The mobile phone keyboard is a legacy design which has its roots in mechanical typewriters. There is debate about the design of the QWERTY keyboard, with Baker (2010) suggesting the design was intended to keep typing speeds down, stating that Sholes “rejigged the letters on his machine”. David (1985) claimed the design was in response to a problem, where keys “clash and jam if struck in rapid succession” (p. 333). The QWERTY keyboard’s design is “not optimal from a physiological standpoint” (Rempel, 2008, p. 338) and, in addition, the keys are not grouped logically (Ciobanu, 2014). Anderson et al. (2009) commented that alternative keyboards “offer ergonomic benefits over the conventional, single plane QWERTY keyboard designs” (p. 35), although these alternative keyboards lack widespread acceptance.
