Finger pinch detection

A system comprising:

• a watch band;
• a watch body that includes a display and one or more sensors;
• one or more electrodes coupled to the watch body;
• and
• a controller in communication with the watch body and the one or more electrodes, the controller being configured to:
• cause at least some of the one of the electrodes to transmit a signal, each electrode being driven at an assigned frequency;
• detect an amount of the transmitted signal at at least one of the one or more electrodes, wherein the amount of detected signal surpasses a specified minimum threshold amount;
• and
• based on the amount of detected signal surpassing the specified minimum threshold amount, determine that at least two fingers of a user's hand are touching each other according to the detected amount of transmitted signal received at the electrodes using a frequency assigned to each finger.
