I’m creating a classic “Magic Wand” and trying to module the complex movement of a 5 pointed star over a 2 second window.It appears from spectral features that each window’s data is converted to one point.
When using the module, if I wave the wand around wild enough, I eventually get a point that matches with a point from the Module, and a false hit.
How do I change the module so the full 2 seconds of the window need to be a match and not just one point of it?
My data on the 3D graph looks well organized.
thank you!
@jebay1 Here you’d probably want:
- Add some more data that is ‘not 5 pointed star’. Models don’t have an ‘I don’t know what happens state’.
- An anomaly detection block to know when something weird happened and you can discard the movement.
- Use some smoothing over the signal, e.g. classify every 200ms. and if the last 3 windows were all star movement only then print the classification. The Arduino continuous motion example has some info there.
