  1. AAT-EyeCheckScreening for Fatigue Kim O’Neil Advanced Aviation Technology Ltd. Tel. +44 1483 811 311 Advanced Aviation Technology www.aatl.net

  2. Presentation • What is EyeCheck? • Application areas • How does it work? • Underlying technology • Screening Methods, Results & Issues • Benefits Advanced Aviation Technology www.aatl.net

  3. 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 www.aatl.net

  4. What is EyeCheck? Advanced Aviation Technology www.aatl.net

  5. 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 www.aatl.net

  6. Why Test? Fatigue: • Occupational Hazard • Rarely monitored, subjective • Accidents, poor decision making • Disfunctional behaviour, stress, irritation • Major risk in many responsible professions: • Pilots, ATC, Doctors, Police, Security etc. etc. • Especially where “Sleep Hygiene” is poor Advanced Aviation Technology www.aatl.net

  7. Why Test? Fatigue due to: • Lack of sleep • Disrupted sleep patterns • Stress, overwork, Illness….. 17-19 hrs without sleep - Equivalent to 0.05 BAC [Williamson AM, FeyerA-M. 2000. “Moderate sleep deprivation produces impairments in cognitive and motor performance equivalent to legally prescribed levels of alcohol intoxication.” Occupational and Environmental Medicine57:649-55. Dawson, D. and K. Reid. 1997. “Fatigue, Alcohol and Performance Impairment.” Nature388 (July 17): 235.] Advanced Aviation Technology www.aatl.net

  8. Application Areas • Measuring fatigue • Fatigue and human performance • Impact of duty times, shift patterns • Safety monitoring of personnel • Sleep hygiene, stress • Detection of drugs (pre-screening) Advanced Aviation Technology www.aatl.net

  9. 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 www.aatl.net

  10. 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 www.aatl.net

  11. 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 www.aatl.net

  12. Underlying Technology Advanced Aviation Technology www.aatl.net

  13. Underlying Technology • Able to take other measurements: • “Fatigue waves” • Oscillation of the pupil over 15 minutes • Detailed performance of pupil over time • Supports studies of human performance • Impact of sleep patterns on fatigue • Baseline task performance against fatigue • Sleep hygiene Advanced Aviation Technology www.aatl.net

  14. Methods, Results, Issues • Simple to apply, reliable and accurate • based on solid medical principles & practical use • well documented literature available • Not recommended for: • under 16’s, over 50’s • pregnant women • under medication • recent eye surgery Advanced Aviation Technology www.aatl.net

  15. Benefits • Lightweight, portable, user friendly • Non-invasive • Can sample large numbers quickly • Records & analyses subject data, results • S/W analysis programs supplied • Adaptable for many purposes, environments • “Breathalyzer” for fatigue impairment Advanced Aviation Technology www.aatl.net

  16. Summary • Easy to Use, Portable, Minimal Training • Rapid, Accurate, Reliable, Adaptable • Benchmarks Fatigue, Duty Time Schemes • Whole workforce testing possible • Performance improvement • Fitness-for-duty testing Advanced Aviation Technology www.aatl.net

  17. Benefits of Screening • Enhanced operating environment • Improved reliability, performance, productivity • Reduces incidents, accidents, risk • Reduces loss, reduces costs • Improves morale • Strong deterrence for substance abuse Advanced Aviation Technology www.aatl.net
