Abstract:
1. A method for visually transmitting auxiliary data from a monitor of a computer system to a hand-held device, comprising: calculating on the computer system a horizontal frequency of the monitor to determine how to broadcast auxiliary data; manipulating the hand-held device so that an optical detector of the device is oriented toward the monitor; selectively initiating the execution of an application program available on the computer system that displays a visual image on the monitor that broadcasts the auxiliary data from the visual image as a result of the use of the computer system by a user of the hand-held device; receiving the auxiliary data on the hand-held device via the optical detector; processing the auxiliary data on the hand-held device; and providing promotional opportunities to the user of the hand-held device from reception and processing of the auxiliary data.
