Identifying, understanding and explicitly involving values and cultural aspects of stakeholders have been regarded as a challenge in the design of interactive systems. There is still a lack of principled and light-weight artifacts, methods and tools for supporting designers in this task. In this paper we propose two artifacts for supporting designers in making explicit both stakeholders' values and system's requirements taking these values into account. A case study reports the use of the artifacts in the design of seven prototypes of applications for the Brazilian Interactive Digital Television. The artifacts showed to be promising for supporting designers in the complex scenario of designing value-oriented and culturally aware interactive systems.
