The importance of buttons in UI design and their impact on mobile app usability: case study

Abstract

Buttons in mobile applications are often overlooked elements of user interface (UI) design, yet they play a critical role in guiding user interactions and ensuring a seamless user experience (UX). This research focuses on the Uber ride-sharing app, highlighting the challenges and implications of button design on its usability. Despite their simple appearance, buttons are vital for effective navigation, and poor design can lead to user confusion, frustration, and even task abandonment. This study identifies specific issues with the Uber app’s current button design, particularly the “cancel ride” button, which is difficult to locate and often perceived as disabled by users. By conducting usability tests and proposing a redesign focused on improving button visibility, colour contrast, and hierarchical structure, the study aims to enhance the app’s usability. The results suggest that thoughtful button design can significantly improve user satisfaction and reduce errors, especially in critical tasks like ride cancellation. The suggested changes include adding distinct visual cues for secondary and destructive buttons to enhance user experience. Future work will involve conducting usability tests to validate these design improvements and ensure they effectively address the identified issues
