User Interface Evaluation Methods

A design process that focuses on the needs of users throughout software development. It aims to create a connection with the intended user by understanding their needs and designing solutions that satisfy those needs.

The final stage of software development where the developed product is evaluated to assess its effectiveness and identify areas for improvement.

The ease with which users can understand, learn, and use a user interface. It measures how well the interface allows users to achieve their goals.

A method of usability evaluation that involves measuring user performance on specific tasks. It focuses on quantifiable data like completion time, error rate, and task success.

A method of usability evaluation that gathers subjective insights and opinions from users. It is used to understand user perceptions, feelings, and experiences with the UI.

The overall experience a user has with a product, software, or application. It encompasses all aspects of the interaction and includes feelings, satisfaction, and perception.

The timing of a user interface evaluation. It can happen early, in the middle, or after the development process.

The type and number of individuals involved in evaluating the user interface. It can involve HCI experts, domain users, or a combination.

The setting or environment in which the user interface evaluation takes place. It can be a controlled lab or a real-world scenario.

The location where the user interface evaluation is conducted. It can be in a laboratory or a real-world environment, such as the users' actual workplace.

A direct and simple interview method with users to understand their interaction behavior. It involves asking questions and observing their responses.

A process-oriented evaluation method where evaluators walk through a UI step-by-step to assess how easily users can learn and explore the system.

An evaluation method where HCI experts assess a user interface against established principles and guidelines. It uses known design principles to evaluate a UI.

An evaluation method that uses quantitative or qualitative metrics to measure the effectiveness of the interaction and interface design.

A type of usability evaluation that relies on numerical data, such as task completion time, error rate, and scores. It measures user performance on specific tasks.

A type of usability evaluation that uses subjective data, such as user feedback, to evaluate the UI's effectiveness. It involves gathering opinions, perceptions, and experiences from users.

It refers to the ability of a user interface to prevent errors and guide users towards successful task completion. It ensures that the system is designed to minimize mistakes.

It refers to the consistency and uniformity of design elements and functionality across the entire user interface.

It refers to the ease with which users can understand the current state of the system and know what is happening.

Refers to the layout and arrangement of elements on the screen. It should be clear, organized, and easily understandable for users to find information.

It refers to the design that considers the physical comfort and ease of use for users. It ensures that the interface is designed for comfort and accessibility.

It refers to the provision of help and support to users within the interface. Users should have quick and easy access to help when they need it.

The ability of a user interface to clearly communicate the system's current state and user actions. Users should always be aware of what's happening within the system.

A method that uses a small set of representative users to test and collect feedback on a user interface. It is a cost-effective way to get early feedback before releasing a product.

A type of usability testing where users are observed as they interact with a user interface. The goal is to identify problems and usability issues through observation.

It involves evaluating a user interface based on the principles of user-centered design and usability. It aims to identify any violations of these principles and suggest improvements.

It refers to the ease with which a user interface can be learned and used. It includes aspects such as learnability, memorability, and ease of operation.

The ability of a user interface to be remembered and easily relearned after a period of inactivity. Users should be able to easily recall how to use the system after some time.
