Lesson 1- Models and Theories Flashcards
a crucial role in Human-Computer Interaction. They help designers and researchers understand how users perceive, learn, and interact with computer systems.
Cognitive Models
Cognitive Models (4) GOMS
- Goals
- Operators
- Methods
- Selection
refer to the desired outcomes that users aim to achieve when interacting with a computer system or software.
Goals
the low-level actions or operations that users execute to achieve specific goals or tasks within a computer system.
Operators
represent a higher level of abstraction than operators and describe the sequence of operators employed to achieve a goal.
Methods
consider factors such as the visibility and accessibility of options, the layout of the interface, and the cognitive processes involved in decision-making.
Selection
is to understand how users perform specific activities and to identify the steps and interactions involved in completing a task.
Task Analysis
Approaches of Task Analysis(5):
- Hierarchical Task Analysis
- Cognitive Task Analysis
- Ethnographic Observation
- Scenario-Based Design
- . Job Task Analysis
Methods of Task Analysis (5):
- Observation
- Interviews
- Surveys and Questionnaires
- Think-Aloud Protocols
- Job Shadowing
Represents a computer system’s internal workings, with a focus on the interactive aspects and how it responds to user interaction.
Helps designers understand the system’s behavior and ensures that it is consistent, predictable, and simple to learn.
Model of the System
Types of System Models (3):
- Dialogue
- Full-State
- Abstract
is the construction of interaction between two or more beings or systems.
Dialogue
describes the timely behaviour of the class objects over a period of time
Full-State
refers to the intentional simplification of a system’s representation to focus on its essential features and behaviors, while omitting unnecessary details.
Abstract
Dialogue Design (3):
- Lexical
- Syntactic
- Semantic
Shape of icons, actual keys pressed, etc., are dealt at this level.
Lexical
The order of inputs and outputs in an interaction are described at this level.
Synctactic
At this level, the effect of dialog on the internal application/data is taken care of.
Semantic
are a common visual modeling technique used in software engineering to illustrate the behavior of complicated systems.
State Diagram
State Diagram is also known as ____ ?
State Machine Diagram
is a term for application written to support the collaboration of several users.
Groupware
Types of Groupware: Synchronous and Asynchronous
Two groups related to place (2)
(what? Baka hndi na naman to kasama. Ignore it muna)
- Collocated
- Non-Collocated
is any form of communication between two or more individuals mediated by interconnected computers.
Computer-Mediated Communication (CMC)
