Neuropsychological assessment allows identification of mental function impairments that limit independent activity and social participation (e.g. Cullen et al., 2008; Jekhonen et al., 2000; Ownsworth and McKenna, 2004; Nightingale et al., 2007; O'Neill and Evans, 2009). Identifying these barriers allows one of three types of intervention: restoration of the function; acceptance of the loss of the function; and compensation for the deficient function. This chapter explores efforts to use digital technologies to overcome the impairment of mental functions to enable independent activity and encourage greater participation.
