Abstract:
A method of capacitive sensing may include transmitting a first sensing signal along a first transmitter electrode among various transmitter electrodes of an input device. The method may further include obtaining, using various receiver electrodes in the input device, a first resulting signal in response to the first sensing signal being transmitted along the first transmitter electrode. The method may further include obtaining a second resulting signal from a second transmitter electrode among the transmitter electrodes. The method may further include determining, using the second resulting signal, interference along the second transmitter electrode. The method may further include adjusting, using the interference along the second transmitter electrode, the first resulting signal to produce an adjusted resulting signal. The method may further include determining, using the adjusted resulting signal, positional information regarding a location of an input object in a sensing region of the input device.
