The Fundamentals of Human-Computer Interaction

Abstract

This article explains the overview of Human-Computer Interaction (HCI); cognitive models, socio-organizational issues, and stakeholder requirements; HCI and hand gesture recognition; and the multifaceted applications of HCI. HCI is a sociotechnological discipline whose goal is to bring the power of computers and communication systems to people in ways and forms that are both accessible and useful in the effective manner. HCI plays an important role in identifying the environmental and social issues which can affect the use of systems, and providing techniques to ensure the design of the system will be usable, effective, and safe. HCI draws on computer science, computer and communications engineering, graphic design, management, psychology, and sociology as it tries to make computer and communications systems ever more usable in executing tasks. HCI is an important consideration for any business that uses computers in their everyday operation.
