One of the project owners here. I've used the capsense arduino library a long time ago and it's decent when you don't need the accuracy. I found that the sensor values were affected by the environment quite a bit e.x. I'd have to recalibrate everything if the project was being used in a room with a carpet which affected the body charge. Maybe you found a way around it?

Re: the sensing method, they're similar in the sense that both the avr and mgc3130 detects a change in capacitance to figure out the position. But the mgc3130 controller can detect capacitance changes in the femtofarad range.
