UX Glossary

Editorial guidelines are a set of rules and standards that govern the creation, quality, and consistency of content in a specific context.

Effective, in user experience, refers to a user's ability to achieve their goals accurately and completely. It is one of the three key components of usability, alongside satisfaction and efficiency.

Efficiency in UX refers to the ability to achieve desired outcomes with minimal effort and resources. It is often applied in multivariate testing, where multiple design elements are tested simultaneously to optimize performance and user experience.

Efficient refers to a user’s ability to complete tasks with minimal effort and cognitive load. It is one of the three key components of usability, alongside satisfaction and effectiveness, and is essential in evaluating user experience design.

Electroencephalography (EEG) is a method for recording electrical activity of the brain via sensors placed on the scalp. In UX, it is used to study users' emotional responses and cognitive states during interactions with products.

Emotion Recognition is the ability to identify and interpret human emotions through various cues such as facial expressions, voice tone, and body language.

Emotional attraction measures the degree of positive or negative feelings a user experiences toward a product or interface. It is often assessed using EEG to understand user engagement and emotional response during interactions.

Emotional Design is the practice of creating products that evoke specific emotions through visual elements and functionality. It is used in UX to enhance user engagement and satisfaction by aligning design with users' feelings and experiences.

Emotional engagement refers to the level of visceral response users experience during an interaction. It is often assessed through techniques like EEG to understand user feelings and improve design effectiveness in UX and product development.

Empathic Design is a user-centered design approach that prioritizes understanding users' emotions, needs, and experiences to create more meaningful products.

Empathy is the ability to understand and share the feelings of users. In UX design, it involves gaining insights into users' needs and challenges to create solutions that effectively address their experiences and emotions.

An empathy map is a visual tool used by designers to capture and summarize user insights. It includes four quadrants—“Says,” “Thinks,” “Does,” and “Feels”—to help understand user perspectives and enhance empathy in the design process.

Empirical validation is the process of confirming design decisions by analyzing real user data, such as interactions and feedback. It is used in UX to ensure designs meet user needs and improve usability during the design and testing phases.

Empty Placeholder Text is temporary text displayed in input fields that vanishes when the field is focused. While it helps indicate what to enter, it can create accessibility issues by providing insufficient context for screen reader users.

An Empty State is a UI screen displayed when there is no data or user activity present. It serves to guide users during onboarding and provides context or prompts for potential actions to take.

Empty State Design involves creating user experiences for scenarios where no content is available to display. It is used to guide users, provide context, and encourage actions when an application or feature is empty.

End-User Experience (EUX) is the overall perception and emotional response of a user when interacting with a product, service, or system. It is evaluated through usability, accessibility, and satisfaction, influencing user engagement and long-term loyalty

The Endowment Effect is a cognitive bias where users value items more highly simply because they own them. This bias can impact product design and user experience by influencing purchasing decisions and perceived value of features.

Engagement refers to the interaction and involvement of users with a product, service, or content, measuring their interest and commitment.

Engagement metrics are quantitative measures that indicate how users interact with a product or service, reflecting user involvement and satisfaction.

Engagement Rate measures the level of interaction users have with a product or service, often expressed as a percentage of total users or interactions.

Engagement time measures the duration a user spends on a web page. It is used in UX and product work to assess user interest and interaction, helping to inform design decisions and improve user experience.

Engaging refers to the degree of emotional connection a user feels with a product or experience. It is a key factor in user experience design, influencing user satisfaction, retention, and overall interaction with the product.

An Epic is a sizable body of work that can be broken down into smaller tasks or user stories, usually spanning multiple sprints in Agile methodologies.
