Leap Motion IR cams and filters

Hi there,

Does anyone knows if the cameras are IR or are standar cameras with an IR filter?

I would like to change the leds and camera light wavelength sensibility to allow two leap motions work one beside another without having interferences between them.

Any idea? Any project related?

Thanks

That would be very difficult to accomplish in a way that wouldn't completely undermine how the tracking works. Fortunately two different controllers don't mutually interfere with each other enough for it to be an issue.

You are right, it's surprising the great work of the device when there are more than one present.

Problems appear when you have two subjects A and B a bit close, in that case if Device A lost the hand of its subject it will take the hand of subject B if its into his detection box.

I think about the device as a camera, if I reach it to se the hands, whatever the wavelength and filters I use, it will track it right.

Maybe someone has some technical information about the cameras ¿?

Multihand setting allows each camera to track many hands... making programming constraints easier...

Not sure why you want more than one camera..but If you have VR headsets on different people... and your hands will be getting close... or going off screen..
...Remember the focal area of the camera is like a big basketball and you can tighten up the tracking range.

If all else fails
1)You could apply a identity marker in the AR like a bracelet, ring, handstamp, etc. to keep everything straight
2) You could ask why you want people that close together, when they could do the same thing from different rooms and be in the same virtual space...

good luck

Thanks a lot for your comments Hothands!!!! My goal is to allow two persons sitting one beside other like in a spaceship cabin simulator, the experiece is focused in makings things and taking decissions working together, in the same physical space.

Can you write down some links about the multihand threatment? And any other reference to the use of bracelet and other stuff will be welcome

Thanks a lot
