In this section, a model for designing a system of information exchange is proposed. This is a group of concepts, fed by the kind of social relations in social capital, interpreted to be part of this thesis model. Subsequently, this model will become the visual component.


  • Social networking
  • Social Capital
  • Interactive system
  • Civic engagement

Social Networking

Commuters can actively use a system to interact, share information about issues related to public transport, and improve their productivity and social benefit. In the context of PT, social networking provides de opportunity for encounter, users have the possibility to share valuable information with others. This approach also implies a familiar model of interaction that aids people in their constant search for information.


Social Capital Feeds the System

In the approach of this thesis, the value in the social relations is the shared knowledge and the human relations mediated by a system, and together allow to improve the user’s experience, individually as well as collectively. Trust and reciprocity are both important, because reliability is increased when norms help to build social life, and social life requires actions that demonstrate “one’s intention to recognize the other and to be recognized in return” (Pelaprat and Brown).


Interactive System

Functional and aesthetic elements of a social interface tied in a cohesive way to bring together users with the same interest, and to motivate the exchange of information.


  • Encounter
  • Exchange
  • Reciprocate

Chat Interface


According to Norman, interaction design pursues to “enhance people’s understanding of what can be done, what is happening, and what has just occurred” (5). The proposed system flourishes upon this premise, to provide the users with the right feedback along the process, starting with an explanation about the steps required to accomplish the goals and hopefully provide and enjoyable experience.
