An eyeglass recorder includes multiple scene cameras for respectively recording frontal scenes along the viewer's horizontal line-of-sight and depending scenes at approximately a 45° angle downwardly from the viewer's horizontal line-of-sight. The viewer's eye movement is concurrently monitored to differentiate between the viewing of the recorded frontal and depending scenes and to detect saccadic eye motion for assessment of the viewer's level of interest in the viewed scenes.
