“…This work has mainly focused on three major themes: the relationship between aging, familiarity and intuitive use (primarily drawing on Blackler and colleagues' work) (Blackler, Popovic, Mahar, Reddy, & Lawry, 2012;Mihajlov et al, 2015;O'Brien, 2010;Reddy, 2012); the use of image schemas in the design process to encourage intuitive use (following up on the IUUI work) (Chattopadhyay & Bolchini, 2015;Fischer, Itoh, & Inagaki, 2015a;Hurtienne, Klöckner, Diefenbach, Nass, & Maier, 2015); and the relationship between 'natural user interfaces' (NUIs) (such as touch, TEIs) and intuitive interaction (discussed in section 2.2.3) (Antle et al, 2009;Chattopadhyay & Bolchini, 2015;Macaranas, 2013;Mihajlov et al, 2015).…”
