A T-gov Prototype Evaluation Considering A Wide Diversity Of Users

Research on interactive Digital TV (DTV) has mostly considered a reality already established in developed countries. The offer of interactivity on TV is just emerging in some developing countries and is a source of many challenges for interaction designers, as the DTV may reach people without access to other Information and Communication Technology. This paper discusses an experiment conducted to evaluate the user interface of a t-gov application prototype, taking into account the affective state and emotions of the users. The prototype was conceived according to the DTV Brazilian scenario, aiming to shed light on the main design questions an application designer of DTV user interface faces, especially when considering a wide diversity of users, most of them first-time DTV users. © 2008 IADIS.2734Card, S., Moran, T., Newell, A., (1983) The psychology of human-computer interaction, , Hillsdale, NJ: Lawrence Erlbaum AssociatesChorianopoulos, K., Spinellis, D., User interface evaluation of interactive TV: A media studies perspective (2006) Universal Access in the Information Society, 5, pp. 209-218. , 2, pp, Springer, HeildelbergFurtado, E.S., Mayora, O., Anastassova, M., Kampf, T., Vasconcelos, P., An Investigation of iDTV User Needs in Brazilian and Italian Communities: Preliminary Cross-Cultural Findings (2007) Proceedings of Workshop on Perspectives, Challenges and Opportunities for Human-Computer Interaction in Latin America CLIHC 2007, , Cuernavaca, MexicoKutiishi, S.M., Piccolo, L.S.G., Interactive TV Services and Applications for Digital Inclusion in Brazil (2006) Proceedings of EuroITV 2006, pp. 452-453Liu, K., (2000) Semiotics in Information Systems Engineering, , Cambridge University Press(2007) Ministry of Health, 2007.
