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.

First claim

The invention claimed is:

1. A system comprising:
a source of electromagnetic radiation configured to continuously emit electromagnetic radiation into an active playing area;
a sensing device configured to receive the electromagnetic radiation after being reflected from a retro-reflective material of an article positioned in the active playing area and configured to generate data based on receiving the reflected electromagnetic radiation from a series of article positions; and
a controller configured to:
identify the retro-reflective material based on data indicative of a plurality of detectable retro-reflective materials stored in a memory of the controller;
determine whether the series of article positions correlate to a stored gesture based on the series of article positions; and
output a control signal to actuate an effect when the series of article positions correlate to the stored gesture.

2. The system of claim 1 , wherein the controller is configured to modify a tolerance associated with determining whether the series of article positions correlate to the stored gestured based on the identification of the retro-reflective material.

3. The system of claim 2 , wherein each detectable retro-reflective material of the plurality of detectable retro-reflective materials corresponds to a different tolerance associated with a guest associated with the article.

4. The system of claim 1 , wherein the controller is configured to interpolate between the series of article positions to facilitate determining whether the series of article positions correlate to the stored gesture.

5. The system of claim 1 , wherein the controller comprises a gesture recognition module including a plurality of pre-programmed gesture characteristics.

6. The system of claim 1 , comprising the article including the 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.

7. The system of claim 6 , wherein the retro-reflective material is designed to reflect the electromagnetic radiation back to the source.

8. The system of claim 6 , wherein the article comprises a wand.

9. The system of claim 1 , wherein the source of the electromagnetic radiation and the sensing device are located apart from one another.

10. The system of claim 1 , wherein the active playing area includes a portion of a path for a ride vehicle and the sensing device is configured to detect activity occurring in a passenger compartment of the ride vehicle when the ride vehicle is positioned on the portion of the path.

11. The system of claim 1 , 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.

12. A method, comprising:
emitting electromagnetic radiation into an active playing area via a source of electromagnetic radiation;
receiving the electromagnetic radiation at a sensing device after being reflected from a retro-reflective material of an article positioned in the active playing area;
generating data, via the sensing device, based on receiving reflected electromagnetic radiation from a series of article positions;
identifying, via a controller, the retro-reflective material based on data indicative of a plurality of detectable retro-reflective materials stored in a memory of the controller;
processing the data generated by the sensing device, via the controller, to determine whether the series of article positions associated with the article correlate to a stored gesture; and
outputting a control signal from the controller when the series of article positions associated with the article is determined to correlate to the stored gesture.

13. The method of claim 12 , comprising modifying a tolerance associated with determining whether the series of article positions associated with the article correlate to the stored gesture based on identification of the retro-reflective material.

14. The method of claim 13 , comprising:
receiving additional electromagnetic radiation at the sensing device after being reflected from an additional retro-reflective material of an additional article positioned in the active playing area;
generating additional data, via the sensing device, based on receiving the additional reflected electromagnetic radiation from an additional series of article positions of the additional article;
identifying, via the controller, the additional retro-reflective material based on data indicative of the plurality of detectable retro-reflective materials stored in a memory of the controller; and
processing the additional data generated by the sensing device, via the controller, to determine whether the additional series of article positions associated with the additional article correlate to the stored gesture based on an additional tolerance associated with the additional retro-reflective material, wherein the tolerance and the additional tolerance are different from one another.

15. The method of claim 14 , wherein the tolerance corresponds to a first age group of a first guest associated with the article, and wherein the additional tolerance corresponds to a second age group of a second guest associated with the additional article.

16. The method of claim 12 , comprising pre-processing the data generated by the sensing device, via the controller, to remove interference received by the sensing device when the active playing area is in broad daylight.

17. The method of claim 12 , comprising interpolating, via the controller, between the series of article positions to facilitate determining whether the series of article positions correlate to the stored gesture.

18. A system, comprising:
