Abstract: An electronic device is disclosed. In some examples, the electronic device comprises a mechanical input configured to rotate in a first direction about a rotation axis in response to a first input at the mechanical input. In some examples, the electronic device comprises a mechanical input sensor coupled to the mechanical input and configured to sense a rotation of the mechanical input about the rotation axis. In some examples, the electronic device comprises a mechanical input actuator coupled to the mechanical input and configured to rotate the mechanical input in a second direction about the rotation axis. In some examples, the mechanical input comprises a shared driving and sensing segment. In some examples, the mechanical input sensor is configured to sense the rotation of the mechanical input at the shared driving and sensing segment. In some examples, the mechanical input actuator is configured to generate magnetic fields for rotating the mechanical input at the shared driving and sensing segment. In some examples, the mechanical input is further configured to translate along the rotation axis in response to a second input. In some examples, the mechanical input actuator comprises at least one piezoelectric element configured to allow the mechanical input to translate along the rotation axis. In some examples, the mechanical input actuator comprises at least one piezoelectric element configured to rotate the mechanical input in the second direction about the rotation axis.
