Abstract: A method for a wearable computing device is presented. The wearable computing device includes one or more radio frequency (RF) antennas that are driven to expose a first body part of a user to an E-field. The first body part of the user located within a threshold distance of the RF antennas when the wearable computing device is worn by the user. Movement of the first body part of the user is determined based on changes in electrical conditions at the RF antennas over time. Movement of a second body part of the user is inferred based on the determined movement of the first body part, the second body part being located outside of the threshold distance of the RF antenna. The first and second body parts are coupled via interconnective tissues. An indication of the inferred movement of the second body part is output.
