Abstract

Human-Machine interaction (HCI) is relevant in today’s digitization, and so is the drive to better understand fundamental concepts toward more lucid, minimalistic and intuitive design and usage. Research has focused on the underlying psychology and mechanisms of interaction so as to make human-machine interaction seamless. In a study to build a conceptual guide for interaction design, salient concepts across relevant disciplines were gathered to understand some elements of design and their effect in interaction. Secondly, another experiment was conducted to understand the cognitive consultative patterns in interaction. The outcomes of these became the foundation for the development of the model, as they affirm/deduce some basic principles for interaction. The study engaged a total of 88 participants. This study delves into the development of model to enhance the design of intuitive and minimalistic user interfaces. Grounded in cognitive science and design principles, the model seeks to transcend traditional paradigms, offering a holistic framework that harmonizes user expectations, task efficiency, and aesthetics. Through a synthesis of findings from empirical studies, this paper proposes a conceptual model grounded on usage-centered design and propels a discourse towards a model that could practically be engrained into the UI design to enhance intuitive and user-friendly designs.  It provides also a clear decision-making scheme for designers and developers to craft interfaces that transcend the subjective biases of designers in UI design.
