Interface sob análise: uma avaliação da experiência do usuário em aplicativo de registro de ponto eletrônico

Abstract

This study aimed to evaluate the usability and accessibility of a time-tracking application used by employees to record their work hours electronically. The adopted methodology combined a heuristic evaluation, usability testing with real users, and an automated accessibility analysis. Metrics such as success rate, error rate, average completion time, and the ASQ and SUS questionnaires were used to ensure a comprehensive assessment. The results revealed 23 usability violations, highlighting issues related to system consistency and visibility. The average SUS score was 67.5, indicating an acceptable level of usability but with room for improvement, particularly in the timesheet signing feature. The accessibility evaluation identified barriers such as low contrast and small touch targets. The proposed recommendations aim to foster a more inclusive experience, aligned with Human-Computer Interaction (HCI) principles and user experience (UX) best practices. For future work, it is recommended to expand accessibility testing with users with disabilities and consider developing a new user-centered solution.
