answer in this thread if you have an idea.

You should probably obscure the filename a bit. Oh, and I found the original(?) pic. Mum's the word.

[Zeealex]

alllrighty then i already obscured the original filename, i obviously wanted you all to know that it is being detected through NVGs or infa red


what does mums the word mean?

Shakespeare started the 'Mum's the word' expression. It's an idiom. Means 'say nothing about it' or 'be quiet', although it doesn't seem to fit in this context too well....

[Zeealex]

well, thinking about it, now that i know what it means, it actually does fit quite well

thanks for telling me BTW

Its how a kinect sees the world. Basically ray-tracing.

[Zeealex]

well done Petsfed!

[RileyFletcher_01]

He must've cheated. Nobody but me could've gotten it right.

[Zeealex]

are you sure about that?

[bobmanuk]

i was going to suggest you are made up entirely of fiber optics and run off light.

The photo proves this!

Either that or you are part of the matrix

Radioactive isotopes?

I saw similar pictures on slashdot when the Kinect was first hitting the market. Basically, the kinect throws out infrared beams to measure location and velocity of everything in the room, giving a sort of sheet-ghost image of what's going on. Then it fits a human skeleton to the thing that's moving the most, and that's how it determines what you're doing. Since human clothing doesn't tend to be terribly interesting in the specific infrared frequency range, it works the same as motion capture tech, but without the tracking marks glued on.

I'll bet you could glitch it by wearing a ghilly suit, removing the grate around an oscillating fan, or by playing with an unrelated remote control at the same time.

Putting your finger in an electric socket would also help.

And I still don't understand what's even going on. What's this picture all about?

A laser range-finder works by bouncing a beam of light off an object, and measuring the transit time of the light. Radar works either by sending out many such beams (this time in the radio frequencies) and measuring the change in transit time, or by measuring the frequency shift of the object (this is hard to do for very slow objects).

The kinect does the same thing, but with infrared beams. What you're seeing is the dozens (hundreds?) of beams hitting somebody's hand, as viewed through e.g. night vision goggles. The xBox then fits what it sees with a human skeleton, and therefore translates your gestures into commands.

I believe (although I haven't verified this yet) that the reason for the change in xBox hardware in part involved optimizing the hardware for both image analysis and very fast curve-fitting. Even then, the delay between your gesture and the video game response is still noticeable, although slight.

but it emits thousands maybe even Millions, i can see why it is suggested for you to stand 4m away now.

it's cleaver stuff for what it is.
