RESULTS Heatmaps and gaze plots were generated for the 1 and 2-column pages and for the search and browse tasks. The following is a summary of the results: The F/E-Pattern:?There was a distinct F or E pattern for both the 1-column condition?(see Figure 1)?and left column of the 2-column condition?(see Figure 2). The pattern was exhibited regardless of whether it was a browse or search task. This pattern has been noted previously by Nielsen (2006) and Shrestha, et al., (2007).?The right column of the 2-column browse condition lacked any distinctive pattern (Figure 2), though, it is apparent that this column had more fixations in the search condition. It was suspected that the second column of the 2-column layout may elicit the similar eye movement patterns as the first column, but this did not seem to be the case. Figure 1. Heatmap of 1-Column Browse (left) and 1-Column Search (right). The circle indicates the location of the target for the search condition. Figure 2. Heatmap of 2-Column Browse (left) and 2-Column Search (right). The circle indicates the location of the target for the search condition. Fixation count throughout article:?Fixation count was the highest at the top of the article and decreased steadily down the article. This was true for both the 1-column and 2-column search and browse tasks.?To quantify this, the number of fixations for each of the 22 defined AOIs on the article were summed.?Figure 3 shows a comparison of the number of fixations by task for each layout. It can be seen that, in general, fixations decrease throughout the article. The spike in the 8th AOI for the search condition reflects the target location. Figure 3.

Browse vs. Search:?While the figures above show little difference between browsing and searching the article itself, examination of individual gaze plots (Figure 4 and 5) for each task revealed that theparticipants i
