Better Pedometer - HELP NEEDED!

Hello,
one note about your "ringing": it is maybe because of the pass-band filter. Have you tried with a low pass instead? Or can you just remove the filter altogether?

It would be interesting to see what it looked like without the buffering and pipeline and was just sequential.

Yes, I asked students to do that but they didn't have enough time. I agree that the buffers are not needed.

The approach the Bangle currently takes is very similar

Peak detectors are somewhat similar. The main issue is adapting to a signal where amplitude can change quickly. There are also other approaches than peak detection, like analysis in frequency, wavelets, or even machine learning, but I don't think they are suitable for an embedded device like a smartwatch.

If you could build a framework around those test cases above then I think we would have what we need.

Yes, I'll set it up and post the link here. I'll try to do it next week.
