1. A computer-implemented method comprising: detecting a contact with a touch input device of an electronic device, wherein the touch input device is configured to receive touch input from one or more fingers and determine an electrical resistance associated with each of the one or more fingers providing the touch input; identifying at least one finger of the one or more fingers associated with the detected contact based on the determined electrical resistance, wherein each finger is identified based on a characteristic electric resistance corresponding to the respective finger as determined by the touch input device; determining a finger-specific command associated with the contact from the at least one identified finger, wherein the finger-specific command is determined based at least in part on each finger identified based on the characteristic electric resistance; and performing the determined finger-specific command.
