calculate the speed of changing???


    Jul 26 2006 | 5:49 pm
    hi everybody,
    i use sensors on a body ....
    i would like know if possible to calculate the speed of a float changing.
    when the dancer is calm,my sensor send me a value around a float (for exemple the sensor send me :0.5,0.51,0.49....when dancing,i receive value very different ex:0.29,0.90,0.1....etc. how can analyse for having one value (0. for calm and 1.for agitated for exemple) representing the speed of this action ???
    thanks by advance ans sorry for my english:)

      Hello Max,
      I am doing the same thing at the University of Edinburgh. If you want we can exchange knowledge on the subject.
      meanwhile I think you can use the timer to count the time between two events, two changes over time.
      Generally talking that might be extremly tricky to describe movement.

      Hi Max,
      check out tl.velocity from the tl.objects:

      If your sensor is outputting values at a consistent rate, how about
      looking at the standard deviation? It'll be low when calm, and high
      when agitated. Andrew May wrote some objects that do this.

      at your own risc, perhaps you could try a very simple object i wrote
      to calculate this :
