sadly, i didnt understand everything you said, since english is not my native language aswell but i will try to cover some things you mentioned:
1) i can try to fix the "javaw.exe" termination error.
2) as far as i understand, you would like a video stream to test your color tracking settings with, instead of an image. i can see the advantage of this, but this is far more complicated to implement, aswell as it takes much more computing power. i will see if i can do anything about it, but i can't promise.
3) i can also try to add a section that shows you the current sound level, though i dont think this would be really necessary, as you can just start the sound level detection with the lowest threshold (and don't make a sound yourself), and see if any noise around you gets detected. if so, continue this process with a higher threshold until no external noise is being detected anymore. when i get time, i can implement a section like this though.
4) sorry, i dont think i will be able to make the color detection process any easier, since the program has to work with HSV values. i am pretty sure i will not be able to implement a HSV circle instead of the sliders.
5)
sorry, i dont really understand this paragraph. it is a matter of fact, that you have to be close to the webcam so that it can track your object. or are you using an USB webcam which is close to your object, but the screen of your computer is far away, so that the "Movement Control Panel" is too small for you to see? please reply to me about this. meanwhile, i would suggest to use a beamer- Would not it be nice to have the option Installation menu size and distance boxes in the "Movement Control Panel" If I use a colored object ballgag, I must be close to the camera (almost inclined above the keyboard ). When distant scenes must do the movements over long distances. This can be a problem, for example, in programs other than Selfbondage Memory Game. It will probably be difficult to implement and will need to think ahead more correct solution.
