5.12 Balance automation and human control

1.

Humans better at:

• Sense low level stimuli
• Detect stimuli in noise
• Recognize constant patterns in varying situations
• Sense unusual and unexpected events
• Remember principles and strategies
• Retrieve pertinent details a priori
• Draw on experience and adapt decisions
• Select alternatives
• Reason inductively; generalize from observations
• Act in emergency or novel situations
• Apply principles
• Make subjective evaluations
• Concentrate on important tasks when overload occurs
• Adapt physical response

2.

Machines better at:

• Sense stimuli outside human range
• Count or measure physical quantities
• Store quantities of coded information accurately
• Monitor specified (and infrequent) events
• Make rapid and consistent responses to input signals
• Recall quantities of detailed information accurately
• Process quantitative data
• Reason deductively; infer from principles
• Perform repetitive preprogrammed actions reliably
• Exert high forces
• Perform simultaneous activities
• Maintain operation under heavy load
• Maintain performance over extended periods of time
