Claim 11:
12. A method comprising:
receiving a sensor signal from a sensor that is coupled to an article of footwear, wherein the sensor signal includes information received over time about a change in an electric field in a foot-receiving cavity of the article of footwear by the sensor and a characteristic of the electric field in the foot-receiving cavity of the article of footwear is influenced by a proximity of a foot to the sensor while the foot is disposed inside of the foot-receiving cavity of the article of footwear; and
using a processor circuit:
detecting a donning event using the sensor signal, the donning event corresponding to a change in the sensor signal from a first reference value to a second reference value, wherein the first reference value corresponds to the article of footwear being unoccupied by the foot and the second reference value corresponds to the article of footwear being occupied by the foot;
following the donning event, detecting fluctuations in the sensor signal, wherein the fluctuations include respective changes in magnitude of the sensor signal by an intermediate magnitude amount, wherein the intermediate magnitude amount is at least a specified threshold magnitude change amount and is less than a magnitude difference between the first and second reference values; and
based on the fluctuations as detected, determining a step count or a step interval.
