No you do not need seperate detectors for each frequency. That is what the DTMF is for. DTMF is most commonly used as telephone "touch tones" DTMF uses combinations of two tones combined to create unique codes. This can be used with IR signals as well, allowing unique identifying codes to sent and received within the same wavelength of light. Look at these microrobots. http://www.ai.mit.edu/projects/ants/ These guys can keep track of 16 different robots at a time. They do not have 16 receivers on each robot. They have four each, but that is just to give 360 degree coverage. |

As far as the actual gun mold, maybe we should talk to the guy who makes the Tron Repro Sticks (specialtyplastics). Just based on my experience in getting the translucent buttons made, plastic molding (especially custom jobs) is very expensive. Another route to go, might be to use emachineshop. What does everyone think about the importance/practicality of incorporating a solenoid? |

The cheapest solution would be some off the shelf toy gun rigged with an ir led that stayed lit all the time, and went off when you pulled the trigger, maybe flashed a pattern if you hit the reload button if you wanted to get that fancy, a $30 usb webcam, and some software like this http://charlie.dgrc.crc.ca/cgi-bin/Sylvie/Blog/casarch.pl?2004/04/13/4.txt or this http://www.edenspeace.com/eyebuddy/mousehead/getting_started.htm |

Hereis another one for camera tracking! http://www.perceptual-vision.com/Nouse/download.html This one tracks your nose, and watches for eye blinks as a click. They even have a game for it! If they can track a nose and blinking eyes, it shouldn't be too hard to track a gun with LED's on it. |

Here is another interesting project. http://www.cs.ucsb.edu/~matz/HGI/HandVu.html It's looking like a BYO RGT is possible. Oops, I duplicated the link from above. I have now corrected it. |
