Question 3

Keywords and terms?

Answer 3

* Interactive System
Any system designed to facilitate interaction between human and computers.

* Domain
Represent a specific area of expertise of activity in the real world.

* Concepts
Represent the building blocks of the domain and include objects, actions, attributes, and relationships.

* Tasks
Actions or operations that users performs within a domain to achieve specific goals.

* Goals
The desired outcomes or results that users aim to achieve through performing tasks within the domain.

* Intentions
Specific actions or strategies that users employ to accomplish tasks and achieve goals.

* Task Analysis
A systematic process of identifying, describing, and understanding the tasks that users perform within a domain.

* System
The computational component of an interactive system, including..
hardware, software, and algorithms that enable the system perform tasks and interact with users.

* User
The human component of the interactive system

* Core language
Representation of the computational attributes of the domain that are relevant to the system state.

* Task language
Representation of the psychological attributes of the domain that are relevant to the user state.

Question 4

Two major phases of Norman’s model interactive cycle?

Answer 4

1. Execution phase
   Users engage with computer systems to perform tasks and achieve goals within a specific domain.
2. Evaluation phase
   Users assess the outcomes of their interactions with the system and make adjustments as needed.

Question 5

Execution phase steps?

Answer 5

1. Goal identification
2. Task Execution
3. System Response

Goal Identification
Users identify their objectives or goals within the domain.

Task Execution
Interacting with the system by..
providing inputs,
manipulating objects,
navigating interfaces,
and performing operations.

System Response
System responds by processing the input provided,
executing the required operations,
and generating feedback or output.

Question 6

Evaluation phase steps?

Answer 6

1. Feedback Reception
2. Feedback Evaluation
3. Adjustment and Adaptation
4. Goal Achievement or Revision

Feedback Reception
Users receive feedback from the system based on their actions and interactions.

Feedback Evaluation
Users evaluate the feedback received from the system to assess whether it aligns with their expectations and intentions.

Adjustment and Adaptation
Based on the evaluation of feedback, users may..
adjust their actions,
revise their goals,
modify their approach to better achieve their objectives.

Goal Achievement or Revision

Question 7

Interactive cycle divide further more?

Answer 7

1. Forming the goal
2. Forming the intention
3. Specifying the action
4. Executing the action
5. Perceiving the system’s state
6. Interpreting the system’s state
7. Evaluating the outcome

Question 8

Components of interaction framework?

Answer 8

I : Input
S : Core
O : Output
U : Task

Question 9

What is Ergonomics?

Answer 9

A multidisciplinary field focused on..
Designing and arranging environments, products, and systems to optimize human well-being and performance.
