Relative and absolute values …

I’ll publish some interesting information about a research project where we, amongst other, compared pictures with people, and then the same picture but now without people.

PaperSense with - without people in a picture.
PaperSense; with – without people in a picture. The difference between the left and the right picture is significant. The left picture got 472 in attention and the right only 131 – a drop to 28%. The heat maps though make it look that the right picture was paid much more attention to.

Eye-tracking was used to capture the differences. As the picture above shows, much focus is spent on the person in the picture.
But the heat maps, as the overlays with green to red colours, are called, just show the relative difference. There can be a substantial difference between two pictures showing similar heat maps, but I will note the figures of the total amount for each picture.
The picture with the person attracted up to three times more attention in total.
