Abstract
A user interface feedback apparatus includes an operable element, a sensor, a processing unit, and a tactile control module. The operable element has a two-layer structure made up of a conductor and an insulator. The sensor detects, in the form of user contact information, at least a user contact position with respect to the insulator of the operable element. The processing unit acquires the detected information from the sensor, and determines parameters for an electrical signal to be output to the conductor. The tactile control module controls the frictional force between the insulator and the user by outputting to the conductor an electrical signal regulated by the parameters determined by the processing unit.
