Claim 4:
5. The wearable system of claim 1, wherein the wearable device is a first wearable device, wherein the drive electrode is a first drive electrode, wherein the stimulation signal is a first stimulation signal, wherein the sense electrode is a first sense electrode, wherein the sense output signal is a first sense output signal, and wherein the wearable system further comprises:
a second wearable device, comprising:
drive circuitry coupled to a second drive electrode and configured to generate a second stimulation signal, the drive electrode positioned at a first location in the second wearable device for contacting a first finger of a second hand; and
sense circuitry coupled to a second sense electrode and configured to generate a second sense output signal, the second sense electrode positioned at a second location in the second wearable device for contacting the first finger of the second hand, wherein:
the first stimulation signal has a first frequency selected from a first set of stimulation frequencies; and
the second stimulation signal has a second frequency selected from a second set of stimulation frequencies, the second set of stimulation frequencies being different from the first set of stimulation frequencies.
