Patent ID: 8821286

Claim:
A method comprising: receiving, by a motion sensing controller, two calibration wireless transmissions that were transmitted from two different wireless emitters that are fixedly positioned to two different components of a wagering game system during calibration, wherein the motion sensing controller is configured to track wagering game play of a wagering game provided by a wagering game machine based on gesture recognition and pointing relative to a display configured to display the wagering game play; receiving, by the motion sensing controller, two gameplay wireless transmissions that was transmitted from the two different wireless emitters for tracking of the wagering game play of the wagering game; determining a calibration movement difference between the two calibration wireless transmissions; determining a gameplay movement difference between the two gameplay wireless transmissions; and in response to at least one of the calibration movement difference and the gameplay movement difference being unequal and a difference between the calibration movement difference and the gameplay movement difference exceeding a threshold error, outputting an indicator of at least one of a component movement and distortion of one of the two different gameplay transmissions.
