Generating position information employing an imager
First Claim
Patent Images
1. A method comprising:
- receiving image information from an imager;
identifying at least one passive reference field of a user-manipulated device based on one or more colors and shapes that comprise the at least one passive reference field, the at least one passive reference field reflecting light in a diffractive pattern;
determining identified reference information based on the at least one passive reference field;
generating position information based at least in part on the identified reference information, the position information expressing a position of the user-manipulated device relative to the imager, the position information generated at least in part by mapping the position of the at least one passive reference field to one or more fixed reference points; and
controlling an application based on the generated position information.

Abstract
An application control approach using generated position information of a control device and adapted for use with a display, such as a monitor or TV, is disclosed. The control device may be conveniently held by a user. An imager is employed to image the control device to detect reference fields and generate position information. This information is used by the control device to control an application.

10. A method comprising:
-
receiving image information from an imager; identifying at least one reference field of a user-manipulated device based on one or more diffractive patterns that comprises the at least one reference field; determining identified reference information based on the at least one reference field; generating position information based at least in part on the identified reference information, the position information changing in response to movement of the user-manipulated device relative to the imager, the position information generated at least in part by detecting movement response of the one or more diffractive patterns; and controlling an application based on the generated position information. - View Dependent Claims (11, 12, 13, 14, 15)

16. An entertainment control system, comprising:
-
an imager; a user movable object having one or more diffractive patterns that comprise at least one reference field; a control device coupled to receive image information from the imager, the control device including processing circuitry for identifying the at least one reference field of the movable object based on the one or more diffractive patterns that comprises the at least one reference field;
determining identified reference information based on the at least one reference field;
generating position information based at least in part on the identified reference information, the position information changing in response to movement of the object relative to the imager, the position information generated at least in part by detecting movement response of the one or more diffractive patterns; and
controlling an application based on the generated position information. - View Dependent Claims (17, 18, 19, 20)
