Measuring walking speed/intensity?

Hey guys,

I'm working on a project similar to this:

I am looking for a way to measure the intensity or speed of someones walk and then with that data determine led light output. Would an accelerometer work for this? How would I measure the walking speed?

thanks!
Matt

I think an accelerometer would work. On every step you should see an increase in the magnitude of the acceleration vector (or at least a sizeable change). The time between these pulses indicate walking speed. You'll have to calibrate for how long each step is.
