Interaction Design Lecture 3

Instructing involves giving commands and making selections, like interacting with a menu or a command line interface.

Conversing involves having a dialogue-like interaction with a system, like using a chatbot or a voice assistant.

Manipulating involves directly interacting with virtual or physical objects, like moving items in a 3D game or using a touch screen.

Exploring involves navigating through a virtual or physical space, like moving through a website or exploring a city using a map.

The study of how emotions influence and are influenced by interactions with technology. It's about understanding how people feel while using computers and how their feelings affect their actions.

Basic emotion refers to fundamental, universal human feelings like joy, sadness, anger, fear, and disgust. They are innate and play a significant role in human behavior.

Data gathering is the process of collecting information to understand user needs and requirements for designing a system. This information is crucial for making informed decisions about the design.

Setting goals in data gathering involves clearly defining what information needs to be collected and how it will be used to improve the design. This helps ensure the research is focused and effective.

A way to collect data by observing behaviors, events, or physical characteristics in their natural setting.

Direct observation involves observing the target directly, either passively or actively.

Indirect observation involves collecting data from sources not directly observed, like diaries or analytics.

A researcher observes without influencing what is being observed, often in a natural setting.

A researcher actively participates in or intervenes in the situation being observed, often in a controlled environment.

A method where participants describe their thoughts aloud while performing a task. This is usually in a controlled setting.

A type of indirect observation where researchers collect data from written records kept by individuals.

A type of indirect observation where data is gathered from recorded interactions between people and a system.

A type of indirect observation where website activity data is collected and analyzed.

Using multiple sources of data, methods, or perspectives to gain a more comprehensive understanding of a research topic.

A preliminary test of a research method before conducting a larger study.

An interview with no predetermined questions, allowing participants to freely express their thoughts.

A structured interview uses pre-set questions asked in the same order to all participants, often with standardized scoring.

Interviews conducted with a group of participants to gather diverse perspectives and insights.

Survey methods that ask pre-determined questions to a large number of participants using a standardized format.

Ensuring that the participants chosen for a survey are a representative sample of the broader population.

The percentage of survey recipients who actually complete and return the questionnaire.

Clear instructions explaining how to fill out the questionnaire, including whether multiple answers are allowed.

Asking basic information about participants, like gender, age, and place of birth.

Collecting details about participants' relevant experience in the study's subject area, like computer usage or expertise.

A way to organize the structure of a system by grouping related elements in a hierarchical fashion, often used for menus and interfaces.

Shows connections between pages that might not be grouped together in a hierarchical organization, focusing on tasks and relationships.

Physical grouping of elements that logically belong together, enhancing visual clarity and user understanding.

The use of empty space to enhance visual organization and readability, allowing for easier distinction between elements.

Rules that guide the design process, ensuring the resulting software is usable and effective. Each rule can be classified as a standard, guideline, or principle.

Investigator triangulation involves having multiple researchers working on a project. This helps ensure that different perspectives and interpretations are considered, leading to more reliable and accurate results. It's like having several chefs taste a dish—each brings a unique palate and experience, resulting in a more balanced flavor.

Methodological triangulation refers to using a variety of research methods to study the same phenomenon. This allows researchers to explore the phenomenon from different angles, providing a more comprehensive understanding of the subject. Imagine examining a car from different angles—front, back, and sides—to get a better picture of its overall shape.

Theoretical triangulation involves using multiple theories to analyze research data. By considering different perspectives and explanations, researchers can gain a deeper understanding of the phenomenon under investigation. It's like looking at a painting through different lenses—each lens reveals a unique aspect of the artwork.

Design is about achieving goals within certain limitations. These limitations can include factors like available materials, platforms, or budget constraints. It involves making trade-offs to meet the most important goals while acknowledging these constraints. Like building a house, you need to consider the available materials and budget to realize your vision of a dream home.

Navigation design in HCI focuses on how users move within an interface and locate their position. Navigation controls like menus and links are vital for guiding users through the interface. It's like navigating a city with street signs and maps—they help you find your way around and understand where you are.

Local structure in navigation design refers to the arrangement of elements within a single screen or page. It aims to create a cohesive and intuitive layout for the user. Imagine a website page with clearly organized sections and headings—this is an example of a good local structure.

Global structure in navigation design refers to how all the screens within an interface are interconnected. It ensures a logical flow and allows users to navigate seamlessly between different parts of the interface. Think of a website with a menu bar that links to different sections—this represents the global structure.
