Social networking services have become increasingly widespread and, together with GPS equipped with mobile phones give citizens the opportunity to create new innovative types of social networks. The service is evolving, technology-centric to positioning using GPS and Google Maps Web service should also identify existing services interfaces are analysed, and be associated with basic functions of social networks to create a new innovative service. The purpose of this work is to illustrate the usercentred interaction design for mobile phones. Research design includes user requirement analysis, prototype development and usability evaluation. The results from usability evaluation in a simulated PC-based environment, support the user tasks in an efficient manner, one can work efficiently and feels that the system is sufficiently adapted to users' needs.
