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 sensing device configured to receive reflected radiation from an article when the article is disposed at a plurality of positions in an area, wherein the article comprises a material designed to filter radiation wavelengths outside of a range to predominantly reflect radiation back to a source of radiation without reflecting other radiation having the radiation wavelengths outside of the range; and
a controller comprising one or more processors configured to output a control signal to an effect device that generates an effect based on the plurality of positions correlating to a stored gesture.

2. The system of claim 1 , wherein the reflected radiation includes radiation reflected from a retroreflective material of the article when the article is disposed at the plurality of positions.

3. The system of claim 1 , comprising the article.

4. The system of claim 1 , wherein the controller is configured to:
identify a retroreflective material associated with the article based on a frequency of the reflected radiation; and
determine whether the plurality of positions correlate to the stored gesture based on the identified retroreflective material.

5. The system of claim 1 , wherein the reflected radiation comprises radiation being reflected from a solid component of the article or a coating on the article.

6. The system of claim 1 , comprising the source of the reflected radiation.

7. The system of claim 1 , wherein the controller is configured to interpolate between the plurality of positions at a plurality of times to facilitate determining whether the plurality of positions at the plurality of times correlate to the stored gesture.

8. A method, comprising:
receiving, via a sensing device, reflected radiation from an article when the article is disposed at a plurality of positions in an area;
identifying a frequency of the reflected radiation;
generating, via the sensing device, data based on the reflected radiation;
determining, via a controller, that the plurality of positions correlates to a stored gesture based on the data;
modifying, via the controller, a tolerance associated with determining whether the plurality of positions correlate to the stored gesture based on the frequency; and
outputting, via the controller, a control signal to actuate an effect device that generates an effect based the plurality of positions correlating to the stored gesture.

9. The method of claim 8 , comprising emitting radiation into the area via a source of radiation.

10. The method of claim 9 , wherein the article is configured to reflect the radiation towards the source of the radiation.

11. The method of claim 8 , comprising determining, via the controller, that the plurality of positions correlates to the stored gesture in response to determining that a timeframe corresponding the plurality of positions is less than a threshold timeframe.

12. A system, comprising:
a sensing device configured to receive reflected radiation from an article when the article is disposed at a plurality of positions in an area, wherein the article comprises a material designed to filter radiation wavelengths outside of a range to predominantly reflect radiation back to a source of radiation without reflecting other radiation having the radiation wavelengths outside of the range;
an effect device configured to generate a first effect, a second effect, or both; and
a controller comprising one or more processors and one or more tangible, non-transitory, computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to:
output a control signal to actuate the effect device to generate the first effect, the second effect, or both, based on the plurality of positions correlating to a first stored gesture of a plurality of stored gestures, a second stored gesture of the plurality of stored gestures, or both.

13. The system of claim 12 , wherein the one or more processors are configured to:
identify the plurality of positions based on a frequency of the reflected radiation; and
determine whether the plurality of positions corresponds to the first stored gesture of the plurality of stored gestures, the second stored gesture of the plurality of stored gestures, or both.

14. The system of claim 12 , wherein the reflected radiation includes radiation being reflected from a retroreflective material of the article when the article is disposed at the plurality of positions in the area.

15. The system of claim 12 , wherein the reflected radiation comprises radiation being reflected from a solid component of the article or a coating on the article.

16. The system of claim 15 , wherein the article is configured to reflect the radiation towards a source of radiation.

17. The system of claim 15 , wherein the controller is configured to pre-process the received reflected radiation to remove interference received by the sensing device when the area is in broad daylight.
