“…Several studies have reported that novice users have faster task completion times with fewer errors using a GUI compared to a CLI (e.g., Streitz et al, 1987). This benefit has also been observed for both novice and experienced users with tasks that are performed infrequently (Benbasat & Todd, 1993; Eberleh, Korfmacher, & Streitz, 1992; Kissel, 1995; Rauterberg, 1992; Torres-Chazaro et al, 1992; Whiteside, Jones, Levy, & Wixon, 1985b). There have also been studies showing that experienced users complete tasks more quickly with a CLI than with a GUI (Buxton, 1993; Eberleh et al, 1992, 1992; Gentner & Nielsen, 1996; Hutchins et al, 1985; Kissel, 1995; Rauterberg, 1992; Shneiderman & Maes, 1997; Streitz et al, 1987; Westerman, 1997; Whiteside et al, 1985b).…”
