Human–Computer Interaction (HCI) is an interdisciplinary academic and engineering field that investigates the reciprocal communicative relationships between human operators and computational systems across multiple layers of perception, cognition, action and feedback ^[1]. It examines how human users acquire information from system outputs, formulate cognitive intentions, execute control commands through input devices, and interpret system responses to accomplish intended task goals ^[2]. Its conceptual scope spans physical hardware interfaces, graphical software interfaces, haptic and auditory interaction channels, as well as the cognitive and ergonomic principles that govern effective and usable interaction design. HCI is not limited to any single device category or application domain; instead, it establishes fundamental principles governing human-machine communication that apply across desktop computing, mobile devices, industrial control systems and immersive environments, integrating perspectives from computer science, cognitive psychology, ergonomics, industrial design and information science ^[3].
