Abstract
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.
Claims14
An eyeglass recorder selectively attachable to conventional eyeglasses for recording visual stimuli presented to and discernable by a subject wearing the eyeglasses and for assessing the level of interest in the stimuli presented to the subject, comprising a clip cam member having at least two scene cameras for recording the visual stimuli without using eye reflected illumination, and at least one eye motion camera, with a first scene camera having a forwardly directly field of view substantially along the subject's horizontal line of sight and a second scene camera having an angularly directed field of view with respect to the subject's horizontal line of sight, the eye motion camera being focusable on a side of the subject's eye, said scene cameras being adapted for recording the stimuli as viewed by the subject, said eye motion camera being adapted for concurrently recording eye movement as a function of eye engagement with the visual stimuli with the degree of eye engagement being indicative of the subject's level of cognitive interest in the stimuli viewed.
An eyeglass recorder adaptable for attachment to conventional eyeglasses for recording visual images perceivable by a subject wearing the eyeglasses for assessing the level of interest in the images viewed by the subject, comprising a clip cam member having at least two image recording cameras, and at least one eye motion recording camera, with a first image recording camera having a forwardly directed field of view substantially along the subject's horizontal line of sight and a second image recording camera having a downwardly directed field of view from the subject's horizontal line of sight, the eye motion camera being focusable on a side of the subject's eye to detect and record the subject's saccadic eye motion as a function of eye engagement for assessing the subject's level of interest in the respective images viewed.
