1. An electronic device comprising:
a body that includes a display and one or more sensors;
one or more electrodes coupled to the body, at least two of the electrodes being positioned on different fingers of a user's hand; and
a controller in communication with the body and the one or more electrodes, the controller being configured to:
cause at least one of the one or more electrodes to transmit a signal, each electrode being driven at an assigned frequency;
detect a frequency of the transmitted signal received at at least one of the one or more electrodes;
based on the frequency of the detected signal, determine which fingers of the user's hand are currently touching each other according to the detected frequency of the transmitted signal received at the electrodes on at least two of the user's fingers; and
generate a representation of at least those fingers that are determined to be touching for presentation to the user.
