1. An electronic device comprising: a processor; a display coupled to the processor; a touch sensor coupled to the display and configured to receive a gesture through touch input, the gesture comprising a plurality of points; a gesture interpretation module coupled to the touch sensor and that, when executed by the processor: defines an oriented bounding box for the gesture; determines an amount of points of the plurality of points that are contained within the oriented bounding box; and determines that the gesture approximates a straight line based at least in part on the amount of points that are contained within the oriented bounding box; and a gesture set module configured to receive, based at least in part on a determination that the gesture approximates the straight line, a straight line gesture indication and, at least partly in response to receiving the straight line gesture indication, to perform an action.
