<p>A system and method is provided for remotely and optionally transmitting data to or programming a portable information device, such as a programmable watch (14), using a visual display device, such as a CRT monitor (16). The monitor displays a sequence of changing optical patterns [30(1) - 30(10)] used to optically transmit a serial stream of data. The optically programmable watch has an optical sensor (15) which detects the sequence of optical patterns to optically receive the data stream. The optical patterns transmit machine-readable serial data 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 in alphanumeric text 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.</p> |
