We decided to keep it simple, because the simpler the concept is, the easier the practical work will be. We used four different cylindrical sticks for alphanumeric characters and a black metallic stick to signalize space.

As it can be seen in the visual representation above, different colors symbolize different groups of characters. The moves (that is, signs) for every alphanumeric character were randomly chosen to make it easier for both the transmitter and receiver to remember them. The same moves were repeated for different sticks; one sequence of moves was repeated for vowels and numbers, and another one for first six consonants. Then, a combination of the two sticks was used for the last nine consonants.

In the first sequence for numbers and vowels, random moves were chosen for the characters; however, it was important to remember the flow of the sequence. For example, holding the pink stick with your right hand, it signalizes E, and holding the yellow sticker in the same position signalizes the number 2 (both signalize the second member of the sequence, except for 0 in numbers which is considered a separate member).  In the second sequence, same technique was applied. For example, pointing out at your left shoulder with the blue-colored stick signalizes B and holding the black sticker in the same position signalizes K. The moves and their signals are shown below.

It is important to note that we agreed Gjorgji to be the transmitter and Yero the receiver, so Gjorgji signalized each character for documentation, such that during the competition, it would be easier for Yero to be more familiar with the move Gjorgji makes.

For the last nine consonants of the alphabet, a combination of two sticks was applied to signalize each character; these were black and blue-colored stick. Except for Q, R and Z which were random moves, for S,T,V,W,X,Y we decided to actually show each character visually. Out of these, only W and X were shown in its original position, whereas the other ones facing the ground (that is, being inverted). A visual representation is shown below.

The system was easy to be remembered such that the sentence can be easier transmitted when one has to combine the different moves. However, during the competition, we realized that some character can be incorrectly signalized – such as R and Y, when Gjorgji transmitted R as Y putting the blue-colored stick a bit up than it was supposed to be – and we did not think of a way to signalize a repetition of a word or a character when the receiver is not sure which character is actually being transmitted. For future improvements in the system, we should think of implementing this improvement for full system functionality.
