Handbook of Human-Computer Interaction

Human-computer interaction (HCI) is the study of human-computer interaction through interfaces. Such an interaction is analogous to human-to-human interaction. Graphical user interfaces and multi-modal interfaces enable humans to engage with embodied character agents. The techniques of operating systems, computer graphics, programming languages and developing environments are vital to this field. Human-machine interfaces, if poorly designed can lead to systems failure and accidents. Researc...
