Abstract
Eye fixation patterns were explored for sixty adult subjects, each of whom viewed one of three stimuli, either in a three-dimensional model format or in a two-dimensional photographic format. The stimuli consisted of one symmetrical and two asymmetrical color representational drawings displayed in the form of a photograph or of a model. Total fixation times (in ms) were computed for seven portions of each stimulus: top, bottom, left, right, foreground, middle ground, and background. Results indicated that for all stimuli, subjects viewing the 3-D model spent significantly more time fixating the foreground and significantly less time fixating the background than subjects viewing the 2-D photograph. For the two asymmetrical stimuli subjects in the two groups differed significantly in their fixation patterns for the left/right variables. It was concluded that eye fixation patterns vary as a function of dimensionality.
