Image-based system to observe and document eye responses having a reflective protractor for measurement of stimulus position
First Claim
1. An image-based system to observe and document eye responses, comprising:
- a frame;
a faceplate attached to said frame, shaped to substantially conform to a subject'"'"'s face and having at least one opening oriented opposite a subject'"'"'s eyes when said subject places their face against said face plate;
at least one illumination device attached to said frame and aligned with said eye opening to illuminate a subject'"'"'s eyes when said subject places their face against said faceplate;
at least one imaging device attached to said frame and aligned with said eye openings to generate an image of a subject'"'"'s eyes when said subject places their face against said faceplate; and
a reflective protractor attached to said frame and aligned with said eye opening facing said at least one imaging device to display an image of the position of a stimulus target used by a test administrator.

Abstract
The image-based system is used to observe and document eye responses which can be used to implement the procedures defined in the Standardized Field Sobriety Test as well as the Drug Recognition Expert Program. These eye responses include pupil movement, as well as pupil size and responses, for either one or both eyes simultaneously. The system includes a headset against which the subject places their face. The faceplate has an opening through which illumination devices transmit beams of infrared light to illuminate the subject'"'"'s eyes. A reflective protractor, having a scale imprinted thereon, is mounted on the headset above the eye opening and facing the test administrator to provide an image of the stimulus target that is used by the test administrator. Two imaging devices are mounted on the headset opposite the eye opening to generate images of the subject'"'"'s illuminated eyes. The generated images are transmitted to an image recording device for storage and an image display device for display to a test administrator.

12. An image-based system to observe and document eye responses, comprising:
-
a frame; a faceplate attached to said frame, shaped to substantially conform to a subject'"'"'s face and having at least one opening oriented opposite a subject'"'"'s eyes when said subject places their face against said face plate; at least one infrared light emitting diode illumination device attached to said frame and aligned with said at least one eye opening to illuminate a subject'"'"'s eyes when said subject places their face against said faceplate; a reflective protractor attached to said frame and aligned with said eye opening facing away from said subject to display an image of the position of a stimulus target used by a test administrator; at least one camera attached to said frame and aligned with said at least one eye opening to generate an image of a subject'"'"'s eyes when said subject places their face against said faceplate and said image of the position of a stimulus target used by a test administrator, and an image display device connected to said camera for displaying said image of a subject'"'"'s eyes when said subject places their face against said faceplate and said image of the position of a stimulus target used by a test administrator. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
