Classification: CPC G  H | IPC G  H

Claim 0:
1. A circuit for a device, the circuit comprising:
a first passive electrode configured to be placed at a first location on the device;
a second passive electrode configured to be placed at a second location on the device, the first location and the second location being different locations on the device, the first passive electrode and the second passive electrode being configured to sense a variation in an electrostatic field in response to a user interacting with the device;
a sensor coupled to the first passive electrode and the second passive electrode, the sensor configured to detect a differential potential between the first passive electrode and the second passive electrode; and
a processing circuit coupled to the sensor, the processing circuit configured to determine whether the user is interacting with the device using a left hand or a right hand, the determining based on data received from the sensor corresponding to the differential potential.
