felhasználhatóság

Felhasználhatóság, or usability in English, refers to the extent to which a product, system, or service can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use. It is a critical aspect of user experience design and human-computer interaction.

The concept of felhasználhatóság encompasses several key components. Effectiveness measures how accurately and completely users can achieve their goals. Efficiency evaluates the resources expended in relation to the accuracy and completeness with which users achieve their goals. Satisfaction assesses the comfort and pleasantness of use. These components are often measured through usability testing, where users interact with a product while observers note problems and collect quantitative data.

Good felhasználhatóság is achieved through user-centered design processes, which involve understanding user needs, designing with those needs in mind, and iterating based on user feedback. This approach ensures that the final product is intuitive, easy to learn, and efficient to use. Common methods to improve usability include user research, personas, usability testing, and iterative design.

In the context of digital products, such as websites and software applications, usability is often guided by principles like consistency, clarity, and feedback. Consistent design elements help users understand how to interact with the system, while clear instructions and feedback reduce user errors and enhance the overall experience.

Felhasználhatóság is not limited to digital products; it applies to any user-facing system or service. In physical products, for example, usability might involve ergonomic design and intuitive controls. Regardless of the context, the goal of usability is to create products that are accessible, efficient, and enjoyable to use.
