HLTH 173 – Week Nine Notes
What is automation?
-Automation – Characterizes the circumstances when a machine assumes a
task that is otherwise performed by the human operator
What are the 4 main reasons to automate?
1. Carry-out impossible or hazardous tasks – Ex. Robotic handling of
hazardous material; Serving needs of special populations who can not
perform certain tasks (disabilities) – Ex. Automatic guidance systems for the
quadriplegic or Automatic readers for the visually impaired
2. Carry-out difficult or unpleasant tasks – Ex. Calculators (Math can easily be
done in your head, but its more effortful and has more potential for error)
3. Extend human capability – Some technology aids instead of replaces (Ex.
How pilots say auto-pilot mode is helpful when other tasks are weighing on
them and they cannot do everything at one)
4. Technically possible – Some functions are automated simply because the
technology is there (Ex. How certain companies keep putting out “new and
improved” models when there really is not much of a usability difference –
purported “technological sophistication” can be misleading to public)
What are the 4 main levels of automation?
1. Information Acquisition, Selection, and Filtering - Alarms, Red squiggly in
Word (All about Selective Attention!)
2. Information Integration - Perception and memory (Taking pieces of
information and putting them together; Ex. Geographic map of hurricane
course from satellite data; Other Ex. Any graph or chart, a Google search
showing you relevant info as opposed to everything on the Internet)
3. Action and Selection Choice – Ex. Collision awareness system for pilots
4. Control and Action Execution - Ex. Google car, Amazon delivery drones
(Amazon Prime Air)
What are the 3 main factors of reliability & trust?
1. Unreliable, or Unreliable in certain situations
2. Incorrectly setup
3. Unsuspected reactions
What does overtrust and complacency entail?
-Mistrust – Occurs when trust is not directly related to reliability; Can either
be distrusting or overtrusting
-Ex. Google Cars:
oConsequences of Distrust: Goes unused
oConsequences of Overtrust: Detection, Situation awareness, Skill loss
-A lot of times issue isn’t technology itself; It is the relationship between
users and technology*
