What technique provides an overview of how a user feels and experiences while using an application?

The technique that provides an overview of how a user feels and experiences while using an application is the Empathy Map. This tool helps teams visualize users' attitudes and behaviors by mapping out different aspects of their experiences, such as what they see, hear, say, and do, as well as their pain points and gains. By understanding these elements, teams can gain deeper insights into user motivations and emotions, which are critical for designing an application that meets users' needs and addresses their concerns effectively.

In contrast, Stakeholder Analysis focuses on identifying and understanding the interests and influence of various stakeholders involved in a project rather than the user's personal experience. Usability Testing is a method used to evaluate an application's performance by observing real users as they interact with it but does not provide a holistic emotional overview like the Empathy Map does. User Personas, while useful for representing target users based on research, do not capture the experiential and emotional aspects in the same way that an Empathy Map does. Thus, using an Empathy Map enables teams to build a more user-centered application by placing a strong emphasis on the user's feelings and experiences.
