This thesis explores the impact of emotion-focused design on the user experience of a website. That is, when creating a website if attention is focused on the user's emotions and the emotions which want to be awakened, how does this influence the quality of the user experience. An emotion-focused design is one that evokes appropriate emotions to create a positive user experience and encourage the user to behave in the desired way. The theoretical part of the paper explains what emotions are and why it is important to pay attention to emotions when designing a website. The principles and strategies of emotion-oriented design and how certain design elements affect user emotions are presented. For example, cool blue is the least exciting color and associated with the most comfortable and cozy feelings. The experimental part of the paper is based on the redesign of an existing website of the Croatian Peace Association - HUM, development of a prototype according to the principles of emotion-oriented design. To analyze the impact of emotion-focused design on the user experience, the association’s current website was compared to a prototype. The research was conducted through moderated interviews and surveys. The results of the interview showed that emotion-focused design influences the user experience on the website. Users experienced the prototype much more positively and were able to complete tasks faster. It has been confirmed that an emotion-focused design instills more confidence compared to the design of the current website.
