Abstract

A projector includes an infrared generator, an infrared camera, an infrared control module, and a controller. The infrared generator provides an infrared curtain on a screen that the projector projects an image. The infrared camera detects a selection of an icon on a control strip located within the infrared curtain. The infrared control module is in communication with the infrared generator and the infrared camera, and determines a coordinate position within the infrared curtain associated with the selection of the icon on the control strip. The controller is in communication with the infrared control module, and determines a command for the projector based on the coordinate position of the selection of the icon, and executes the command.

Claims (42)

1. A projector comprising:

an infrared generator to provide an infrared curtain on a screen that the projector projects an image;

an infrared camera to detect a selection of an icon on a control strip located within the infrared curtain;

an infrared control module in communication with the infrared generator and the infrared camera, the infrared control module to determine the location of the control strip based on a first infrared signature of a first infrared calibration tag of the control strip and a second infrared signature of a second infrared calibration tag of the control strip, and to determine a coordinate position within the infrared curtain associated with the selection of the icon on the control strip; and

a controller in communication with the infrared control module, the controller to determine a command for the projector based on the coordinate position of the selection of the icon, and to execute the command.

2. The projector of claim 1 further comprising:

an input/output interface in communication with the controller, the controller to send the coordinate position to a computer via the input/output interface in response to the coordinate position not matching coordinate positions stored within a look up table associated with the control strip.

3. The projector of claim 1 wherein commands associated with icons of the control strip are preprogrammed in the controller.

4. The projector of claim 1 wherein the infrared control module further detects a new control strip within the infrared curtain.

5. The projector of claim 4 wherein the control strip has a first infrared signature and the new control strip has a second infrared signature.

6. The projector of claim 1 wherein the infrared curtain has a specific infrared wavelength.

7. A projector comprising:

an infrared camera to detect a selection of an icon on a control strip located within an infrared curtain;

an infrared control module in communication with the infrared generator and the infrared camera, the infrared control module to determine the location of the control strip based on a first infrared signature of a first infrared calibration tag of the control strip and a second infrared signature of a second infrared calibration tag of the control strip, and to determine a coordinate position within the infrared curtain associated with the selection of the icon on the control strip; and

a controller in communication with the infrared control module, the controller to determine a command for the projector based on the coordinate position of the selection of the icon, and to execute the command.

8. The projector of claim 7 wherein commands associated with icons of the control strip are preprogrammed in the controller.

9. The projector of claim 7 wherein the infrared control module further detects a new control strip within the infrared curtain.

10. The projector of claim 7 wherein the control strip has a first infrared signature and the new control strip has a second infrared signature.

11. The projector of claim 7 wherein the infrared curtain has a specific infrared wavelength.

12. A method comprising:

detecting a control strip attached within an infrared curtain on a screen to display an image from a projector;

calibrating a location of the control strip within the infrared curtain based on a first infrared signature of a first infrared calibration tag of the control strip and a second infrared signature of a second infrared calibration tag in the control strip;

detecting a selection of an icon within the control strip;

converting the location of the selection of the icon into a coordinate within the infrared curtain;

determining a command for the projector in response to the coordinate matching a coordinate within a look up table; and

executing the command in the projector.

13. The method of claim 12 further comprising:

detecting movement of the control strip in response to the first and second infrared signatures of the first and second infrared calibration tags being located in another location in the infrared curtain;

calibrating a new location of the control strip within the infrared curtain based on the first and second infrared calibration tags in the control strip; and

storing a new look up table mapping new locations of icons within the control strip to commands of the projector.

14. The method of claim 12 further comprising:

sending the coordinate to a computer in response to the coordinate not matching a coordinate within a look up table.

15. The method of claim 12 further comprising:

storing the look up table mapping locations of icons within the control strip to commands of the projector.

16. The method of claim 15 further comprising:

receiving a program control strip signal;

removing a command associated with an icon in the control strip from the look up table in response to a delete command request; and

adding a command associated with the icon in the control strip to the look up table in response to an add command request.

17. The method of claim 12 wherein detecting the control strip comprises:

detecting a first infrared signature of the first infrared calibration tag and a second infrared signature of the second infrared calibration tag in the control strip.

18. The method of claim 12 further comprising:

detecting a new control strip in the infrared curtain, wherein the control strip has a first infrared signature and the new control strip has a second infrared signature.
