Advanced Aviation Technology Presentation What is EyeCheck? Application areas How does it work? Underlying technology Screening Methods, Results & Issues Benefits

Advanced Aviation Technology What is EyeCheck? EyeCheck™ Pupillometer –Analyses Eye Pupil Response –Employing simple medical principles –Straightforward measurement techniques –Rapid, two minute test…... Application to: –Measurement of fatigue –Detection of drugs.

Advanced Aviation Technology What is EyeCheck?

Advanced Aviation Technology What is EyeCheck? EyeCheck: –Non-invasive –Non-Gender specific –Instant results and analysis –Eliminates privacy issues –No baseline necessary –Medically peer reviewed –Easy-to-use, minimal training required

Advanced Aviation Technology Why Test? Drugs: Illegal drug use widespread in society Prescription drugs a problem too Impairment, Accidents, poor decision making Disfunctional behaviour, stress, irritation Major risk in many responsible professions: –Pilots, ATC, Doctors, Police, Security etc. etc. –Especially when under stress

Advanced Aviation Technology Why Test? Fatigue an interrelated problem too: Lack of sleep Disrupted sleep patterns Stress, overwork, Illness… hrs without sleep - Equivalent to 0.05 BAC [Williamson AM, FeyerA-M “Moderate sleep deprivation produces impairments in cognitive and motor performance equivalent to legally prescribed levels of alcohol intoxication.” Occupational and Environmental Medicine57: Dawson, D. and K. Reid “Fatigue, Alcohol and Performance Impairment.” Nature388 (July 17): 235.]

Advanced Aviation Technology Application Areas Measuring impairment Impairment and human performance Impact of shift patterns (fatigue) Safety monitoring of personnel Sleep hygiene, stress Detection of drugs (pre-screening)

Advanced Aviation Technology Application Areas Roads, Trains, Boats, Planes Pilots, cabin crew, maintenance, ATC, drivers On duty, in transit, on standby Airlines, airports, rail, maritime, road transport Police, private security Public safety, clubs Research

Advanced Aviation Technology How Does it Work? Easy to use… Simply look into the unit: A light flashes, the pupil reacts to stimuli, causing constriction followed by re-dilation. Eyecheck measures, records and evaluates this response….. (include subject data, age)

Advanced Aviation Technology How Does it Work? The eye is allowed to adapt to dark (30 secs) –EyeCheck measures initial pupil diameter A brief flash of light: –measures reflex amplitude, rate of constriction –final minimum pupil diameter, time to min. dia. EyeCheck measures real-time eye dynamics –infrared optics, collects IR light scattered by eye –10 -2 mm accuracy, 10 samples per second

Advanced Aviation Technology Underlying Technology

Advanced Aviation Technology Underlying Technology Able to take other measurements: –“Fatigue waves” –Oscillation of the pupil over time –Detailed performance of pupil over time Supports studies of human performance –Impact of fatigue/narcotics on performance –Baseline task performance against fatigue/drugs –Sleep hygiene
