations you got right during Yilu. Now that this data is out there in public it’s not far fetched as it might sound!

I think the kinect won’t be so accurate..

The Kinect certainly isn’t accurate enough. One day however similar devices will be accurate enough. I predict in less than 10 yrs there will be consumer level game technology just as accurate as this level of motion capture!

By the way, the invisible line in “Daniel Mroz Private on Feb. 10, 2012” Online Video become obvious. This technology can really show the energy alignment. If we can apply it to push hands, we can see how Peng energy works and what neutralization means.

Excellent! Excellent! Excellent!
Curious about 2 things:
1. The middle dantian (red dot on the chest) moves back while executing the move, is that what is supposed to be?
2. The blue dot between the lower dantian and middle dantian moves quite a distance to the left of the body, is that master chen’s tai chi belly?

I would have loved to see more data points on the torso and back to be able to see the details. But still amazing details and precision.
-For the middle dantien, i believe it is supposed to arch in. Which i believe you are right.
-And I believe that Master Chen is stretching the muscles in the belly area. I believe that due to lack of data points, it makes it look it is moving more to the left than what it really is.

On closer inspection, I think it is just that the body is rotated with the back axis fixed, therefore the front ends up rotating to the left.

Very cool

Most impressive! So much can be learned from watching this video.

Very interesting, indeed! I was thinking about connecting several iphones or android phones together with a software using their gyroscopes. I have no experience how this should be implemented, but if you position several phones onto your body you should also be able to obtain similar data. Maybe even connected to a global view with a Kinect sensor?
What do you think? Any experts in this area with an opinion on that idea?

Pawel – you can also see that Ks did mention above that the kinect would probably not be as accurate.

Pawel April 6, 2014 at 8:32 am

I meant in addition to the phones you could have a kinect supplying the grid model of the body with additional, more global data compared to the (I suppose) quite accurate phone sensors

The mocap was done on professional equipment (Vicon or OptiTrack, can’t remember which) using marker-based cameras (6 or 8 cameras position all around). Kinect does not use markers and have to guess the body posture through active projection of pattern lighting and infrared camera.
