Which designer type focuses on functional aspects and how a product operates?

The focus of interaction designers is primarily on the functional aspects of a product and how users interact with it. This role emphasizes creating intuitive and efficient user experiences by considering how users will engage with a product's interface and features. Interaction designers study user flows, task analysis, and usability to ensure that the product is not only visually appealing but also easy to use and effective in its function.

By concentrating on how the product operates, interaction designers ensure that all elements of the interface work seamlessly together, enhancing the user's ability to achieve their goals without confusion or frustration. This design discipline involves a deep understanding of user needs and behavior, which allows interaction designers to create solutions that provide a satisfying user experience. The role also often involves prototyping and usability testing to refine the interactions before final implementation, ensuring the product is user-friendly.
