Elderly's Comprehension on Facebook: a Communicability Evaluation

This paper describes a qualitative research using the Communicability Evaluation Method for Collaborative Systems. The objective is to evaluate the elders' interaction with the most popular social network in the world (Facebook), using a different approach to the proposed by the HCI community: communicability. In our case, we use younger volunteers (non-elder adults) to compare the results. As a result, there was a necessity to review some interface aspects, such as the meaning system adopted by the designer. It was also realized the need to establish clearer criteria for the information organization and to correct usability and accessibility problems that influence on the communication failures that occurred during the elders' interaction with the social network.
