aircrew information needs
Aircrew Information Needs
  • Flight Information
    • Speed, altitude, attitude etc.
  • Systems information
    • RPM, temperature, voltage, fuel etc.
  • Navigation information
    • Where am I? Where is the airport? Where is that mountain?
  • Mission Information
    • Targets, Traffic, Threats, etc
effective cockpit design
Effective Cockpit Design
  • Cockpits are designed to a happy medium

Central Executive

The Problem
  • Cockpits are static
  • Pilots’ information needs and capabilities are not
    • Performance changes with arousal
    • Modalities matter

An adaptive cockpit would have to read the pilot’s mind

reading the mind
Reading the Mind
  • Cognitive state is brain state
  • Neuroimaging techniques monitor brain state
neuroimaging techniques
Neuroimaging Techniques
  • Electromagnetic techniques
    • EEG/ERP, MEG/ERF
      • Measure electromagnetic consequences of brain activity
        • Timing of brain activity
        • Intensity of brain activity
  • Hemodynamic techniques
    • fMRI, PET, fNIRS
      • Measure changes in blood flow and oxygenation associated with brain activity
        • Location of brain activity
          • Different locations are associated with different functions
augcog and cogpit
AugCog and CogPit
  • DARPA’s Improving Warfighter Information Intake Under Stress (formerly Augmented Cognition) Program
    • Apply neuroimaging to solve human factors problems
  • Cognitive Cockpit (CogPit)
    • Joint QinetiQ/Alion/NAVAIR project to apply neuroimaging to aviation
constraints on techniques
Constraints on Techniques
  • Equipment
    • Cost
    • Size
    • Power consumption
    • “Weird Stuff”
    • Comfort
techniques of choice
Techniques of Choice
  • EEG
    • Spectral Power Density
    • Interelectrode coherence
  • fNIRS
    • Blood Oxygenation
how it works
How it Works
  • Hook the “pilot” up
calibrate
Calibrate
  • 3 levels of tracking task
  • 3 levels of Bakan task
  • 4 combinations of Bakan and Tracking

cogmon
CogMon
  • Records spectral power and interelectrode coherence
  • Produces linear model relating physiological signal to different levels of tracking and Bakan task
  • Rates subsequent recordings against model to produce judgment of pilot spatial and verbal workload in real time
atas cockpit
ATAS Cockpit
  • Low cost, maximally open source
  • Allows great flexibility to prototype “mitigation strategies”
knowledge coordinator
Knowledge Coordinator
  • Assesses pilot workload and mission context.
  • Triggers workload mitigations

mitigations

Mitigations

  • Attention
    • Declutter
    • Alerts
  • Executive Function
    • Function Automation
  • Sensory Input
    • Multimodal Cueing
  • Working Memory
    • Sequencing
does it work
Does it work?

Tests at NAVAIR are just getting underway

  • Specifics
    • Detection of cognitive state
      • Recent results from CogPit are promising
      • Actual flight tests of EEG workload monitor by other labs (AFRL, NRC Canada/U. of Iowa)
    • Mitigation Strategies
      • Too early to tell for current CogPit
      • Needs more focus
will the user accept it
Will the user accept it?

You make the call…

road ahead
Road Ahead
  • The full closed-loop technology is not ready
    • Imaging equipment is bulky, temperamental, and uncomfortable
    • Mitigations are still in development
  • Bits of the technology could be useful in the near term.
first step hypoxia
First Step: Hypoxia?
  • Poses danger to all high altitude operations
  • Factor in at least 16 mishaps (3 fatalities) in Naval aviation since 2001
    • Naval Aviation has lost 0 TACAIR assets to enemy fire since Desert Storm
hypoxia

Hypoxia

Currently mitigated with altitude chamber training

Symptoms are subtle and variable

Fundamentally strikes at cognitive ability

Current countermeasure hinges on ability of broken system to diagnose itself

hypoxia detection with fnirs
Hypoxia Detection with fNIRS
  • fNIRS passes near infrared light through the skull and measures absorption of different wavelengths
    • Oxygenated and deoxygenated blood preferentially absorb different wavelengths
    • Yields measure of both blood volume and blood oxygenation
slide25
fNIRS potentially provides the basis for a hypoxia and G-LOC warning system
  • Open questions:
    • How reliable would such a system be?
    • What do we do with the information?
take away
Take Away
  • CogPit is a platform to develop cockpits that “read the pilot’s mind” to provide the pilot with the right information at the right time
  • The full technology is still a ways off, but subsets of it may be able to provide benefits to aviators much sooner
