- Disuse of automation
Six pitfalls of automation: Describe pitfall 1: Lack of situation/mode awareness
Unsafe situations may occur because the operator:
- Does not understand what is going on and does not know what to do
- Is not aware of the automation mode
- “The perception of the elements of the environment within a volume of time and space
- the comprehension of their meaning, and
- the projection of their status in the near future”
= Knowing what is going on so you can figure out what to do
Describe situation awareness global assesment technique (SAGAT):

Assess participants knowledge of what was happening at the time of the freeze.
Compare to objective data on what was actually happening

Six pitfalls of automation: Describe pitfall 6: Disuse of automation
- Causes: False alarm/irrelevant advice from a decision aid
- Operator’s general attitude towards automation
What is the catch 22 about supervisory control?
The human supervisor needs experience about emergency situations, but his task is to avoid emergencies = The human supervisor is “trapped”
ex, key locked inside car: To open car, need keys. To have keys, need to open car.
Describe the Roseborough dilemma:
- Why do we need the human supervisor in complex control systems?
- Answer: To complement the machine for functions that are not modelable (such as emergencies/unexpected events)
- Human supervisors sometimes make mistakes; therefore they might need a decision aid
- However, the decision aid needs a model!
- (and if such a model would be available, then why not automate the decision implementation?)
What is the common way of reasoning when it comes to Bainbridge’s ironies of automation?
Human operator is slow, unreliable and inefficient. Therefore the human operator should be eliminated from the system by means of operator.
Describe Bainbridge’s ironies of automation
- Irony 1: Designer errors can be a major source of operating problems (operator errors become design errors)
- Irony 2: Human supervisor is left to do difficult tasks which the designer cannot think how to automate
- Irony 3: When manual take-over is needed there is likely to be something wrong, and the operator needs to be highly skilled (while actually deskilling has occured)
- Irony 4: The human supervisor has lack of feedback and experience about unusual situations (catch 22)
- Irony 5: “After three decades of highly prolific research on human vigilance, we are still making the same seemingly contradictory statement: a human being is a poor monitor, but that is what he or she ought to be doing”
- Irony 6: Computer is introduced because of speed, accuracy, and the ability to handle many complex operations. The human has been given an impossible task because he cannot monitor all computer’s decisions in real time
- Irony 7: The job of automation supervisor is one of the worst types. It is boring but responsible, and there is no opportunity to acquire or maintain the qualities required to handle the responsibility.

Four stages of automation:
What steps are involved in stage 3: Decision and action selection?
Low level to high level (the computer…):
- Offers no assistance
- Suggests alternative ways
- Selects one way to do the task…
- …And executes the task if human approves
- …And restricted time veto before automatic execution
- …Executes automatically then informs the human
- …Executes automatically then informs the human if asked
- Selects the method, executes the task, and ignores the human
What does the ‘All-or-none fallacy’ mean?
Even highly automated systems, such as electric power networks need humans for supervision, adjustment, maintenance, expansion and improvement. Therefore one can draw the paradoxical conclusion that automated systems still are man-machine systems, for which both technical and human factors are important
Four stages of automation:
What steps are involved in stage 4: Action implementation?
Low level:
- Human executes task by means of hand/voice
High level:

- Inappropriate algorithms for variations in operating conditions (e.g. autopilot in storm)
- Hardware malfunction
A higher level of automation is justified when…
- The risk (cost multiplied by probability of automation failure) is low
- The situation is time-critical (that is, no reliable response can be expected from the human)
Mention some design considerations in automated systems:
- Use knobs & dials principles (stimulus response, compability, redundancy, shape coding etc)
- Present salient feedback/warning about automation (status, actions, failures, intentions)
- Take into account mental workload; especially regarding emergency situations
- Remember that false alarms cause disuse. Carefully consider the decision threshold
- Use simulator-based training (to mitigate: catch 22 of supervisory control, deskilling, miscalibrated trust)
- Minimize cognitive overhead: automation should be easy to turn on and off
- Beware of the all-or-none fallacy. Instead, think in terms of levels and stages of automation
- Decision aids may be inappropriate for direct transducing of instructions (Roseborough dilemma)
- Consider presenting meta-information (plant health indicators, likelihood alarms, configural displays, semantic mapping)
