Human-Computer Interaction Design Principles for Enhancing User Experience in Mobile Applications

As mobile technology continues to evolve, so has the need for rich, immersive, and easy-to-use applications. The concepts of Human-Computer Interaction (HCI) are indispensable for User Experience (UX) because this field ideally troubleshoots accessibility, usability, and engagement problems. In this study, we propose a novel mobile app design model derived from state-of-the-art theories related to human-computer interaction (HCI), artificial intelligence (AI), and gesture-recognition and ability-based design to deliver intuitive, adaptive, and inclusive mobile applications.This research also improves accessibility, allowing adaptive and customizable experiences by integrating IoT data with user profiles. The article highlights the importance of built-in accessibility frameworks in mobile apps, which will be of exceptional help to users with disabilities in participating effectively in the digital realm. Another focal point is gesture-based interactions, where the optimization of gestures makes mobile interfaces more natural. However, non-standard hardware and UI designs often take a toll. This study improves gesture recognition methods to augment usability by prioritizing a tiny idle wrist displacement and stable function on mobile.Personalization With predictive models powered by AI and the ability to adapt interfaces in real-time, personalization enables apps to create meaningful experiences for users by dynamically adjusting based on their behavior and preferences, thus ensuring they stay relevant over time. This is unlike theoretical or lab-based experiments, which have been the backbone of many mainstream studies, and this research consolidates its framework with in-field testing and user feedback to provide practical applicability. In addition, the study extracts and validates key design principles in a real-world context.Therefore, this research proposes an integrative framework that embraces innovative HCI methodologies that can contribute to providing high-quality UX in mobile applications. It embraces agility, accessibility and personalisation while maximising touch, gestures and experience. In conclusion, the proposed framework serves as a foundation for further exploration and innovation in the realm of responsive and user-centric mobile applications in the current digital ecosystem.
