Possible options to reduce isolation (marginality) of these persons involve: (a) caregivers' direct assistance to help them manage forms of contact with the outside world, and (b) access to new technological solutions that may enable them to control environmental events independently (and thus develop an active communication/control role within their environment) (Elliott & Walker, 2005;Lancioni et al, 2008;Naudé & Hughes, 2005;Wales & Waite, 2005). The latter option stems from the view that assistive technology constitutes a relevant resource to meet the needs of individuals with multiple disabilities (Bozzolini & Cassibba, 2008;Hoppestad, 2006;Ivanoff, Iwarsson, & Sonn, 2006;Jutai, Fuhrer, Demers, Scherer, & DeRuyter, 2005;Lancioni, Singh, et al, 2009a).…”
