Aplicação de microinterações no portal institucional da UTFPR para melhorar a experiência do usuário

Abstract

Institutional university portals must provide clear communication and efficient navigation to en sure that students, staff, and visitors can access information quickly and intuitively. In this context, usability and user experience play a crucial role in the quality of digital services offered by academic institutions. This Graduation Completion Work investigates the strategic application of microinteractions as an important factor for optimizing the User Experience (UX) on the Institutional Portal of the Federal Technological University of Paraná (UTFPR). The current scenario demands that information access interfaces present high communicability and navigation efficiency, especially for the academic community. The primary goal of this research was to diagnose existing communication failures and propose a verifiable design solution. The methodology employed combined qualitative analysis, conducted through the Semiotic Inspection Method (MIS) with the participation of five specialists, and subsequent quantitative validation via A/B Testing. The application of MIS across five interaction scenarios revealed critical Communication Ruptures (RCs), which predominantly concentrated on dynamic and metalinguistic signs. A systematic lack of immediate dynamic feedback (such as the absence of hover states or loading indicators) was identified, leading to user uncertainty regarding action effectiveness and compromising interaction fluidity. Simultaneously, a consistent failure in metacommunication was observed, manifesting as a lack of tooltips and contextual explanations for ambiguous or non-standard elements, like accessibility features. In response to this diagnosis, a Design Strategy focused on implementing specific microinteractions, such such as subtle haptic feedback on buttons and visual loading signals (skeletons), was developed. The resulting high-fidelity prototype, built in Figma Pro, serves asthe basis for the A/B Tests, aiming to measure the direct impact of the microinteractions on user efficiency and satisfaction metrics. It is concluded that the proposed intervention can contribute to raising to elevate the Portal’s usability, providing concrete guidelines for the continuous improvement of the institution’s digital experience.
