In this work, we prepared three variations of a prototype to experimentally manipulate parameters helping to improve User Experience (UX) of technological products. Based on a model considering the fulfilment of user needs (Fig. 1), two variations of a neutrally designed tool were developed to address two selected needs (popularity, competition) by slightly changing functionalities or design elements. The manipulation of UX is validated with real-time and retrospective subjective evaluation of UX, and objective data of user behaviour. Participants rated significantly higher positive UX and showed more active behaviour for designs of the prototype addressing the user needs competition and popularity compared to the neutral design. These findings show the importance of considering elements of UX in the early development process of technological products.
