Week 1: Visual Coding Exercise ๐Ÿ‘€

The first MEDA 102 tutorial required us to research how telegraphs were sent (both visual and electric). We were to devise a way to send a random message that was provided, to another group via Morse Code(or a code system that you think may work better/easier for your purpose). In doing so we prepared 2 keys, one for the coder (sender) and another for the decoder (receiver). We took turns from a considerable distance and recorded the results. We decided to use the Morse Code system and convert it into physical and visual movements and signals.

Roles were taken by each person within the group whereby we had 3 members. When sending the message one member had the worded message in hand and notified each letter that was in the sentence one at a time. Whilst doing so, another member of the group was assigned the role of reading the letter’s Morse Code combination to lastly the actual visual coder where they performed the visual movement aiding the message. Wide spread arms conveyed dashes and movements of hands closer to the torso depicted the dots.

We received the message “SOS SOS CQD CQD we are sinking fast”

The key we received gave the impression of great difficulty but after analyzing for some time we noticed that each symbol was relatively simple to convey by the coder to our group. upon researching this message, this is believed to have been a majority of the final wireless message sent from the Titanic. The circumstances in which this message from the Titanic was sent was clearly chaotic, many lives were at risk and it was up to this form of communication in codes to be carefully decoded for any chance of rescue.

Overall I agree that the group we were communicating with had a much more efficient and clearer system of visual coding, I believe this because for each letter of their coding system an individual movement was used to convey each letter of the alphabet. This differed from our system where Morse code utilises only dashes and dots resulting in a disorientated interpretation where the decoder can easily misread the content.

The most difficult part of the exercise I believe is creating a simple and effective way of visual communicating that the decoder can understand. Also, the coder should be mindful of the difficulties in decoding visual messages and make sure that the other party has whole heartily understood the symbol and then carry on in sending.
