Contemporary information and communication technologies (ICT) greatly shaped the way we communicate nowadays. Communication technology empowers people to be more involved into each others lives and sharing moments has never been easier, especially for geographically distributed families. Unfortunately though, when it comes to technology adoption, elderly people continue to lag behind and intergenerational communication with remote family members is mostly limited to the telephone. This thesis therefore explores issues of technology adoption and attitudes towards communication with the aim to develop an accessible device that integrate older people into the digital lives of their descendants. The prototype promotes the concept of a lightweight instant messaging service and establishes a new communication channel for distance-separated multigenerational families. In order to create a design that meet elderly users needs and expectations a broad spectrum of related literature is reviewed and qualitative research is conducted to collect individual and personal information in order to create an impression of the targeted user group and identify how technology can fit into their lives. Based on resulting design and user requirements, rapid prototyping techniques are used to illustrate and iterate design ideas and discover first design flaws. The final high-fidelity prototype for the elderly users, together with a custom developed counterpart app for the younger participants, represent the results of the conducted research and design process. Finally, the evaluation of the BK64 system by means of two different field studies suggests that the newly introduced communication modality has a positive impact on the feeling of togetherness and intergenerational communication habits within a distributed family with three or more generations.
