The goal of our assignment was to formulate a system of long-distance communication (~200 yards, beyond the useful range of a human voice) that is:
(please note that 'safe for those involved/observing' is not included)
Within these parameters, two basic types of systems are allowed: an alphabetical scheme in which each discrete signal refers to a Roman letter, or an logogramic scheme, in which each signal refers to an idea or short phrase.
In lieu of an alphabet-based communication scheme, our team opted for a phrase-based system. We felt an alphabetic system would be too prone to interference and signal loss ("noise") given the conditions of the event.
The system itself involves the use of a 6 x 6 grid, with each collumn/row assigned a color. To designate a specific phrase, the Sender determines which two colors match it's coordinates (for example, "This Is My Boomstick" would be Green left, Blue right) and then holds aloft a pair of poles with the necessary colors attatched. The Receiver then observes the colors, and locates the appropriate phrase on the grid. The Reciever then holds a single bare pole aloft to indicate proper receipt of message.
|Medic||This Is My
From the end of the Receiver, a single stationary pole indicates acknowledgement, while two waved poles indicates confusion.
