Technique for providing an indication of viewer interest in response to visual stimuli. A viewer is exposed to visual stimuli. The viewer's saccadic eye motion occurring while the viewer is being exposed to the visual stimuli are measured. The visual stimuli are displayed together with the measured saccadic eye motion that occurred while the viewer was being exposed to the visual stimuli as an indication of the viewer's interest in such visual stimuli.
