Normalizing capacitive sensor array signals

摘要

An embodiment of the present invention is directed to a method for reporting position information. Position information received from a plurality of capacitive sensors in an array of capacitive sensors is adjusted based on predetermined adjustment values to generate adjusted position information. Each predetermined adjustment value is associated with at least one of the plurality of capacitive sensors. A signal representative of the adjusted position information is generated. In another embodiment, the sensitivity of at least one of the capacitive sensors is adjusted based on the position of the at least one capacitive sensor within the array.

1. A method for reporting position information, the method comprising:
adjusting position information received from a plurality of capacitive sensors in an array of capacitive sensors based on predetermined adjustment values to generate adjusted position information, wherein each predetermined adjustment value is associated with at least one of the plurality of capacitive sensors, and wherein each predetermined adjustment value is derived from a distance between the at least one of the plurality of capacitive sensors and a connection of the array of capacitive sensors; and generating a signal representative of the adjusted position information.
