Text entry can also be seen as a task where different subtasks are shared between the human and the computer (Chapter 20).

Text entry is also a good example of tool use (Chapter 19). A text entry method is a tool that allows the user to communicate with someone or something, typically other people or a service, using asynchronous text messages and longer documents.

Text entry can also be seen as dialogue (Chapter 18).

A fundamental goal of interaction is to provide users with tools that allow them to achieve goals that they would otherwise not have been able to achieve.

One goal of interaction is communicating intentions, for example, issuing commands to a computer, selecting graphical elements in image processing software, or entering text.

First, text entry can be seen as the transmission of typed information to a computer.
