This is cool. I wonder if in addition to changing the current injection electrode, dynamically varying the resistance at the electrodes can help increase the resolution. Changing the resistance dynamically can change the current distribution on the surface. This can be used to change the gradient around the touch location to further refine the position. Edit: clarity and typos
