Im using FTIR setup I made a little progress actully past this point

One thing my fingers only glow when the lights are off witch I need the lights on :/

Im having to press really hard when moving my fingers becaue the glow will dissapers also it seems like there is a lagg with my fingers glowing witch doset make since cause I thought light was impossibly fast. blank stare

even with a good read my apps are not tracking my fingers they are just going crazy like its traking some other light sorce unless I apply alot of pressure in one spot they will stop!!

There could be lot’s of things going on there and I’m not really a FTIR guy....

Your filter could be blocking some IR, or you do not have enough leds. Also, what are you using as a projection material? If it’s Rosco then that should block most of the ambient IR from your room lights so you will be able to have them on and still use the box.

I’m not sure what you mean by the light lagging. If you mean that there is still a blob after you have removed your finger then that could be because you are pressing so hard and you are deforming the silicone or whatever you have on top of acrylic.The blob will remain until the material bends back to normal. Or maybe your computer is running too slowly…

yea Im using and led ribbion witch should be enough It was recomnded.  is it possible because Im using exposed negitive as and ir filter that it can only be visible when the lights are off?

to be more specific with the glow around my fingures I actully have to hold my hand down and the glow slowly appears like it took a while to reach my finger with out applying pressure and the when I move my fingers the glow dissapers until my fingers stop moving and the glow slowly forms back to my fingers dose that make since?

Its really hard for me to actually explain what going on though ill try out some more stuff so I have a more specific problem

That does sound weird what cam is it? How many frames per sec is it running at?

You didn’t say what projection material you are using, or whether it is on top of your acrylic…

EDIT ok, you posted that while I was typing. Rosco is for the image to be projected on to. I’m not sure you would need a separate diffuser with FTIR but like I said I’m not an FTIR guy

Im not to sure how many frames its running per second but it nothing else laggs except for the IF light.

where can I get rasco at I think that could be my hole problem it just occured to me the thing Im using as a diffuser is like velum but its a film sheet I think itsinteferaring with the IR and whats messing eveything up!!
