4-Zone Mouse Sensor
Integration Guide
The 4-zone FSR 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.
