Checking the data sheet
http://www.analog.com/static/imported-files/Data_Sheets/AD7147.pdf

It looks like several inputs are required to register position.
However, is there an output that is proportional to pressure / contact
area? That would enable a full octave of pressure sensitivity.
Otherwise it looks like all of the sensors are pretty much on/off
only.
