Applications / Re: Tracking Fingers - makin it REAL ?
« on: October 19, 2008, 04:55:08 PM »
I am extremely interested in this as well

but i would like to see it taken a step further.

If you were to use two  inferred cams

one facing the viewer from the screen as usual

and the other further away and to the side you could capture
the position of the users fingers in 3d
this has been done with the we bare on a hat or two dots you head

but this would be of much hire resolution and allow you to move you
also calculating the distance between to dots will not work for fingers
because you cant get two dots on a finger far enuf apart to to calculate there distance from
a single cam





                   screen
               --------------
                    cam1
                      |


                     
                       

                    user             -cam2


dose any one get what i am saying?

IR Pens / Re: How well does diffusing the LED work?

If you were to use an infer red laser pointer you would be free to move away from the screen as well as touch it!

this method would get be very shaky at 30 feet but
would work great at 10 or less which is far enuf to stop casting a shadow and or blocking someone else's view.
