A system and method for utilizing a gesture-based user interface. A system includes an operator input device and a processor. The operator input device detects gestures and multiple simultaneous touch points. An input area of the operator input device includes a plurality of gesture detection zones. The processor is coupled to the operator input device. The processor executes a gesture recognition software program that processes inputs from the input device. The gesture recognition program causes the processor to recognize a primary gesture and a simultaneous secondary gesture, and to perform a processing function based, at least in part, on the primary gesture and a gesture detection zone in which the secondary gesture is detected.
