“…Over the past several years, a number of collaborative technology-enabled training applications emerged to provide a safer, affordable, and repetitive environment for children with ASD (Chen, 2012; Kientz, Goodwin, Hayes, & Abowd, 2013; Millen et al., 2011). Among them, collaborative games have gained prominence to train children joint attention skills (e.g., Battocchi et al., 2009; Boyle, Arnedillo-Sanchez, & Zahid, 2015; Gal, Lamash, Bauminger-Zviely, Zancanaro, & Weiss, 2016; Giusti, Zancanaro, Gal, & Weiss, 2011; Goh, Shou, Tan, & Lum, 2012; Millen et al., 2011; Piper, O’Brien, Morris, & Winograd, 2006; Rehg et al., 2013), mainly due to its inherent multiuser features to promote and facilitate collaborative work and information sharing (Edward, Greenberg, Shen, & Forlines, 2007; Silva et al., 2015). However, the majority of these games are often developed to enhance children’s social communication skills and promote cooperative works (Battocchi et al., 2009; Ben-Sasson et al., 2013; Boyle et al., 2015; Gal et al., 2016; Giusti et al., 2011; Goh et al., 2012; Hourcade, Bullock-Rest, & Hansen, 2012; Millen et al., 2011; Rehg et al., 2013; Silva et al., 2015); as such, these applications contain only one workspace where collaboration is tightly coupled (Battocchi et al., 2009; Giusti et al., 2011; Piper et al., 2006).…”
