Footstep control

I've been trying to adapt the Andy Farnell footstep PD patch to be controlled by the wii fit balance board. This is proving to be difficult because the PD patch isn't designed to be controlled step by step but has a built in system to simulate walking.

Using the wii board to control simple footstep samples is inadequate because this does not take in to account the force/ pressure applied by the foot, or which part of the foot strikes first.

I have found an interesting paper on the subject -

If anything this may just prove that this is too complex and would probably deserve a project of its own.

This paper provides another approach using sensors built into shoes -
