Ex 6 Visual Perception 1
I found this infographic in an article titled "Why Californians will soon be drinking water from Mexico's ocean." This simple chart shows the desalination process to get the salt out of ocean water. I think flow charts are a good example of Top-Down Visual Processing because there is an obvious sequence of eye movements. This chart entails goal bias attentional looking because the viewer starts at the beginning point of the chart and their attention flows in the direction to what they're trying to gain/learn. At each progression/circle, the viewer focuses and fixates to reach the goal. There are a variety of fixations. I think most viewers would fixate more on the larger circles of the chart, where the information is more relevant to the sought after information/goal--the outcome of the desalination process. I seem to fixate first and longer on "Ocean" then to "Reverse Osmosis," as I glimpse at the smaller circles alongside them, and then end at "Fresh Water." The same system would apply to more complex charts.
