1. A system comprising:

  • a source of electromagnetic radiation configured to flood an active playing area with electromagnetic radiation;

    an article positioned in the active playing area and comprising a retro-reflective material, wherein the retro-reflective material is a solid component of the article or the retro-reflective material is a coating on the article;

    a sensing device configured to receive the electromagnetic radiation after being reflected from the retro-reflective material of the article positioned in the active playing area and configured to generate data based on receiving reflected electromagnetic radiation from a series of article positions, wherein the source of electromagnetic radiation and the sensing device are each in respective fixed positions; and

    a controller configured to process the data generated by the sensing device to determine whether the series of article positions correlate to a stored gesture and output a control signal to actuate an effect when the series of article positions correlate to the stored gesture, wherein the controller is configured to pre-process the data to remove interference received by the sensing device when the active playing area is in broad daylight.
