The method includes detecting a plurality of sub-gestures (e.g., simple gestures provided by a target located proximate to the system) via the array of optical sensors. The sensors generate signals based upon the detected (e.g., received) sub-gestures and transmit the signals to a processor of the gesture sensing system. The processor processes the signals to obtain data associated with the sub-gestures and analyzes the sub-gesture data to determine if the sub-gestures collectively constitute a gesture (e.g., complex gesture). When the analyzing indicates that the sub-gestures collectively constitute a complex gesture, the gesture sensing system detects the complex gesture. ## Claims ### Claim 1 A method for gesture determination via an electronic system, the method comprising: detecting a plurality of sub-gestures via a plurality of sensors of the electronic system;
