Human-Computer Interaction

The term "Human-Computer Interaction" was coined by Card, Moran, and Newell in their book which gave birth to the field, "The Psychology of Human-Computer Interaction." The term carries the connotation that unlike other tools that only have one or a few affordances (such as a hammer, useful for driving nails, but not much else), a computer has many affordances for use and this takes place in a sort of open-ended dialog between the user and the computer. However, there's a specific connotation to Card, Moran, and Newell's title. Working with an interactive computer system actually impacts cognition dynamically. Their work was really the first attempt to develop a formal cognitive engineering discipline.
