“…Despite these significant paybacks, a limited number of studies has addressed user manuals in the relevant literature, and those studies have mostly focused on whether consumers consult the manuals (Wright et al , 1982; Peterson, 1984; Mehlenbacher et al , 2002; Tsai et al , 2012), manual usage behavior of consumers (Wright et al , 1982; Jansen and Balijon, 2002) and the ideal design of the manuals (Schriver, 1993; Reinert et al , 2007; Pedraz-Delhaes et al , 2010). Some studies have examined technical documents and documentation issues for specific products, such as software or automobiles (Mitchell, 1993; Wiese et al , 2004; Novick et al , 2008; Van Loggem, 2014) or industrial products (You et al , 2001; Pham et al , 2002; Setchi et al , 2006). Another stream of research addresses user manuals as a technical documentation issue in technical communication literature (Smudde, 1993; Smart et al , 1995; Spencer and Yates, 1995; Smart et al , 2001; Setchi et al , 2006).…”
