User interface evaluation of interactive TV: a media studies perspective

Konstantinos Chorianopoulos, Diomidis Spinellis
2006 Universal Access in the Information Society  
The field of media studies has accumulated an extensive theory of TV and associated methods.  ...  The traditional user interface evaluation paradigm involving efficiency and task completion may not be adequate for the assessment of such applications.  ...  Acknowledgements We are grateful to Jens Riegelsberger and Mina Vasalou for their suggestions on early drafts of this paper.  ...

Supporting the social uses of television

David Geerts, Dirk De Grooff
2009 Proceedings of the 27th international conference on Human factors in computing systems - CHI 09  
In this paper we present twelve sociability heuristics for evaluating social TV, based on several user studies with social TV systems.  ...  Although usability guidelines exist for interactive television to ensure a usable system, there are no sociability guidelines for designing or evaluating the social interaction these systems enable.  ...  ACKNOWLEDGMENTS We would like to thank Karin, Bieke, Christof and Jeroen, as well as the anonymous reviewers, who have all helped to improve this paper.  ...
