That's an interesting call, I'm just concerned about the chances of hitting in-between wires but I guess if each track was wide enough I could put each track almost butting up to each other so there's no 'dead space'...
So I could make the tracks out of 2 layers of velostat for the pressure contact and criss-cross them to give location.
Thanks!
Yes, track width and density will determine resolution and hence the number of I/O needed. Actual wires contacting would give a definite on/off signal. IIRC, velostat gives you more of an analog variance depending on pressure. This may not be enough to definitively switch a digital input - requiring more signal conditioning.
