GOMS Model Flashcards
(26 cards)
What is the GOMS model?
a cognitive modeling method for task analysis
What does the GOMS model provide?
“How to do it” knowledge that a user must have in order to carry out tasks on a device or system
In the GOMS model, each user task is described by a ________ and a ________.
goal
method
What is a method?
a sequence of steps, each consisting of one or more operators
In the event that a user task has more than one method, a ________ will be needed.
selection rule
How does GOMS differ from the Human Processor model?
The GOMS model is task-specific and focuses on user interaction with computer systems, while the Human Processor Model is a general model of human cognitive architecture
The ________ model is more practical and applied, especially in user interface design and usability testing, while the ________ model is more theoretical and used for understanding basic cognitive processes.
GOMS
HPM (human processor model)
GOMS provides a detailed method for analyzing ________, whereas HPM offers high-level view of ________.
specific user tasks
cognitive processing
Define goals
objectives that a user wants to achieve
These represent the desired end state that the user is working toward.
Goals
Define operators
elementary steps that users take to achieve goals
(T/F). Operators are physicalactions.
False
They can be physical, such as clicking a mouse;
or mental, such as recalling a command from memory.
A ________ is essentially a way of doing something.
method
Define selection rules
guidelines that users follow to choose between different methods to achieve a goal
________ are the basic actions the user can perform.
Operators
________ help the user decide among multiple methods.
Selection rules
In HCI, ________ is primarily used for cognitive analysis.
GOMS
In HCI, ________ helps in understanding the user’s thought process and actions when interacting with a system.
GOMS
GOMS aids in UI design by predicting and quantifying ________, which can lead to more efficient, user friendly interfaces.
user performance
GOMS can be used to evaluate the usability of a system by identifying and quantifying the ________ and ________ required to perform tasks.
cognitive load
effort
GOMS provides a structured approach to analyzing ________.
user interaction
GOMS helps in predicting how changes to a user interface will affect ________.
user performance
GOMS is useful in identifying and eliminating ________ in a user interface.
unnecessary or redundant steps
A limitation of GOMS, is that it tends to focus more on…
expert users who are well acquainted with the system.
