| Zusammenfassung: | Disclosed is method for compensating for variation in the capacitance between multiple capacitive sensors. Prior to sensing operations, baseline capacitance values can be acquired for all sensors. A correction factor can be calculated based on such baseline values. During sensing operations (run-time), variations in capacitance from baseline values can be modified by appropriate correction factors. Sensitivity between sensors can thus be made more uniform. |
