Progress

But as our processes progressed - and our Our
technology progressed - Our ability to keep
operators informed of what was happening and
what to do about it became more difficult.

Several Major Incidents Move Human Factors to
the Forefront
One of the first insights from the TMI incident
in 1979 was that errors resulting from human
factors deficiencies in the control room were a
significant contributing factor in incidents
and accidents and not enough effort was put
into understanding the Human Machine Interface
10
What is Human Machine Interface?

• Called a variety of names
• Human Factors (HF)
• Ergonomics
• Man-Machine Interface (MMI)
• Human-Computer Interface (HCI)
• Human factors engineering is the science and art
  of designing the environment, tools, and tasks so
  they interact well with humans as part of a
  system.
• Much of it applies to ergonomics and
  anthropometrics
• HMI focuses primarily on the Human-Computer
  Interface.
• It is where people and technology meet.

11
Human Machine Interface
Prior to VDU (CRT) displays, Efforts were made to
enhance ergonomics by

• Color Coding
• Placement
• Tactile Controls
• Graphics
• Audio/Visual Cues
• Labeling
• Etc

Were Not In Kansas Anymore!
Our Process Systems Are Not Simple Our
Technology Is Not Simple Our Control Systems Are
Not Simple Our Interface to the Process Is No
Longer Simple
We need a Standard or Guideline to follow!

ISA Control Center Standards
Among other ISA Standards, ISA Published
RP60.3 in 1985 Human Engineering of Control
Centers Design concepts accommodating mans
physiological and psychological capabilities
Although much of the material still applies, it
is still directed At indicators, switches,
annunciators, etc. (i.e. Hardware)
