1. A gaming terminal for playing a wagering game, the gaming terminal comprising: a controller; a touch surface for actuation by a player gesture associated with an input to the wagering game; a sensor array underling the touch surface to sense the motion of the gesture, the sensor array coupled to the controller, wherein the controller: converts the sensed motion to corresponding gesture data indicative of the gesture made by the player, and determines from at least a portion of the gesture data a trajectory of an intended gesture that differs from the gesture made by the player based on a criterion that includes an acceleration of at least a portion of the gesture made by the player, wherein the determination of the trajectory includes breaking the gesture into segments of sensors of the sensor array underlying the touch surface, measuring the acceleration of the gesture on each segment, and determining the trajectory based on the segment having the fastest measured acceleration; and a display coupled to the controller to display movement of an object image during the wagering game based on the trajectory of the intended gesture, wherein the touch surface includes a launch boundary defining a first zone and a second zone, wherein the gesture made by the player in the first zone is sensed and the gesture made by the player in the second zone is ignored.
