Generating Position Information Using a Video Camera

An electronic device comprising:

• a processor;
• and
• storage media including instructions executable by the processor to perform acts comprising:
• receiving image information;
• identifying a plurality of reference fields of a user-manipulated device, each reference field of the plurality of reference fields including reference elements, the plurality of reference fields identified based on colors of the reference elements and a pattern of the reference elements;
• generating position information based on the plurality of reference fields, the position information identifying a position of the user-manipulated device relative to the video camera;
• and
• providing the position information to an application.

A system comprising:

• a gaming console comprising a memory including instructions and a processor to execute the instructions to perform acts comprising:
• receiving image information from one or more video cameras;
• identifying at least one reference field of a user-manipulated device based on a color of the at least one reference field, based on a shape of the at least one reference field, and based on a pattern of elements that comprise the at least one reference field;
• identifying reference information based on the at least one reference field;
• based on the reference information, generating position information that identifies a position of the user-manipulated device relative to the one or more video cameras;
• and
• controlling one or more applications based on the position information.
