“…Particularly, the advance of multi-channel and portable fNIRS hardware has enabled neuroimaging studies in more naturalistic settings. Examples of studies applying experimental procedures and paradigms unsuitable in the MRI environment include: reaching for objects or stepping in place (Nishiyori et al, 2016), setting and clearing a table (Koehler et al, 2012), engaging in face to face conversation (Suda et al, 2011; Jiang et al, 2012; Takei et al, 2013, 2014; Lloyd-Fox et al, 2015), giving a speech (Tuscan et al, 2013), watching live and televised actions (Shimada and Hiraki, 2006), using tools (Helmich et al, 2015), performing inter-individual actions coordinately (Egetemeir et al, 2011), accessing prospective memory while walking (Pinti et al, 2015) and actually driving on a highway (Yoshino et al, 2013). fNIRS has also been proposed as an alternative to uncovering cognitive and affective states for real-life application of brain-computer interface (reviewed in Strait and Scheutz, 2014).…”
