A UI (user interface) for natural gestural control is an electromechanical device that receives user inputs in order to provide an enhanced list and grid navigation experience. In various illustrative examples, the UI includes a touch sensitive surface assembly for receiving a finger or other user input device. A sensor array, which is located beneath the touch sensitive surface assembly, is used to determine a position of the finger on the touch sensitive surface assembly. A single mechanical, momentary contact switch is activated by the sensor array in response to receipt of the finger so that both gestural analog and momentary digital inputs are accepted from the user through the user input device. In some examples, both auditory and tactile feedback it provided to the user when momentary digital inputs are accepted.
