“…It follows from the discussion of portability as enabling ‘computing’ in different contexts that, while devices might have changed in form in the push for portability, the actual use of these mobile devices is most commonly, if implicitly, understood as the manipulation of software (or apps) on a screen requiring focussed user attention. For instance, early research on the use of emerging smartphone technology discussed at length the design of user interfaces for mobile devices to replicate known computing experiences on what was seen to be a severely limited ‘screen real estate’ (Billsus, Brunk, Evans, Gladish, & Pazzani, ; MacKay, Dearman, Inkpen, & Watters, ; Nickerson, ; Pande & Gomes, ). Specifically in the literature on the adoption of m‐commerce, studies (Keith, Babb, Lowry, Furner, & Abdullat, ; Ngai & Gunasekaran, ; Wakefield & Whitten, ; Wang, Lin, & Luarn, ) have drawn on the Technology Acceptance Model (TAM) framework and have assessed (among other variables) the ease with which users can manipulate a mobile device's screen interface to navigate the screen's menu and read and compose messages (Hoehle & Venkatesh, ; Keith et al, ; Sarker & Wells, ).…”
