Question 5 – Interaction Types

Correct Answer

✅ (b), (c), (d)

High-Level Theory

Interaction Design includes different ways users communicate with systems:

• 1. Instructing: Giving commands (Click "Print", Press Save).
• 2. Conversing: Talking with the system (Siri, ChatGPT, Alexa).
• 3. Manipulating: Directly moving objects (Dragging files, Zooming photos).
• 4. Exploring: Moving through physical or virtual spaces (Google Maps, VR games).

Option Explanation

❌ (a) Instructing means direct manipulation (Instructing is giving commands, not manipulating objects)

✅ (b) Conversing = dialogue

✅ (c) Manipulating = dragging and gestures

✅ (d) Exploring = moving through environments

❌ (e) Responding means giving commands (Responding refers to the system reacting to user input)

💡 Exam Tip: Instructing → Commands | Conversing → Talking | Manipulating → Drag & Touch | Exploring → Navigation

Question 6 – Multimodal Interfaces

Question

Which of the following statements are true about multimodal interfaces in user experience design?

Correct Answer

✅ (b), (d)

High-Level Theory

A Multimodal Interface allows users to interact with a computer using more than one input or output method (e.g., touch, voice, gestures, screen, sound). Examples include smartphones and smart TVs.

Option Explanation

❌ (a) They allow users to interact using a single consistent input like keyboard only.
This describes a single-modal interface.

Everyone can use multimodal interfaces.

✅ (d) They enhance expressiveness and flexibility in HCI.
Users can choose the interaction method they prefer.

❌ (e) They replace all GUI interfaces.
GUI is still widely used; multimodal interfaces usually work together with GUI.

💡 Exam Tip: Multi = Many, Modal = Mode. Multimodal = Many ways to interact (Input: Touch, Voice, Gesture | Output: Screen, Sound, Vibration).

Question 7 – Experiential Cognition

Question

Which of the following are characteristics of Experiential Cognition?

Correct Answer

✅ (b), (c)

High-Level Theory

Experiential Cognition refers to thinking that happens automatically while performing familiar, routine activities (like driving or typing). It develops through practice and requires little conscious thought, unlike Reflective Cognition which involves deep thinking and problem-solving.

Option Explanation

❌ (a) Deliberate thinking and judgement
This is Reflective Cognition.

✅ (b) Happens automatically during routine activities
Core definition of Experiential Cognition.

✅ (c) Driving, reading and watching videos
These activities become automatic through experience.

This is also Reflective Cognition.

💡 Exam Tip: Experiential = Automatic & Routine | Reflective = Deep Thinking & Problem Solving.

Question 8 – Mental Models

Question

Which statements are true regarding Mental Models in Interaction Design?

Correct Answer

✅ (b), (c), (e)

High-Level Theory

A Mental Model is the user's understanding or expectation of how a system works, developed through experience and observation. Designers should create Conceptual Models that match users' Mental Models to improve usability. Incorrect mental models lead to user errors.

Option Explanation

❌ (a) Mental models are always technically correct.
Users can misunderstand systems.

✅ (b) Users quickly form mental models.
People begin making assumptions immediately.

✅ (c) Designers should match conceptual models with users' mental models.
This improves usability.

❌ (d) Mental models never change.
They improve and change as users gain experience.

✅ (e) Incorrect mental models cause misunderstanding.

💡 Exam Tip: Mental Model = User's understanding | Conceptual Model = Designer's plan. Good design aligns both!

Question 9 – Distributed Cognition

Question

Which statements reflect the Distributed Cognition framework?

Correct Answer

✅ (b), (c), (e)

High-Level Theory

Distributed Cognition states that thinking is not just inside one person's brain; it is shared among people, computers, documents, tools, and the environment. Examples include airline cockpits (pilot + instruments) or using a shopping list/Google Maps to offload memory.

Option Explanation

❌ (a) Thinking only happens inside one person's mind.
Opposite of Distributed Cognition.

✅ (b) Thinking is shared across people, tools and environment.
Main definition.

✅ (c) Documents become part of thinking.
