Task 8 Trust me Flashcards
Human-machine interaction
Humans assisting machines
- Training
- Explaining
- Sustaining
Machines assisting humans
- Amplifying
- Interacting
- Embodying
Aspects that companies want to improve
- Flexibility
- Speed
- Scale
- Decision-making
- Personalisation
Automation
A device or system that accomplishes a function that was previously carried out by a human operator
4 stage model of information processing
- Acquisition Automation
- Analysis Automation
- Decision Automation
- Action Automation
Human Performance Consequences
- Mental workload
- Situation Awareness
- Complacency (= Over-trust)
- Skill Degradation
Automation Reliability and Costs of Decision/Action Consequences
- Benefits of automation only hold if it reliable
- Assesing appropiate level of automation depends on Risk ( = cost of an error x probability of that error)
- Little risk = High-level automation
- Operator can have veto power –> Error trapping mechanism
Neuroergonomics
Application of neuroscience to ergonomics and addresses the biological substrates of ergonomic concerns, with emphasis on role of human nervous system
Error-related Negativity
Negative electric potential, that activates when there is a human error
- Feedback signal
- Error monitoring
- Correlates with slips, not mistakes
- Onset can be prior to response
Human error
Human error is often unintenional and undesirable and is a contributing factor in accidents and distasters
E.g. Three mile island accident
Types of errors
Slips: Actions carried out without conscious deliberation (Failure to execute a good plan)
Mistakes: Incorrect assessment of stimuli or failure to select appropriate response (Failure to select a good plan)
Post-error slowing
After error, correct respones are given significantly slower (Try to avoid another error)
Omission error
Failure to do something
Mode error
Action performed inappropiately (e.g. doing sth. right, but in the wrong situation or wrong time)
