REMOTE-CONTROL DEVICE AND CONTROL SYSTEM AND METHOD FOR CONTROLLING OPERATION OF SCREEN
First Claim
1. A control system for controlling an operation of a screen having a first geometric reference, the control system comprising:
- a marking device displaying a first pattern associated with the first geometric reference on the screen; and
a remote-control device obtaining a first signal from the screen, wherein;
the first signal represents an image having a second geometric reference and a second pattern associated with the first pattern;
the second pattern and the second geometric reference have a first geometric relationship therebetween; and
the remote-control device uses the first geometric relationship to transform the second pattern into a third pattern, and calibrates the first geometric reference according to the third pattern for controlling the operation of the screen.

Abstract
A control system for controlling an operation of a screen having a first geometric reference includes a marking device and a remote-control device. The marking device displays a first pattern associated with the first geometric reference on the screen. The remote-control device obtains a signal from the screen. The signal represents an image having a second geometric reference and a second pattern associated with the first pattern. The second pattern and the second geometric reference have a first geometric relationship therebetween. The remote-control device uses the first geometric relationship to transform the second pattern into a third pattern, and calibrates the first geometric reference according to the third pattern for controlling the operation of the screen.
