Welcome to Volume 3, Issue 1 of Human-Computer Interaction Perspectives (HCIP), where we delve deeper into the dynamic field of human-computer interaction (HCI). This edition features two groundbreaking papers that shed light on essential aspects of HCI research. "User Interface Prototyping" delves into the realm of tools and methods for prototyping user interfaces, enabling designers to visualize design concepts and gather valuable feedback from stakeholders. Concurrently, "Analyzing Human-Centered Design Approaches" explores methodologies for involving end-users throughout the design process, fostering collaboration and ensuring the creation of user-centric interactive systems. Join us as we navigate the intricacies of HCI, fostering innovation and excellence in user experience design.
