Users should be involved only at the final testing stage.

User involvement can improve usability but also take more time.

User-centered design ignores the context of use.

Iterative design means redesigning and testing multiple times.

Empirical measurement involves collecting real user data during testing.

The Double Diamond model discourages exploration before defining the problem.

User-centered design focuses only on the appearance of products.

Users’ opinions can sometimes conflict during involvement.

Successful interaction design ensures both usability and user satisfaction.

Cognition includes memory, attention, and problem-solving.

Perception is unrelated to interface colors.

Users form mental models to predict system behavior.

Working memory is unlimited.

Feedback must be immediate in good interfaces.

Affordance explains how users feel about the UI.

Activity theory focuses on real user behavior patterns.

Hick’s Law states that more choices increase decision time.

Cognitive load increases when UI is cluttered.

Fitts’s Law applies to pointing tasks like mouse clicking.

Gestalt laws describe human visual grouping.

Signifiers are unnecessary in interactive design.

Long-term memory is better for storing detailed instructions.

Attention is a limited cognitive resource.

Users always remember system steps after first use.

Perception can be influenced by color, shape, and motion.

Activity-centered design ignores tasks.

External cognition reduces memory burden.

Bad UI mapping increases user errors.

Sound feedback is a form of system perception.

Instructing interaction supports quick and efficient interaction.

Recognition requires more mental effort than recall.

Conversational interfaces may be speech-based or text-based.

Conversational interaction is unsuitable for novice users.

Manipulating interaction exploits knowledge of the physical world.

Direct Manipulation uses complex command syntax.

Immediate feedback is a key feature of DM interfaces.

DM interfaces are difficult for novice users to learn.

Some tasks are better delegated than directly manipulated.

Exploring interaction includes browsing websites.

Hybrid conceptual models support multiple ways of interaction.

Interaction type and interface type mean the same thing.

Speech and gesture are interface types.

Budget constraints affect interaction type selection.

All tasks can be represented using direct manipulation.

Interaction design focuses only on how an Android app looks.

User-Centered Design starts by understanding user goals and context.

Material Design is the official design system recommended for Android apps.

Instructing interaction involves gestures such as pinch-to-zoom.

Manipulating interaction allows users to directly control on-screen objects.

Conversational interaction in Android can be implemented using chatbots or voice input.

Exploring interaction is commonly used in navigation and browsing interfaces.

Bottom navigation should be used for switching between primary sections of an app.

Providing feedback helps users understand system status and results of actions.

Consistency in icons and terminology increases the learning difficulty of an app.

Accessibility features are only required for users with disabilities.

Large touch targets improve usability on mobile devices.

Error prevention can be achieved by confirming destructive actions.

Slow response time negatively affects user experience in Android apps.

Prototyping and usability testing should be done after final deployment only.
