Gerhardt-Powals’ cognitive engineering principles Flashcards
Automate unwanted workload:
free cognitive resources for high-level tasks.
eliminate mental calculations, estimations, comparisons, and unnecessary thinking.
Reduce uncertainty:
display data in a manner that is clear and obvious.
Fuse data:
reduce cognitive load by bringing together lower level data into a higher-level summation.
Present new information with meaningful aids to interpretation:
use a familiar framework, making it easier to absorb.
use everyday terms, metaphors, etc.
Use names that are conceptually related to function:
Context-dependent.
Attempt to improve recall and recognition.
Group data in consistently meaningful ways to decrease search time.
Limit data-driven tasks:
Reduce the time spent assimilating raw data.
Make appropriate use of color and graphics.
Include in the displays only that information needed by the user at a given time.
.
Provide multiple coding of data when appropriate.
.
Practice judicious redundancy.
