Hi Guys,
I’m trying to find the best way to sense people within a 2m radius circle.
It’s to make second version of our drinking fountain:

that works in all directions rather than just one. The current version uses an ultrasonic sensor to sense people but I think replicating this method may be a bit clunky for 360 degrees.
Is this possible? Is OF the answer to my problems?
thanks in advance for any response!
nice project.
we use 8 ePIR sensors arranged in a circle to find people’s approximate location.

But this might still not give you the resolution you are hoping for.
If you used s SoftPot Membrane Potentiometer you could have people touch your sculpture and so know which way it should bend.
anyway, good luck.

you could try to develop a 360 tracking using this lens.
i really want to but have no time

Golan and Kyle did some work unwrapping images similar to the ones that you’d get from the kogeto http://www.flong.com/blog/2010/open-source-panoramic-video-bloggie-openframeworks-processing/ You’d need a video capture device like this: http://www.google.com/products/catalog?q=svideo+to+USB&um=1&ie=UTF-8&tbm=shop&cid=2042481280647861478&sa=X&ei=wCPbTtmzKOOM4gTcu6TpDQ&ved=0CFUQ8wIwAA to grab it but if you’re in a controlled lighting situation that could be an easy route to take. I do think the most robust solution is an array of PIR or ultrasonic sensors though.
