Abstract
A cooking appliance includes a plurality of electrically controlled heating elements operable to elevate a temperature of food items. A user interface includes a touch-sensitive circuit that is operatively-connected to an external surface of the cooking appliance for altering operational settings of the electrically controlled heating elements. An electrovibration feedback circuit is coupled to the external surface that generates a vibratory feedback that is sensible by the user's finger at the external surface in response to adjustments of the operational settings. The electrovibration feedback circuit creates an electrostatic force on the user's finger that simulates friction between the user's finger and the external surface.
