“…Researches of innovation adoption in connection with attributes of devices (Rogers, 2010), consumer perceptions (Davis, 1993), consumer attitude (Moore & Benbasat, 1996), psychology (Hussain & Rashidi, 2015;Wozniak, Schaffner, Stanoevska-Slabeva, & Lenz-Kesekamp, 2017) and personality (Jeong et al, 2017;Rogers, 2010) have attracted prolific literature as the adoption of incremental and radical innovation of existing high-tech brands is a complex process that involves various stages such as knowledge, persuasion, decision, implementation and confirmation (Rogers, 2010). A consumer may accept the incremental/radical innovation or simply be inclined to continue using the incumbent models instead of switching to new ones (Lee & Park, 2016). Prolific literature suggests that an individual's personality traits such as innovativeness emphasised by Rogers (2010) and psychological influences such as user's engagement enforced by O'Brien and Toms (2008) are the most important traits in this regard.…”
