Abstract

A system in accordance with present embodiments includes a source of electromagnetic radiation that operates to emit electromagnetic radiation into an active playing area. The system also includes a sensing device that operates to receive the electromagnetic radiation after being reflected from a retro-reflective material of an article positioned in the active playing area and operable to generate data based on receiving reflected electromagnetic radiation from a series of article positions. Further, the system includes a controller that operates 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.
