19 R. W. Soukoreff, & I. S. MacKenzie (2003). The KeyCapture software and source code. The paper above makes the argument that language models used for text input research should be based on data captured during the text input task. To make this argument, we wrote the KeyCapture software - three programs that record every keystroke and mouse action made by somebody using a computer with the windows operating system. These programs allow researchers to observe what text users enter, and how the text was entered.
