Interactive Digital TV (iDTV) applications suffer with problems that are inherent to the technology and their social aspects. In addition, theoretical and practical references for designing iDTV applications are not easily found. In this sense, designing for iDTV has become an increasingly complex activity. In this paper, we propose three participatory practices for supporting a situated design and evaluation of iDTV applications. The practices were articulated in a situated design process conducted inside a Brazilian TV company. The approach favored the participation of important stakeholders, supporting different design activities: from design ideas to the creation and evaluation of an interactive prototype. The results suggest the practices' usefulness for supporting design activities, indicate the benefits of a situated and participatory approach for iDTV applications, and may inspire researchers and designers in other contexts.22734136
