Human-Computer Interaction: UI Design and Usability

Vocabulary flashcards covering core human-computer interaction concepts, interface types, feedback modalities, Shneiderman's rules, usability standards (ISO 9241-11), and UI design principles from HCI101 quizzes.

A multidisciplinary field of study that focuses on designing, implementing, and evaluating user-friendly interfaces (UIs) for digital products.

Human-Computer Interaction

An interface used in applications where users need to input specific data into fields.

Form-Based Interface

An interface that relies on body movements and gestures.

Gesture-Based Interface

The set of design elements that maximize seamless interaction and create pleasurable user experiences.

Graphic User Interface Design

A text-based interface where users type commands to operate software or systems.

Command Line Interface

An interface that uses visual elements like windows, icons, and buttons, making it accessible and easy to use.

Graphical User Interface

An interface that allows users to interact through a list of options.

Menu-Driven Interface

An interface that allows users to interact with systems through voice commands, commonly used in smart home devices.

Voice User Interface

An interface that allows users to interact with machines using conversational language through voice or text, such as in customer service bots and virtual assistants.

Conversational Interface

An interface used with AI and machine learning that allows users to interact using everyday language.

Natural Language Interface

An interface used in smartphones and tablets that allows users to interact with devices using touch gestures.

Touchscreen Interface

An interface providing a fully immersive environment where users interact with a computer-generated world.

Virtual Reality Interface

One of the most common types of feedback used in UI design to convey system state visually.

Visual Feedback

A type of feedback that involves using sound to convey information to the user.

Auditory Feedback

A type of feedback that involves using tactile responses to convey information to the user.

Haptic Feedback

A rule in interface design that helps users transfer knowledge from one part of the system to another.

Interface Consistency

System responses provided right after an interaction that help users understand the results of their actions.

Immediate and Informative Feedback

A design practice based on Shneiderman's rules that is considered more effective than relying on error messages after the fact.

Error Prevention

A design principle allowing users to undo actions easily, which reduces anxiety and encourages exploration.

Reversal of Actions

A UI design principle ensuring that systems and buttons behave in a way users expect.

Principle of Least Astonishment

A UX principle stating that users expect your site to work like other familiar websites, cautioning against excessive creativity that breaks user expectations.

Jakob's Law of Internet User Experience

A UI design principle that helps users feel more confident and reduces frustration by enabling easy recovery and autonomy.

User Control and Freedom

A design goal aimed at presenting identifiable options to users, because recognition is faster and reduces cognitive load compared to recalling information from memory.

Recognition over Recall

The three key components of usability defined under ISO 9241-11: Effectiveness, Efficiency, and Satisfaction.

Components of Usability (ISO 9241-11)

The system's capacity to support a range of user actions and help users recover from errors.

Error Tolerance

An assessment conducted during the design process to determine how easy and enjoyable it is for users to achieve their goals.

Usability Evaluation

A component of user experience design that comes after utility and before desirability and brand experience.
