Cognitive, Communication, & Collaboration Models Flashcards
This is rooted in cognitive science as well as in ergonomics and human factors enginering.
Traditional HCI
What are the Cognitive Models?
- Goal and task hierarchies
- Linguistic
- Physical and Device
- Architectural
What are the model aspect of a user?
- Understanding
- Knowledge
- Intentions
- Processing
What are the common categorization?
- Competence vs. Performance
- Computational Flavor
- No clear divide
What are the Three advantages that keeps the task simulation distinct from the cognitive model?
- It makes development easier, because the model and the simulation can be tested and debugged independently.
- It makes it less likely that the modeler will unintentionally incorporate assumptions about the task into the cognitive model, or about cognition into the task simulation
- It makes it easier to use different cognitive models with the same task simulation, or to apply the same cognitive model to different tasks.
This is an idea of the future or desired result that a person or a group of people envisions, plans, and commits to achieve.
Goal
This can contain a specific workload or assign in a particular scenario we’re in result came out.
Task
These goals are internal.
GOMS
These actions are external; tasks; are abstractions.
HTA
What is the meaning of GOMS?
Goals, Operators, Methods, Selections
What is the meaning of HTA?
Hierarchical Task Analysis
This is what the user wants to achieve
Goals
This is the basic actions user performs
Operators
This is the decomposition of a goal into sub goals/operators
Methods
This means of choosing between competing methods
Selection
