A system for administering a field sobriety test. A central server is communicable with at least one hand held device such that information entered into the at least one hand held device is communicated to the central server. The information is stored in the central server for recall. The at least one hand held device has a screen and an input. The at least one hand held device provides a step by step checklist and at least one action test. The step by step checklist is electronically interactive utilizing the input of the at least one hand held device and has at least one validation step to confirm the correct step by step procedure is followed. The at least one validation step requires that a user enter information prior to moving to a next step. The at least one action test has at least two common occurrence buttons. The at least two common occurrence buttons are electronically interactive utilizing the input of the at least one hand held device.

A device for measuring eye movement in a human subject comprises a housing, at least one stimulator mounted to the housing, and a sensor. The at least one stimulator is configured to provide stimulus to one or both eyes of the subject. The sensor is configured to collect information related to movement of one or both eyes of the subject. The device also includes a user interface that is configured to control the at least one stimulator and display information collected by the camera.

A telestroke eye examination accessory device, a system incorporating the same, and methods of using the same, are described. The telestroke eye examination accessory device includes eyewear having a first eye well and a second eye well, a first camera positioned within the first eye well, a second camera positioned within the second eye well, a first light array having lights in each of four different quadrants in the first eye well, and a second light array having lights in each of four different quadrants in the second eye well. The system further includes a graphical user interface useful for a practitioner using the telestroke eye examination accessory device to assess the field of vision of a patient wearing the eyewear.

A method to optimize learning based upon ocular information of a subject includes providing a video camera for recording a close-up view of a subject's eye. A first electronic display shows a plurality of educational subject matter to the subject. A second electronic display shows an output to an instructor. Changes in ocular signals of the subject are processed through the use optimized algorithms. A cognitive state model determines a low to a high cognitive load experienced by the subject. The cognitive state model is evaluated based on the changes in the ocular signals for determining a probability of the low to the high cognitive load experienced by the subject. The probability of the low to the high cognitive load experienced by the subject is displayed to the instructor.

A system and associated method for computerized rotational head impulse test (crHIT) to assess the semicircular canals of the human vestibular system clinically in patients with balance disorders. The system utilizes a rotary chair combined with a head mounted VOG system with head tracking sensors. The crHIT protocol uses the same physiologic principles as the known video head impulse test (vHIT). The crHIT utilizes whole-body rotation via the chair to yield a persistent controlled, repeatable, comfortable, reliable stimulus can be delivered while recording eye movements with video-oculogaphy.

A mobile system for measuring opticokinetic nystagmus in a subject includes a display screen to provide an opticokinetic stimulus and an imaging system to record eye movement data of the subject. The mobile system is configured to compare the stimulus and the recorded eye movement data to provide objective vision acuity testing.

To determine impairment due to drugs or alcohol, an image capture component captures video of at least a head of a test subject. Cropped head images of the head of the test subject are extracted from sequential images of the video. For each cropped head image, a gaze angle of the test subject is determined from the cropped head image. The determined gaze angles are analyzed to determine horizontal nystagmus and/or angle of onset of nystagmus. A level of impairment of the test subject is determined from the horizontal nystagmus and/or angle of onset of nystagmus. A visual representation of the level of impairment of the test subject is generated on an associated display.

A system and/or method for determining human health uses a head-worn apparatus that comprises a head orientation sensor, an eye imaging device, and an electronic circuit. The head orientation sensor is configured for generating an electrical head orientation signal in response to head pitch or head yaw. The eye imaging device is configured for observing an eye feature from the sclera, cornea, iris, or pupil, and generates an eye electrical signal in response to eye position, horizontal eye movement, vertical eye movement, pupil size or eyeblinks at a plurality of times. The electronic circuit is configured for generating an ocular parameter measurement such as saccades, vestibulo-ocular reflex, vestibulo-ocular reflex cancellation, vergence, smooth pursuit, nystagmus, dynamic visual acuity, pupil size, and/or eyeblinks from the head and eye electrical signals. The ocular parameter measurement can be used to determine normal human health, a neurologic disorder, a biochemical health impairment, or a physiologic health impairment.

Method, system and apparatus (10) for capturing eye/pupil movement(s). Wearable apparatus (10) includes image capture means (12,18), a light source (16) to illuminate the eye(s). Video recordings can be stored in memory (20) and/or transmitted to a remote location. The apparatus (10) can include on-board image processing. Pupil shape and/or position can be determined e.g. from glints (28). Direction and speed of eye motion can be determined. Head movement (50) and eye motion (52) measurements can be obtained. Measurement by head movement sensors (32), body sensors (34) and/or environment sensors (38) (e.g. gravity) can be factored in to an assessment of the user's condition.

A device, system, and method for operating a nystagmus testing device is disclosed. The device comprising a camera configured to face a test subject to capture eye movements of the test subject, a start button configured to start a nystagmus routine, a front display positioned to face the test subject configured to display a visual stimulus, a rear display positioned to face a test administrator configured to display a visual tracker, and a controller configured to control movements of the visual stimulus and the visual tracker on the front and rear display, respectively, and generate data of the nystagmus routine.
