Paper Title
HUMAN COMPUTER INTERACTION

Abstract
Abstract- This study explores the dynamic field of Human-Computer Interaction (HCI) to better understand its nuances and make a valuable contribution to the changing field of technology design. The study uses a mixed-methods approach, combining qualitative and quantitative data to fully investigate user experiences. The primary goals are to examine HCI theories, gauge user happiness, and maximize work efficiency by improving the interface. User satisfaction progression charts and usability HeatMaps, among other visual aids, are used in the process together with user surveys and interviews. Important results highlight how HCI advancements have a revolutionary effect on work efficiency and user happiness. This Study is important because it connects theoretical concepts with real-world applications, providing designers and practitioners with useful information. Within the framework of HCI, it supports a paradigm that is user-centric and in which technology is fluidly aligned with human needs and aspirations.
