This paper presents research data developed by the Graduate program FAE / UFMG. We treat the implications of introducing the computer as a writing support in literacy phase. Among the references are studies about literacy, such as those produced by Magda Soares (1998), Brian Street (2009), about the history of reading and the book (Chartier, 1997) and history of written culture (Gómez, 2003). Methodologically, we have adopted the principles of qualitative research, including proposals for collaborative intervention. We accompanied 6 years old children in public school computer labs in Belo Horizonte, Minas Gerais, during the year 2009 in various writing and reading on a computer screen situations and the use of programs, games, and activities with digital sphere genres.
