1. A method for interpreting at least two consecutive gestures, wherein each gesture is a specified pattern of movement of an external object relative to an electronic device, the method comprising:

  • providing as part of the electronic device a sensing assembly, wherein the sensing assembly includes either (a) at least one first photoreceiver and a plurality of first phototransmitters, wherein each first phototransmitter is positioned to emit a respective portion of first infrared light away from the electronic device about a corresponding central transmission axis, wherein each central transmission axis is oriented in a respective different angular direction with respect to the others, and wherein the at least one first photoreceiver is configured to receive at least some of the first infrared light, or (b) at least one second phototransmitter and a plurality of second photoreceivers, wherein the at least one second phototransmitter is configured to emit second infrared light, wherein each second photoreceiver is positioned to receive at least some of the second infrared light about a corresponding central receiving axis, and wherein each central receiving axis is oriented in a respective different angular direction with respect to the others;

    controlling either first emissions of the portions of the first infrared light by the first phototransmitters or second emissions of the second infrared light by the at least one second phototransmitter during each of a plurality of time periods;

    for each of the plurality of time periods, generating a corresponding measured signal indicative of a respective amount of the first or second infrared light that was received by a respective one of the at least one first photoreceiver or the plurality of second photoreceivers;

    evaluating the measured signals to identify a first gesture and a second gesture;

    operating the electronic device to ignore the first gesture upon the identifying of the first gesture; and

    controlling the electronic device to take a first action in response to the identifying of the second gesture according to a first mode of operation of the electronic device.
