1. A wearable system for detecting gestures, comprising:
a wearable device, comprising:
drive circuitry coupled to a drive electrode and configured to generate a stimulation signal, the drive electrode positioned at a first location in the wearable device for contacting a first finger of a first hand; and
sense circuitry coupled to a sense electrode and configured to generate a sense output signal based on one or more sense signals received at the sense electrode in response to the stimulation signal, the sense electrode positioned at a second location in the wearable device for contacting the first finger of the first hand; and
a processor communicatively coupled to the drive circuitry and the sense circuitry of the wearable device, and configured for:
capturing an amplitude of the sense output signal over time, and
in accordance with a determination that first criteria are met, the first criteria comprising first amplitude and time criteria evaluated for the sense output signal, detecting a making of contact of the first finger of the first hand with a body part different from the first finger of the first hand.
