A Critical Evaluation of Popular UX Frameworks Relevant to E-Health Apps

Abstract

This research paper aims to evaluate the usability, accessibility, and effectiveness of the current User Experience (UX) frameworks relevant to mobile health apps, with a specific focus on the FitBit app. The selected UX frameworks for evaluation include Nielsen Norman Group's 10 Usability Heuristics, Don Norman's Three Levels of Design, and Human-Centered Design. A mixed-method approach, comprising both qualitative and quantitative analyses, was employed to evaluate these frameworks. The FitBit app was assessed based on the selected frameworks, and the obtained results were compared with existing literature and industry standards. The main subject of this study is the critical evaluation of popular UX frameworks in the context of e-health apps, with a specific emphasis on the FitBit app. The evaluation factors considered include usability, accessibility, and effectiveness. By utilizing the selected UX frameworks, the paper seeks to identify the strengths and limitations of each framework in evaluating e- health apps. The achieved results reveal that Nielsen Norman Group's 10 Usability Heuristics are valuable in identifying usability issues within the FitBit app. Don Norman's Three Levels of Design effectively evaluate the overall user experience, providing insights into the app's design quality. Human- Centered Design, on the other hand, offers a comprehensive and holistic approach to designing for the user, encompassing various aspects of the FitBit app. Through this research, a comprehensive understanding of the strengths and limitations of the evaluated UX frameworks in relation to e-health apps, specifically the FitBit app, is attained. The findings contribute to the existing literature on UX evaluation and provide insights for designers and developers to enhance the user experience of mobile health applications.
