Capacitive foot presence sensing for footwear

There is described a method for controlling active footwear, the method comprising: receiving a time-varying sensor signal from a capacitive sensor that is coupled to an article of footwear, wherein the capacitive sensor is configured to sense information about a position of a foot as the foot enters or exits the article; and using a processor circuit: identifying a time-varying morphology characteristic of the time-varying sensor signal; comparing the identified time-varying morphology characteristic to a template; and based on the comparison, providing an indication that the foot is present in or absent from the article. There is also described an apparatus for controlling active footwear.
