Building a Multitouch GUI

The FireFly MV has a high IR-Sensitivity, and a lot of Parameters are adjustable through Software and SDK.
This post made me aware that it is vitaly necessary to adjust some parameters like “exposure” and “Brightness” or the camera will be in an Auto-Modus that will take control of the parameters and basically do what it thinks is the best. But we dont want that.

With parameter “exposure” Auto-Mode on , you get a Value of 58. The resulting picture is very bright, altough it can see IR, everything else is very bright too. We have no contrast here.

Whitout the auto-mode you can set the parameters freely.
Now I like the results:

I will have to experiment with the best settings, now I just use a Wii-IR-Led-Bar and a 4×7-Led-IR flood to check sensitivity.
Next Week I expect to start experimenting with different high-power IR-Leds to try and finally get the FTIR-Blob-Effect working. I ordered half a dozen different IR-Leds, with different angle of radiation, so this will be fun to learn what works best.
