Abstract: A head-mountable device can include a crown module that receives input from a user and provides localized haptic feedback to the user. A magnetic element coupled to a crown can be moved by inducing magnetic fields, and the position and/or movement of the magnetic element can be detected to provide closed-loop control of the induced magnetic fields. The haptic feedback can be effectively perceived by the user at the crown without causing the entire head-mountable device to vibrate against the head and/or face of the user.
