Moving on with the index, the purpose of index is to show
evidence of what’s being represented, one example that would be useful for
this, would be using an image of smoke, further indicating fire. Finally, a
symbol has no resemblance between the signifier and the signified, as the
connection between them must be culturally learned. One good example would be both
numbers and alphabets, if I chose the number 7, there’s nothing inherent
regarding the number alone in any way necessary to indicate what it may
represent, hence why it must be culturally learned.

        One of my

using visual thinking to solve complex problems in everyday life”. He goes
onto discussing that we understand schematically how the visual mind works, how
our brains work is that it intentionally divides the way we see the world in 6
separate segments. The first section he describes as who and what, the second
is how much, the third is where, the fourth is when does it happen, how it

to draw, what we’re going to draw, how much we will draw, where are they going
to be displayed, using composition. Ultimately breaking down the problem and
the thought process of a creator by running this diagnostic. Furthermore, Dan
Roam explains the perfect example to convey one of the most successful and
effective visual communications through a conversation between two men in a
story he was describing referring to the first official airline from Dallas,
Houston and San Antonio, they did this by producing a map of the states,
labelling the 3 major cities and connecting them by drawing a simple line from
each dot that marked their locations, therefore creating a simple image of a
triangle within a square and from this, made the iconic logo for their idea for
the successful airline that was to be, in the end, clarifying what kind of
airline they wanted to create. With all this in mind, with the finished small
diagram of the three cities and the triangle conveying that in such a simplistic
way, it proves that
