This article reviews literature on that approach to studying the writing process. The article begins with defining the realtime computer-aided study of the writing process, tracing its historical development, and explaining the advantages it offers, then it gives a brief description of the software that has been used in the computer-aided writing process research and discusses the ways of analyzing the logged data, and it ends with overviewing the computer-aided writing process research.
