With the daily problem of social isolation comes an aggravation of older adults’ general health. Social Network Services like Facebook have the potential to ameliorate the social connectivity of this segment of the population. However, they are still not fully adopted by them, whether because of age-related limitations or the lack of appropriate technological skills. In this paper we argue that the development of SNSs based on technology already used by older adults, like Television, or technology which has proven to be more accessible to them, like Tablets, can improve the ability of older adults to use these systems. We report findings from a study composed of semi-structured interviews and focus groups which aimed at the development of two Facebook-based prototypes for TV and Tablet. Results show good receptiveness from older adults to perform social tasks on TV and Tablet-based applications, for interacting using alternative modalities like speech, or back-of-device tapping, and for the use of adaptation mechanisms. Informed by the study results the main contributions are the two prototypes, and a collection of recommendations regarding the design of TV and tablet based interfaces for this population.
