I'm looking for someone to do some programming work to share, and would be interested to learn about different approaches to commissioning and tendering of work over the internet - tapping into international networks for people programming for MaxMSP, and approaches to cooperative funding of programming projects.
The idea is to make an open source/CC version of the popular HeartMath or Wild Divine heart rate biofeedback applications - but minus the cheesy displays, and new age jargon!
Technically all these apps do is track resonance in heart rate oscilations at around 0.01Hz (6 cycles per minute), that are produced when people engage in very focussed and sustained feelings of appreciation/peacefullness. Sounds crazy - but based on my own experience with these two pieces of software - it does work!!
So the idea would be to either create a Max object that does this - and would let Max folks create emotionally mediated interactives
OR create an independent app that transmits key variables via OSC.
Its also important to able to test this signal - so some type of inverse FFT that would allow users to feed in test signals and test the responsiveness.
Because heart rate data is irregularly sampled, Lomb-type approaches are recommended. Timing accuracy is critical, so it needs to be independent of the Max scheduler?
Perhaps a much simpler approach would be to convert the heart rate data to audio signal (ULF!) then feed it into a standard FFT/fiddle object - but that means having to wait a long time to fill the sample buffer if you want to measure signals at 0.001 Hz, that's a long wait (5-10 mins).
I have a modest budget of around $500-1000 AUD.
I'd like to SHARE the completed object/abstraction with others in the interactive art/design/music community - CC, Shareware license or similar.
