Wiimote Finger Tracking / Re: Minority Report
« on: May 18, 2008, 08:28:38 AM »
i plan to make a glove also.. only.. isent it stupid to put leds on the glove.. which means u now need some battery power which who knows where u can put so its out of them, and then u need to replace it every so often.. prity stupid..

this is why i think johnney lee figured out the whole useing reflective tape deal..

just stick reflective tape on ur fingures or glove and wala done..

of course u need the led array

IR Pens / Re: IR light from a distance
« on: May 17, 2008, 01:06:31 PM »
"well the IRleds arent super strong"
i wounder about that..

i have these 5mm IR leds from radioshack
Radiant power output (100ma) 16mW min
Foward voltage 1.2v
Foward current 100mA
Viewing angle to 1/2 intensity 45 degrees
Wavelength 940nm

thats all the info it says on the package i dont fully know what all means but incase was woundering what i was testing with.

anyway.. stuck 1 in my keychain flashlight and worked perfectly fine accress the room. i desided to try even farther max distance i was able to check is about 25-30 feet.. i had feeling it would work from at lest 5-10 more feet..

the only problem is i supose with the program.. the farther away u get from the camera the more you have to move the light around to go from top to bottom of the screen..

dunno if the camera can measure distance..?  if not just need to add something that can measure how far you are from the camera and make it all relative.

IR Pens / maglite ir :) easy
« on: May 16, 2008, 09:13:30 PM »
here is what i did for my whiteboard pen
bought this http://www.maglite.com/product.asp?psc=1AAACELL&pt=R
8-9$ idk
unscrewed the top area where the light bulb is and replaced with an IR led.. just cant stick the lense thing back over the light but i dont mind..

Project Ideas / different ir lights?
« on: May 13, 2008, 08:50:12 PM »
just my thought on something..

if light is wavelengths then ir light is also a wavelength? doh
if the frequencey of the ir light can be adjusted like a radio tuneing to a different channel..
then you have solved the xyz 3d 3 cameras what ever ur idea was to figure out which point is which if you are useing multiple points.. as long as u emit the light and not reflect it.

same deal for the multiple head tracking..
as long as u had split screens or multiple screens.. 1 for each head tracker it should be no problem..

im sure its not so easy to change the wavelength or ir light.. if you changed it would you still have a camra that can see it? so what im saying is if the light wave is changed then the camra also needs to be adjusted.. kinda like tuning to a station..

idk maybe this is stupid.. i guess the average person can not do this.. but i have a feeling its the future of ir or it already is and im stupid.. haha
