PS2 MicroModule
Integration Guide
The 4-zone FSR used in MicroModule is simply a combination of four basic FSRs arranged in a
North, South, East, West pattern. Each zone interpenetrates into the two zones on either side
of it. This overlapping of the zones allows us to determine how much force is in each zone
relative to the others. Once the relative force in each zone is known, the direction and speed of
the mouse pointer can be determined.
