Dear all, We are working on a project researching the existing guidelines and checklists for designing mobile phones and smartphones for older adults (55 and older). With the literature search we have come across 9 papers that enclose/elaborate design guidelines and checklists (Pattison and Stedmon 2006; Lee 2007; Massimi et al. 2007; Van Biljon et al. 2010; Al-Razgan et al. 2012; Van Dyk et al. 2013; Díaz-Bassini and Moreno 2014; Mi et al. 2014; Loureiro and Rodrigues 2014). Because we would like to have a comprehensive insight into the topic, we are trying to discover if there are any other (published or unpublished) design guidelines for mobile phones and smartphones appropriate for older adults. We would appreciate suggestion that could help us with finding more research that dealt with design guidelines or checklists for older adults. Best, Ajda, Andraz, Vesna
