Abstract
A system and method is provided for remotely and optically programming a portable information device, such as a programmable watch, using a visual display device, such as a CRT monitor. The monitor displays a sequence of changing optical patterns used to optically transmit a serial stream of data. The optically programmable watch has an optical sensor which detects the sequence of optical patterns to optically receive the data stream. The optical patterns transmit machine-readable information that can be detected by the optical sensor, but no meaningful information to a user. The visual display device therefore also displays a human-readable image that explains to a user the sequence of optical patterns being used to transmit the data stream. The human-readable image is displayed in a manner that renders it undetectable by the optical sensor of the programmable watch.
